In the southeast corner of the starting room, go behind the barrels and press on the brighter wall. You will find a chamber with a Silver Shield.

Immediately after opening the first wooden door, you will see a wall with a demonic face that has a mouthful of skulls. This is a secret door. Open it to collect the Gauntlets of the Necromancer and a pair of Wand Crystals.

When you come to the room with the window, check the eastern wall for a panel with an eagle insignia. This is another secret door. Pass through it to reach a platform near the docks where you can collect a Tome of Power. Do not drop down to the water, but instead pass the corridor you arrived from and follow another one to find an Ethereal Crossbow.
You can also reach these passages via a second secret door that looks just like the first one and is located in the corridor above the window room. The actual secret tag is at the top of the stairway from this second door.

After pulling the switch that opens the sealed door, backtrack to the window room. You will find that a teleporter has opened that leads to the water outside, where you will find a Bag of Holding.

Past the third wooden door from the central area, there is a wall that looks darker. Open it to access the area behind the fake wall in the next room and collect a Tome of Power.

At the top of the stairs from the fake wall room, you will see a room with black pillars to the west. Make your way around these pillars to find a Torch and a switch. Pulling the switch opens a passage in the yellow key room.
Go through this passage and down the stairs beyond to earn a secret. An ambush will trigger. Continue heading down the stairs and a passage to the central area will open. You will find that the red column in the tower has risen and you can collect the Dragon Claw. Beware, as this red column becomes a crushing ceiling once you step under it.

After going through the yellow door, you will see a darker wall to the left of the door that leads to the stairs down. Open it to find a secret chamber where you will find a Shadowsphere.

When you reach the grey slime area, make a U-turn to the right into a passage that has a darkened wall at the end. Open the wall and pass through to find an area with Timebombs of the Ancients and a Map Scroll.

Inside the above secret, you will see another darkened wall. Open it to find the Gauntlets of the Necromancer and a Ring of Invincibility on one of the three easiest skill levels.

After collecting the green key, take the route forward. On the stairs, you will see a torch with a flickering light. Open the wall opposite this torch and head in to find a chamber containing the Wings of Wrath.

After collecting the blue key, enter the ambush chamber that has walls with a grey triangular pattern. One wall is darkened. Pass through this secret door to find a large chamber with items.

After collecting the yellow key, return to the first pair of doors. The Silver Shield will have lowered.
Pull the switch behind it and head towards the starting point. A chamber with a teleport will have opened. Go through it and collect the Tome of Power, then drop down to open a second teleport opposite the first.
Pass through this one to find yourself on the platform bordering the starting area. Collect the bonuses and pull the switches to lower the platforms holding ammo. Drop down into the well to collect the Dragon Claw.

Go through the yellow door and head right. Pull the switch that opens the doors, then go to the tower room and through to the area where the Bag of Holding is located. A chamber will have opened.
Collect the Gauntlets of the Necromancer and pull the switch. Return to the room with the lowering pillars and you will find a new passage opened in the southeast corner.
Go through to collect the Tome of Power, then continue south across the water to an island where you will find a stash of ammo. Stepping onto the island grants a secret and triggers an ambush.

From the starting area, turn left and head towards where the Gauntlets of the Necromancer are. Before you reach them, you will see a wall with a falcon insignia to your left. Press it and it will lower. Drop down into the space that is opened and walk through the teleport to reach a secret area.

Inside the top floor of the northwestern building in the first area, press the wall to the right of the door to open a secret chamber with ammo.

Go to the northeastern tower in the second area and walk on top of the wall bordering the stairs. You will see a building with Timebombs of the Ancients. Dash across the platform and onto this building to collect them as well as a Ring of Invincibility.

There is a niche at ground level in the west side of the building in the second area. Inside you will find a switch.
Pull it and head outside to the north to find a lowered platform. As the platform begins to rise, dash into the niche that contains a Morph Ovum to earn a secret.

Inside the eastern half of the building in the second area, you will find stairs to the basement. Go through the teleport that you find here to reach a secret area. From here, take either teleport to collect the Wings of Wrath and a lot of ammo.

