2. Blood Fury – 1, 1 (even stronger damage with faster consumption).
   
3. Blood Storm – 1, 1, 1 (strong AoE damage around Rayne – consumes all Rage points; not very good vs most (mini-)bosses, since more AoE oriented, but still may do good job vs bloated hulks for example).

5. Furnace.
   
6. Loading Bay.

2. Ferril – quasi-boss fight.

Twisted Park (a lot of ninjas and bugs):

1. Zoo Entrance - all new ninjas. 2 new ninja mini-bosses at the same time.

7. Throne room – Kagan final boss.

Regular enemies (infights are good, when happen):

1. Ranged human minions. Weak enemy. Appears, since Mansion. Ranged weapons don't break. Dangerous only, when using turret. Best for feeding. May pick up different weapons, if disarmed. Can throw knives or explosives/Molotov cocktails.
   Can use harpoon on them.
   Among Easiest.
   
2. Melee with fists or weapon human minions. One with fists hit fast, but can't protect themselves from feeding. One with melee weapons are more problematic, especially in big numbers and when one is unarmed/armed with ranged and you can't target this enemy. Melee one also problematic, when stronger enemies nearby. May pick up different weapons, if disarmed. Can throw knives or explosives/Molotov cocktails. Appear, since Mansion.
   Can use harpoon or kick attacks to disarm them or jump behind their back or use ghost feeding.
   With that said, are Easy on their own, but may be a bit Hard in big numbers in one place, especially in early game (Streets/Sewers).
   
3. Suicide bombers. Sewers only. Blow up with some delay, when near Rayne or when thrown. Can't feed on them normally, but I didn't try Aura ghost feeding.
   Harpoon could make them helpful for your fights against other enemies.
   Easy.
   
4. Shadow female/male ninja-like vampire minions. Park chapter (maybe encountered in further chapter somewhere). Weapons don't break. May block harpoon sometimes with their blade and hit fast in melee with electric sword, also throw 3 (sometimes electric) projectiles at you from distance (not a big danger). Main issue with them is not even block of harpoon, but their 3 swings in a row attack, which covers big area and register feeding from the front, instead of from the back, when standing right behind their back. Also they are very fast, so can easily stunlock, while you attack.
   Best to attack from the back still, if you want to feed or maybe use stronger ranged attacks and melee with slowmo (front/back). Ghost Feed and Enthrall are also good. Take into account that they barely restore Rage with feeding.
   Hard for regular enemies, especially if there are more than 1. Thankfully, you have a friend for a while in the Park chapter.
   
5. Bugs. Park chapter only. Swarm of bugs, which slowly moves and attacks. Never was attacked by them, but assume they hit hard, since ninja-like vampire-minions died fast from them.
   Good tactic is to run away, since you can't feed on them or can't use as death trap targets, but best tactic is to make them fight your enemies.
   Barely an enemy, so Easiest.

Mini-bosses (immune to and damage, if use harpoon, can't feed on them, weapons don't break):

1. Red female/male samurai-like mini-bosses. First encounter: Mansion's Vampire Door. Hit very hard for new non-upgraded player.
   Slowmo should help a bit. Kill with Rage.
   Hard for starting, easier later with upgrading.
   
2. Female black/grey ninja-like mini-bosses. Streets/Subway chapter.
   Slowmo to maintain Rage from hits and then use Rage to kill them.
   Easy.
   
3. Ram-like big monsters. First encounter: Sewer – flooded with blood area. Ram into an enemy, knock down and damage player or other enemies. May attack other enemies on purpose. Attack in melee with fists, if to stay too close.
   Best tactic is to make them ram into a wall (you'll hear them or see them, when they are close) and go left or right. Then attack them with available Rage upgrade active or recharge Rage. Repeat. In one place you can also make them charge into a sunlight area to kill them faster. Shields don't block damage from them.
   Easy, but tanky.
   
4. Big monsters with a hammer. Factory chapter – one of the levels after first one. Dangerous due to very damaging AoE attack. It's a bit slow, but still fast enough. Another melee attack is series of few fast hits. May attack other enemies on purpose.
   Use double Rage against them. I recommend to keep distance and Rage with Health high in case you'll meet these folks, since I have no clue, how to deal with them without full Rage (probably slowmo and attacking from the back) and there is 1 place, where you meet 2 of them in a row with only few weaker enemies before/nearby. Shields don't block damage from them.
   Hard, if not very hard (in case of low/medium Health/Rage).
   
