Sentinel Island mission
Overall not a challenging map, but its sizes and pages' spawns make it tedious. 😣
Please, make sure to prepare some Resurrection Statues just in case.
Difficulty doesn't stack!


Mains (objective completion related)
Forbidden knowledge
Complete the book of the order


You must find 30 lewd pages. Keep your eyes on bottom left - when the book glows, this means a page is nearby. Wiggle the book until its writings glow even more intense, pinpointing the page direction.


Sanguine ceremony
Create 4 accursed blood spheres
(in one run)

Gather 3 vials and collect blood from corpses, then empty the liquid into an altar. Some bodies have only one portion, others up to 4. Pure RNG.


Anyways, once an altar is filled 3 times, a blood sphere is formed. Now fill up 3 more.
Please note, that completing one specific quest (feeding Primordial) counts as one blood sphere!


Peace and tranquility
Banish the ancient one
(find 30 pages, create 4 blood spheres, reach the portal and shoo the demon)

Equanimity
Banish the ancient one on a mad man mission
(find 30 pages, create 4 blood spheres, reach the portal and shoo the demon, but it's harder)

My advice would be doing a giant circle sweep around the island. Each time I went in diagonals into the centre, I kept dying (skill issue I guess).
By going in the circle you are able to spot altars and points of interests (to your left) and be within safe zones reach (to your right). It's a big map with many random spots for pages, so take your time.

I think the optimal route is to move to North hugging East. Get 1st altar done, closest to your spawn. Complete 2nd altar somewhere next to Windmill. Clear out the Primordial Pit, that's your 3rd blood orb. Shortly before reaching the Devoured House you should have found all 30 pages and finish 4th altar. Always investigate pyramids tops - they may have double page spawn :O


Side quests
(don't need them for the main objective, but you get nice freebies)
In Death
Get killed by the otherwordly (the forest dwellings)
(not exactly a side quest, but better get it done before attempting a run)

Devoted cultist
Collect 25 lost artifacts
(these are shiny metal cards, scrolls of wisdom and tempting oval objects.. Paige, yes!)

Most common spawn spots are within buildings, around black altars and caves entrances. Completing a side quest often rewards another item.


Primordial cleansing
Purify the depths and destroy the primordial of the pit


This one is a fun objective. Located somewhere to South West, with a pyramid next to it and squeaky lurking spawnling.


Make your way down, then instantly left and continue to left side inside and into another exposed edge and dive into a hole. Keep your lantern fuelled up, clear the area, grab the tentacles - your hands must be empty i.e. not holding shoggoths, heads, etc!


Then step into this Rick's portal and instantly from the place you appear, make another step forward and feed this succulent being to its bigger kind.


Fiend in the walls
Banish the creature haunting the house near the cliffs


The building is in the north.


There, you'll need 4 candles 😉


1 is in the basement, other 3 in upper rooms.
Get them, place in front of the teethy guest and say bon voyage!


The shadow below
Banish the entity lurking in the depths of the devoured house


Located in the east, you can see ripped structure.


Use the lantern to erase 4 seals (top right, ground left, bottom behind and in the area with the Entity to the left. Once all seals are gone, use the lantern or enchanted page to banish the creature.


Primordial banishment
Feed the primordial being until it ceases to exist


North-east location, very close to the default spawn.


You need to feed four (4!) baby venoms. Don't forget the lamb sauce.
Stock up on spell pages and lantern oil. Clear out wall protoplasmas and you'll discover a stairs leading down. This is where the trophy is earned and serotonin achieved.


I dunno if they spawn randomly or not, for me there's always one by the main entrance, another one literally behind the wall, found 3rd somewhere to the left by the grid and 4th next to the feeding area. Good luck.


This map just doesn't end, does it? 🤣
Summoning the Old One
Alright, here's the last quest.
Still need to find 30 pages and fill up the altars to create 4 blood spheres.
Then, find four caves by going from East to West and sticking to South.
On the map - see these four small circles? In the game - keep your eyes open for rock formation.


Inside the caves create summoning pieces. Once that's complete, you'll be automatically taken to the main altar, where you summon you know who...
Please note, this ritual will ruin your run, so do it separately.


Chaos and Destruction
Summon the old one


Devastation
Summon the old one on a mad man mission
Innsmouth mission
Very simple and short mission with plenty of safe zones to hide in. Difficulty doesn't stack.🙄
I tried to measure the time intervals, but they were very uneven and random. Sometimes 1.5minute, sometimes up to 2mins, with 1min of raging monsters. Meh, enjoy it as it is.


Terrors of the deep
Succumb to the creatures of the sea
(die to the fish folks, later show the police where they touched you)

Broken curse
Cleanse the shrine of Innsmouth
(find the book and 25 pages, 3 relics, 2 keys, complete the cleansing)

The shadow over Innsmouth
Cleanse the shrine of Innsmouth, on mad man difficulty
(find the book and 25 pages, 3 relics, 2 keys, complete the cleansing, but it's slightly harder)

Obscure seals
Retrieve the lost seals from Innsmouth


Here's where you can find them:
1) in the tavern on this sticky table


far left by the shore opposite the Lighthouse


far right by the shore inside a safe house
The Abyssal Temple mission
This is a tough run. And difficulty doesn't stack.😐
There's a total of five (5!) areas to survive. Pages, relics, seals' spawns can be a poo, so...
good luck, Cultists


Axiom of the malignant
Witness the reveal of a diety


Magnificent veracity
Witness the reveal of a diety, on mad man difficulty
(dayem, them legs 😏)

Miserable demise
Perish in the throne room of the abyssal temple
(gitgut?)

When told to use the Triangle artifact - DO NOT.
Please note, that if you made a Resurrection Statute earlier, it won't work. Yes, you'll fail the run.


Forsaken relics
Retrieve all lost artifacts from the abyssal temple


That's what they look like. Cute stone figures. Gotta capture them all?!


I'm not responsible if they spawn elsewhere =P Here's where I found mine.

1) In the first cave to the right on the boulder:


2) After stairs check above the door way:


3) When searching for relics and mask:


4) In the big hall with broken seals check in the vase:


5) When carrying prehistoric smooth balls - next to the headless statue:
something lurking around here

Yeah, took me around 5 minutes to realize they were on stairs lmao, it blended very well to the background. But damn, it was a blast. Thanks for the help! :P