At the start of the level, turn around and press the left-hand carving of a robed man to reveal a chamber containing the Gauntlets of the Necromancer.

Enter the second chamber that opens when you get the above secret for another credit.

In the room with many stained glass windows, one of the windows to the north is a fake wall. The sides of it are marked by hanging skulls. Pass through it to collect a Tome of Power. This chamber is also accessible via a teleport found through the door straight ahead from the green door.

In the room with many stained glass windows, one of the windows to the south is a secret door. The sides of it are also marked by hanging skulls. Pass through to reach an area with Timebombs of the Ancients.

In the northwest corner of the room with many stained glass windows, there is a secret door concealing a Map Scroll.

In the graveyard area, you will find a black demon face door to the northwest. Open it and pass through the teleport to collect a Morph Ovum hidden near the starting point.

Outside the building in the graveyard area, locate a wall on the west side that is unaligned from the rest. This secret door conceals a Shadowsphere.

Open the exit portal, but do not exit. Go through the green door and head to the grey stone corridor. A passage will have opened in the side wall.
Pass through and head to the south of the area to find a switch. Pull it to open the sealed door nearby and pass through to find the secret exit (leading to E1M9: The Graveyard).

In the chamber containing the yellow key, locate a spinal column wall separate from the others and open it to find a Bag of Holding.

After taking the blue key, go through the passage that opens right in front of you to collect bonuses.

Just after passing under the big crusher near the green door, take the left-hand passage and press the wall that appears to be a dead end to open a secret area.

In the upper level of the Dragon Claw area, run across the bridge and locate a wall of stone blocks that does not match the others.
Open it and go through, then cross the second bridge to a secret area containing a Quartz Flask on the two hardest skill levels. On the easier ones, a Ring of Invincibility can be discovered instead.

From the secret above, drop into the southernmost slime pit and follow the stairs up to a Tome of Power.

After collecting the Dragon Claw, go north through a small passage and hurry up the stairs. Ride the temporarily lowered platform and pass through the teleporter to reach a raised area near the outer green door. If you miss the platform, backtrack until you hear it lower again.

After getting the blue key, go outside and find a new passage opened just to the east of the yellow door. Inside you will find a Silver Shield, a Claw Orb, and a teleport to the Dragon Claw platform.

Just before the exit, step up on the red platform to open a passage to the south. Head through to reach a chamber containing many bonuses.

There are four hidden chambers in the corners of the pod room, each counting as a secret:

1. In the northwest corner, a Silver Shield.
2. In the northeast corner, a Shadowsphere.
3. In the southwest corner, a Ring of Invincibility.
4. In the southeast corner, a Bag of Holding.

In the northeast of the weredragon cave, there is a wall that appears lighter. Open it to find a secret chamber containing a Silver Shield, a Tome of Power and a Crystal Geode along with some smaller ammunition bonuses.

After you cross the bridge towards the green door, backtrack and find a passage opened into the weredragon cave. Go through and you will find a secret chamber opened nearby, where you can collect bonuses, including a Bag of Holding and the Hellstaff.

In the room halfway down the stairs in the north-east of the level, the wall section with the bird motif in the northwest corner contains a disciple of D'Sparil and the Hellstaff.

In the northeast corner of the room overlooking the lavafalls is a wall section with a blue banner. Open this to find a Tome of Power.

When you press the switch to reveal the exit, it will also raise a wall section in the southeast corner of the same room providing an access to a secret area.
When you head for the south corner of the room, pillars will rise releasing weredragons. Get the Bag of Holding, then proceed through the south door. The teleporter will take you back to the top of the lavafall.

Once you have been on the top of the lavafall, you can get into the section between the northern and southern openings in this area. Get the Shadowsphere.

Once you have found secret #3, a wall section will open past the lava pool where the Ring of Invincibility was found.
Take out the iron lich by using the enhanced Hellstaff, for instance. Then get the Mystic Urn and the Enchanted Shield.

This level has no secrets.

Entering the alcove on the east side of the lava river will open a closet to the north containing one or two fire gargoyles. Enter this closet to find a Crystal Geode and a Tome of Power.

Go through the blue key door and walk up a couple of steps to reach some Ethereal Arrows. As soon as you reach the arrows, turn around then go inside the north-east building in the village area to find steps leading up to a Wings of Wrath.
Use the Wings to get back to the building where you found the Phoenix Rod; the south door has opened, revealing a passage leading to a Mystic Urn as well as the secret exit (to E2M9: The Glacier).

Once you moved down the third flight of stairs in the opening room, a secret wall will lower in the southwestern alcove at the top of the stairs, revealing a Disciple of D'Sparil that guards a Bag of Holding.

Once you dropped down into the central chamber containing the giant glacier, approaching any of the stained glass windows in front of it will the lower them. You'll find several items, including the Tome of Power, a Torch and the Dragon Claw, inside.

Past the green door, in the large room with a lava pool where you'll find the blue key, approach the northeastern pillar on the western side of the room; press the wall section between the two skull torches to reveal a teleporter.
This will teleport you to a room with two hidden doors behind some skeletal textures. The one directly behind you leads to a hidden chamber containing the Phoenix Rod.

From the room containing the blue key (see secret #3), head down the stairs leading south into a room filled with several Golems and an Undead Warrior. The wall opposite from the foot of stairs where you enter contains a misaligned section; pressing against it opens up a secret compartment holding a Ring of Invincibility.

Following the passage further down from the previous secret will lead to a Undead Warrior Ghost guarding a Mystic Urn. At the northeastern corner of this room, a section of the wall has a misaligned texture, pressing it opens a secret room containing the Hellstaff.

Once you acquire the yellow key on top of the glacier, passages east and west of secret #2 will open. Inside press the switch in the southeast corner.
A floor section will lower in the northwest corner. Jump down and go through the teleporter at the end of the passage, which will teleport you to a secret room filled with several enemies as well as the Wings of Wrath and a Tome of Power.

Use the Wings of Wrath to fly up to the ledge below the stained glass window on the eastern side of the central chamber containing the giant glacier. The window will lower to reveal a secret compartment behind it with an Iron Lich or Disciple of D'Sparil (on lower difficulties) inside it.

Once you step into the room containing the exit teleporter, the southern wall of the previous room will open and reveal two teleporters. The western one will take you to a secret room overlooking the yellow key area with the Map Scroll and some ammo inside it. (#8)
The eastern one leads to a ledge with a pit separating into two halves. Drop into the pit to land in a small room you could previously see behind a portcullis in front of which you found the blue key. You will find a Mystic Urn and a switch to lower the walls beside you. (#9)

From the ledge behind the yellow key door, drop into the magma below then run to the south-west corner to find an opening in the wall.
Go through and look south-west to get a Ring of Invulnerability, then proceed east to reach a ledge with a Hellstaff as well as Lesser and/or Greater Runes.

Just before you drop into the water-filled hall on the south side of the map, you may see a switch on the north wall. Press this switch to lower a number of teleporters inside the hall, then enter any of them before they rise again to get to the ledge on the north side of the hall.
You can walk east from here to enter a room with three stacks of Mace Spheres, a Tome of Power and one or two Quartz Flasks.

Go through the green key door then head round the corner to see some murals of robed figures on either side of the steps. The center mural on the south wall has a blinking light; open it to find an Inferno Orb.

From secret #3, continue east to the chamber with the large orange steps then open the mural with the robed figure in the north-east corner to find a teleporter. The teleporter will take you to a Phoenix Rod and an Enchanted Shield.

From the blue key platform, run north-west to leap into a niche containing two gargoyles as well as a stack of Mace Spheres, one Pile of Mace Spheres and a Wings of Wrath.

Return to the start of the level after getting the green key, then head up to the top of the east staircase and follow the water down to the floor below. The silver door here has opened, revealing a staircase guarded by weredragons that leads down to the Tome of Power. Continue east into the neighboring chamber to find a Chaos Device and Greater Runes, along with a Flame Orb and an Inferno Orb.

Go through the north-west door to the labyrinth chamber then step east on to the ice. You will hear a mural open behind you - step through it before it shuts to find Gauntlets of the Necromancer.

Open the mural with the chained man on the east wall of the labyrinth room to find a Morph Ovum and a Silver Shield.

As you walk through the yellow key door you will hear a mural open behind you. Step through it before it shuts to get a Bag of Holding.

As you walk through the green key door you will hear a mural open behind you. Step through it before it shuts to get a Tome of Power.

Enter the teleporter next to the blue key to reach the neighboring chamber with weredragons and a Hellstaff. Leave this chamber then return to the green key door and head south - part of the west wall has opened, revealing a cavern with two Crystal Vials, two stacks of Mace Spheres and a Pile of Mace Spheres.

In secret #5, walk into the west wall which is slightly brighter than the surrounding walls. The wall will open to reveal one or two disciples guarding a Phoenix Rod.

As you walk through the blue key door you will hear a mural open behind you. Step through it before it shuts to get a Ring of Invulnerability.

Go to the bottom of the wide staircase near the center of the level, then go back up to the storage room to find that part of the west wall has opened, revealing a passage with sabreclaws and gargoyles. The wooden steps in this passage hold stacks of Mace Spheres and Timebombs of the Ancients.

As you approach the blue key door you will hear two platforms moving behind you. Get on the north platform and let it carry you up to a ledge with a Hellstaff.
If you run off west this ledge with the correct amount of speed you will land on a C-shaped ledge below. Open the mural of the chained man to find a Tome of Power, a Flame Orb and Lesser Runes.

From secret #2, go back to the platforms by the blue key door and get on the south platform this time. Follow the ledge and go through the wall that opens on your left to enter the square room with the Dragon Claw; entering from this direction will open another wall to the south, behind a Chaos Device. The corridor behind this wall holds various ammo pickups, as well as a Ring of Invulnerability.

After getting the blue key, return to the previous room and go to the south-west corner to find that a wall has opened revealing a switch. Press the switch to open the north wall, then head down some magma steps (which are damaging) to a cavern with weredragons guarding a Phoenix Rod on a small island. From this island, walk east to find an Enchanted Shield and a route back to the start of the level.

On the west side of the map is a brown rock with an Ethereal Crossbow. Take the crossbow then look behind the green wall in the south-west corner to find that a chamber has opened containing a Pile of Mace Spheres, a Mystic Urn, an Enchanted Shield and a Wings of Wrath.

On the west side of the map is a pit with a Dragon Claw. Take the weapon then go to the east side of the map and look for another green wall in the north-east corner where a doorway has opened. Go through and run south through some crushers to reach a Chaos Device, a Shadowsphere and a Bag of Holding.

Use the Wings of Wrath to get the ring in the eastern passage. Make sure you are close enough to the top of the pillar to trigger the secret.

Press the wall section between the two braziers to the east in the exit room. Get the Hellstaff.

Just before going down the water tunnels after having entered the right yellow door, use the trident banner to open a room with a Bag of Holding and a Silver Shield.

Inside the small yellow floor room at the warehouse, use the banner to get a doorway to one of the two ophidian cages you saw in the start of the level, containing a Phoenix Rod.

In the big stone room with the wooden thingies sticking out of the ground, do some clever climbs and get the Map Scroll. Right in front of it is a wall with a trident banner. Open it to the second ophidian cage, containing a Ring of Invincibility.

At the very beginning of the map, use the rocky wall just right of your starting position for a hidden area with a Hellstaff and a Tome of Power.

Just opposite you as you enter the yellow door temple, you can see a stone wall with two banners. Press the space between them to reveal a secret opening containing an Ethereal Crossbow.

As you enter the corridor-like area inside the small green wall themed dungeon behind the wooden doors, take a turn to the right on the very first possible opening and open the wall to a hidden room with a Bag of Holding.

As you walk down the underground barrel area inside the same dungeon, you will notice a trident-scarved wall on your left. Open it for a Tome of Power and a gargoyle.

In the caged room with the undead warriors and the three switches, press the banner-covered wall between the two switches to open a small room with yet another warrior and the Gauntlets of the Necromancer.

At the western wall of the room with the crusher, you can see a red banner between two blue ones. Use it to open a room with a Tome of Power.

As you go up the third waterfall from the crusher room, notice a wall with a bone-like, different texture from the others. Open it for the Wings of Wrath.

When you grab a Quartz Flask in the western corridor unlocked by the green key, a secret area will open right next to the eastern green door below the hangar, containing a Mystic Urn.

If you follow the western corridor to the final room with the exit, you will notice a falcon symbol on your right. Use it to open a small room with a Map Scroll and a switch.

When you step onto the teleporter in the hub chamber, you will return to the starting hall. The windows have been lowered to provide a route between the hall and the water rooms. Dodge or kill the disciples if you have not done so yet. Enter the western area to reach some Crystal Vials and the Wings of Wrath. (#1)
Enter the eastern zone to get more Crystal Vials and a Tome of Power. (#2)

The glass painting in the elongated hall will open when you either step onto or from the stairs in the pool. Behind the painting, there is a chamber with a Quartz Flask and a Shadowsphere as well as an ophidian.

As you open the southeastern door of the root-walled cage hall, you will come to a staircase. When you spot two decoration torches, press the wall in between them. You will find a small room that has a Flame Orb and health items depending on the skill level.

In the hallway with decorative walls, stop by the pair of green block walls just in front of the wooden door. You can see a symbol on the southern wall. Press it to reveal a room that is connected to the yellow key chamber by a fake window.

After picking up the green key, another part of the spiral staircase will become accessible. At the end of the new section, there is a Chaos Device as well as a Hellstaff on its own platform.

At the platform, there is a skeleton wall. Press it to gain access to a small place that contains several timebombs and some sabreclaws. (#7)
When you open the skeleton wall, another door will open in the distance. The door will reveal more sabreclaws, a few health items and a teleporter. (#8)
Enter the teleporter to reach a new area with an Enchanted Shield. (#9)
Step onto the teleporter in the previous secret area to discover yet a new room. Pick up the Morph Ovum and press the symbol wall to get back to the southwest corner of the elongated pool hall. (#10)

When you have picked up the Phoenix Rod, you can enter the northern weredragon hideout via a secret door. It is located in between the two northernmost decorative torches. The chamber holds a Tome of Power on the two easiest skill levels and some health and ammunition items on the hardest difficulty levels. (#11)
The southern hideout can be entered similarly. It has a Bag of Holding on the three easiest skill levels and some health and ammunition on the hardest ones. (#12)

When you have hit the switch to open the exit door, return to the place where you found the Phoenix Rod. A door has opened there. A passage will take you to a hidden exit teleporter (to E3M9: The Aquifer).

When you have entered the corridor behind the yellow door, proceed until you reach a step with a dark and blinking lighting. The northern wall has a decorative mask on its top. Press the wall to reveal a room with a Chaos Device and a varying amount of Quartz Flasks.

Beyond the right angle, you will find a similar step. Open the western wall to reveal a Ring of Invincibility and a collection of ammo.

In the first room behind the green door, step on any of the red pedestals to temporarily make the room with the Dragon Claw accessible.

At the next crossing, you will see a wall with the trident symbol on it. Press the wall to obtain the Gauntlets of the Necromancer.

In the center of the level, use the teleporter with the Wings of Wrath to reach the surrounding water area, along with its goodies and iron liches.
When you are ready to leave, look for a masked alcove in the eastern wall. It has a door that leads to a room with an Enchanted Shield and a teleporter back to the start of the map.

When you arrive there, you can notice that a door in front of you has opened revealing a secret room with an Inferno Orb and a Mystic Urn. (#6)
As you step onto the elevation with the Mystic Urn, a potentially empty room will open nearby for another secret. (#7)

Just before the yellow key is a hall lined with braziers. Press the switch hidden in the south-west column to open part of the south wall, revealing one or two sabreclaws guarding a Hellstaff, a Crystal Vial and Lesser Runes. (#1)
In the same hall as secret #1, press the switch hidden in the north-west column to open part of the north wall, revealing one or two sabreclaws guarding a Torch, Crystal Vials and Lesser Runes. (#2)

Taking the yellow key will open a stained-glass window to the east, revealing one or more disciples guarding a teleporter. The teleporter will send you to the cage north-east of the starting point, which contains a variety of ammo pickups as well as a Phoenix Rod, a Ring of Invulnerability, a Tome of Power and an Enchanted Shield.

In the stone corridor on the east side of the map, enter the center alcove on the west side to open a wall with a blue banner in front of you. Go up the steps to a ledge with various items including Timebombs of the Ancients and a Pile of Mace Spheres.

When you have entered the yellow door, you will find yourself in a gloomy hallway with many alcoves. At the western end, there are two switches. You need to press the southern one to open the second main door, but the switch will also open the back walls of some of the alcoves. Enter the exposed room in the north to get a Silver Shield along with health and ammunition items. (#1)
A room in the south has been revealed similarly. The place holds a Mystic Urn, a varying amount of Quartz Flasks and some ammunition. (#2)

The northern switch will raise the starting area so that you can step onto the barrier there and run over a gap to a new zone.
A Phoenix Rod and an Enchanted Shield can be found there. North of the weapon is a passage that can be used to get to a Tome of Power and back to the start. However, a floor will lower in the west while you proceed.
It will reveal a shortcut staircase to secret 2, but when you enter the familiar area again and face to the east, you will notice that an alcove with a Bag of Holding has become accessible. The place counts as a secret.

When you have the bag, return to the bottom of the aforementioned staircase and go to the Phoenix Rod's location. The doorways around it can now be entered, and you can get a Map Scroll.

Another staircase can be accessed near the scroll. Enter the stairs, and when you arrive at the long flat section at the bottom, face to the north and press the wall to lower it as a lift. On the top, there is a room with many timebombs, a new Bag of Holding and some nitrogolems. (#5)
Proceed to the eastern end of the staircase and press the back wall to open it. Another door will open behind it revealing a varying amount of ophidians, a Pile of Mace Spheres, a second Mystic Urn and yet a third Bag of Holding. (#6)

At the blue door, you will find two banners. Go through the false wall between them to find a room with two ophidians. They were placed there to fire through a false window. In addition, the area contains some Mace Spheres, a Morph Ovum, an Inferno Orb and Greater Runes.

When you enter the water of the maulotaur yard behind the green door, four wall pillars will open. Two of them are located at the northern staircase on the other side of the green door. These pillars have revealed a chamber with a Shadowsphere. (#8)
The remaining two pillars have given access to another chamber at the southern staircase. The area holds a Tome of Power. (#9)

When you are about to take the blue key, the water level of the maulotaur yard will go down, and a sheltered area will be exposed at the bottom. There are the Wings of Wrath, ammunition for the Hellstaff and a varying amount of iron liches. Use the wings or the teleporter to return up.

Open the horse mural opposite the yellow key door to find one to three weredragons guarding a Tome of Power and a Claw Orb.

In the room with four teleporters, enter the north-west teleporter then press the switch on the north wall. When you return to the teleporter room you will see that the south-west teleporter has lowered; this teleporter is fake (it has no teleport glitter), but stepping on it will open the south wall and reveal one to three disciples guarding a Hellstaff.

From the chamber with the green key, open the misaligned south wall to find one or two weredragons guarding a number of Timebombs of the Ancients.

Just before reaching the bridge to the blue key, you must walk through a water pool containing a weredragon. Open the west wall before this pool, next to a Flame Orb, to find a Phoenix Rod.

Next to the blue key is a Wings of Wrath. As soon as you pick it up, activate it then fly west over the sludge pit to a ledge with various ammo pickups.

From secret #5, fly east over the sludge until you reach another ledge in the south-east corner with more ammo pickups.

Entering the cavern with the blue key opens four closets in the large cavern you passed through after passing the green key door, all of which count as separate secrets. The first closet is in the south-east corner of the water pool and holds a Mystic Urn. (#7)
The second closet is in the north-west corner of the water pool and holds a Map Scroll. (#8)
The third closet is east of the water pool, in a brightly-lit sector with Gauntlets of the Necromancer, and holds a Tome of Power. (#9)
The final closet is south of the passage leading into this cavern, and holds a Chaos Device. (#10)

In the start room, you can notice a wall that is slightly different from the others and that does not scroll. Open it. The room behind contains a Tome of Power, a Bag of Holding, a Quartz Flask and a Chaos Device.

When you have flown to the southern ledge in the boss arena, go to the southeast corner of it. Press the wall with a distinctive banner to uncover a room with a Mystic Urn. (#2)
The southwest corner has a similar wall. Press it to reveal a room that holds a Ring of Invincibility. (#3)

In the gauntlets room, following the passage behind the eagle shaped wall and returning to the starting room.

In the dark room in the water, gaining access to the teleporter between two hanging skulls, and getting to the elevated ledge.

Past the green door, after hitting the switch, stepping on the teleporter in the northeastern cubicle, and walking on the upper floor in the next room.

This level has no secrets.

In the metallic hall, the section with the fourteenth timebomb is special: instead of becoming darkened, its lighting will start to blink as a signal that there's a secret wall. Enter it to reach a long passage with a room at its end.

After taking the green key and going up the elevator, you will open two secret passages back in the storeroom. The passages lead to a room that, in turn, leads to a staircase. When you go upstairs, you will meet a maulotaur there. The maulotaur's chamber is a cache for a Map Scroll, a Bag of Holding and an Inferno Orb.

The northwestern orthogonal room with the Bag of Holding has an eagle insignia on a wall. Press it to reveal more of similar architecture. The uncovered place contains some Mace Spheres and an Energy Orb.

When you press the fourth switch near the sepulcher, a wall will also descend in the eastern nitrogolem room. Enter the narrow corridor beyond the opened wall and you will get behind the windows where the undead warriors could fire at you. (#1)
The mentioned switch has also opened a wall in the opposite nitrogolem room. Collect the Enchanted Shield at the end of the revealed corridor, and you will open a route back to the courtyard. (#2)

In the hall with the ornamental platform, there is a staircase that allows you to reach the structure. The long top step is actually an elevator that can be activated by pressing the switch in its eastern wall. On the bottom of the shaft, there is an underground corridor holding a Phoenix Rod.

The switch in the starting area (available after visiting other rooms at the corners of the area) will lower the high ledge in the center hall giving access to the northern section of the building.

There is a fake wall near the iron lich in the secret northern section (see secret #4 above). While it seems that the wall only conceals a room with a Ring of Invincibility, crossing it will also open new areas in the other corridor. (#5)
The western corridor now has an access to two side rooms. One holds the Wings of Wrath while the other contains a Bag of Holding and the entrance to the secret level (E4M9: Mausoleum). (#6)

The lava lake on the west side of the map has three branches that go to the east, each of which leads to a secret door with undead warriors inside: the further south contains a Shadowsphere. (#1)
The branch of the medium has some Quartz Flasks. (#2)
The northern branch contains ammunition and a Mystic Urn. (#3)

In the eastern room with long stairs, the southeast landing has a blue banner that hides a door to a secret chamber, with health, ammo and the Wings of Wrath.

After entering to the exit room, and push the switches, go back to the starting room. Go east to the first intersection and then turn south. Enter the door on the right and go to the northwest corner of the room and push the switch. This will reveal another Iron Lich and an Enchanted Shield.

When you pick up the blue key, you will open many disciple rooms in the north. However, that very same trigger will also open the wall with the eagle insignia near the place you got the Hellstaff. Return there to find a new area.

Go to the exit room, then immediately run out again and head to the chained man lift to the north that has lowered to reveal a passageway. This leads you to the room overlooking the lava bridge area, where you can collect the Phoenix Rod.

From the starting castle, run off into the lava pit in the northwest direction to where there's a small ledge with a crystal vial. The wall right behind this ledge is pass-through leading you to a secret chamber with a Morph Ovum and a teleport that takes you to the gibbet.

In the yellow key room, step onto the lift, then immediately cross over to the matching lift that lowers when you do so. Ride it up to a secret containing a Ring of Invulnerability. If missed, the access to this secret cannot be re-triggered.

After collecting the yellow key, investigate the northern alcove that opened below. The unusually large green block marks a secret door leading to a Map Scroll and a second door behind which the Mystic Urn and an Inferno Orb can be found.

In the chapel stained glass room, dash from the balcony into the alcove of the D'Sparil window. It opens, and entering grants access a secret chamber containing a Tome of Power behind you.

When collecting the green key, doors temporarily open across the room to either side of the horsemen panel, leading to a small chamber containing a Chaos Device. This can be re-triggered as desired.

The yellow key sector, mandatory for completion.

Both secrets are located at west and east elevated side passages where there are barred windows, through a secret door marked with spinal columns.

After you get the green key, or after you enter the room where you found it, quickly jump down into the river to the south. At the east end, you will find that a lift has been lowered, allowing you to drop down into a cave with ammo, a Phoenix Rod, and health items.

The lava chambers that are revealed as a side area after visiting the switch that lowers the yellow key. Extra Quartz Flasks, weapons and an Enchanted Shield can be found in this area.

Past the yellow door, in the ambush room with the barrels, the north side has a fake wall. Behind it is a Tome of Power and a switch which temporarily lowers a nearby lift.
This lift takes you up to a ledge overlooking the lava chambers, with a Morph Ovum.

A side area off of the rivers beyond the pod room is noticeable by a shadowed overhang. Going here drops a lift leading to an Enchanted Shield.

Across from the switch after the green door, there is a secret door to the left of the hanging skull. A Ring of Invulnerability can be found overlooking the lava chambers.

Near the ledge overlooking the yellow door, there are a couple of secret chambers marked with hanging skulls. One contains a Phoenix Rod, while the opposite contains Wings of Wrath.

Backtrack to the very start of the level any time after you've climbed to the top of the stairs leading out of that chamber. Walls have lowered revealing some items including a Bag of Holding as well as some ophidians guarding the stash.

The iron lich monster closet that opens when collecting the yellow key is considered a secret.

In the large room with barrels along the sides, past the green door, drop off of the lift onto the barrels themselves and use them as a walkway.
Following the north side path leads you to an Enchanted Shield beyond which is a secret door allowing you to escape the lowered chamber you drop off into.

Do the steps necessary to complete the level, but instead of taking the standard exit, go back to the bridge room and find a new chamber open in the water near the blue door.
Take the teleport inside and find yourself in the ophidian tower, where you can pull a switch that opens the wooden bars. In the chamber past the bars, the southeast wall is fake, with gargoyles coming out from behind it. Beyond the fake wall is an alternate exit which will take you to E5M9: Skein of D'Sparil.

This level has no secrets.

Right behind you, at the start, is a secret door leading to a lift which leads to a small area with a Bag of Holding and a Morph Ovum.

After getting the yellow key, two secret rooms will open up to the west and south. They contain ammo and health items.

Behind the yellow door is a room with stained glass windows. There's also a switch in there; if you push it, the northwest window will change. You can now walk through it to come to a room with four teleporters and a Map Scroll.

A wall lowers when you take the Hellstaff, and entering the area behind it counts as a secret.

In the green key room, there's a switch along the side of the area that lowers a section of the outer walkway down to the lava. This reveals a teleport chamber through which you can get behind some of the barred closets on the sides of this area. This also applies to secret #3, at the opposite side.

Atop one of the timebomb lifts past the green door, there's another spinal column wall which opens to a passageway where the Phoenix Rod can be found.

The northwest of the six teleports in the teleport nexus takes you to a balcony over the green key room, which counts as a secret.

Enter the exit chamber to open the secret sector, then backtrack to the silver room, hit the small red-eyed skull wall with any weapon, causing it to open. You can now go straight through and around the bend to get to the lava chamber containing a Mystic Urn. The north side also contains a Ring of Invulnerability for another secret.

When inside the main wall of the southwestern building, push on the southernmost square fortification, where the texture pattern is broken, to find a Morph Ovum.

When you find the blue key, hit the east wall next to the hanging skull to lower a passage leading to a Chaos Device.

This level has no secrets.