5. Male dark ninja-like mini-bosses. Park chapter – starting from 1st level. Basically some mix of red one and black/grey one. Not a problem on their own, but there may be 2 or 1+red one nearby at some point and no (or only few) feeding targets.
   You should be upgraded at least somehow at this point. Use double Rage.
   Not that Hard, but unfortunately not the best level to feed, which makes it Harder. Thankfully, I remember only 2 encounters.
   
6. Big bloated hulks. Skyscraper chapter. I can't tell anything about them apart from that they may hit through shields and very slow. 1st encounter was against one, which I melted with triple Rage and 2nd encounter I remember was 2 at the same time repeated few times with infinite human minions and 3 turrets to shoot all of them.
   As result I have Very Easy difficulty impression.
   
7. Shooting bald males in coats mini-bosses. Skyscraper chapter. Shoot and attack fast and as result dangerous. First there are 2 of them, which I was able to handle probably only due to pure luck (they separated and fought weak enemies on each side of a room - recommend to try to do so, when possible). 2nd encounter, I remember is around last levels against one, which is quite easy at this point. Also big plus is in both cases there were weaker enemies to feed on.
   Use double Rage.
   1st encounter may be Hard, but 2nd is Easy.

Bosses (immune to and damage, if use harpoon, can't feed on them, weapons don't break):

1. Zerensky. Mansion chapter boss. Human vampire - turns into bats and changes places.
   Just attack him when he's in human (melee/ranged) and bat (ranged+aura vision) forms. Weak enemies will spawn infinitely below to sustain your Health/Rage.
   Enabling Rage will allow not to fall from bat swarm attacks.
   Very easy boss, if you learned basics of a game already.
   
2. Slezz. Sewer chapter boss. Big demonic “mother” - throws suicide bombers and flaps wings damaging and knocking down player, if player comes too close.
   To get to the heart you need to blow up Slezz's belly with suicide bombers, she throws at you (use harpoon to throw them back). She would try to protect belly with wings – to break her protection, hit periodically switch on the right on the upper floor to let water boil her. Then pull out heart with harpoon. Enemies will spawn infinitely periodically to help with healing, if needed.
   Very easy boss.
   
3. Destroy Towers. Factory quasi-boss fight.
   Don't fight boss (can't be killed) – destroy tower's engines. Usually you can do 2-3 hits, before boss will close distance (need 4, if I remember right). Use Aura vision, if lost. Enemies will spawn periodically, but infinitely.
   Task – not a boss. Easy.
   
4. Ephemera. Park boss. Shadow vampire – hits hard in melee and throws daggers.
   Destroy objects, which give big shadows: all stones, gazebo and flood dark spot below a tree using harpoon on statue. Until you'll be informed they are all destroyed – keep distance from boss. When finished with this task use Target+double Rage to fight boss. There would spawn 1 regular enemy periodically infinitely, but it may be fast ninja like enemy, so be prepared for harder/longer fight.
   Hardest boss, in my opinion due to damage and problematic feeding. Still very fast to deal, if you have full Rage.
   
5. Unraveller. Skyscraper boss. Big skeleton like crawling up and down creature – spits big round projectiles and small bones.
   Charge your pistols using enemies nearby and use strongest blowing up fire ammo (Blood Hammer), while dodging. Around 3 shots can be made, while boss tries to attack you. Then it would run away and return back shortly. Repeat.
   Very easy boss, but takes a bit long.
   
6. Xerx. Skyscraper boss. Big bio-robotic boss shooting 1-few projectiles with right arm or sending slow damaging ray of light from the skies. Also knocks down and damages, if to stand too close.
   Arena has 4 sides. 2 have small distance between columns and 2 big. Stand behind columns in 2 big areas of your choice. Attack with pistols strongest shot (Blood Hammer) both legs and arms and pull round bubbles (when they turn white from red) with harpoon (you would need side with elevation for arms - one with stairs is good). Use columns to make boss stuck and shoot columns instead of you. Avoid slow ray by moving away. Feed on weak enemies infinitely spawning periodically, using harpoon towards you. Take into account that weak enemies may get stuck, so you may need to get inside arena to make them unstuck.
   Very easy boss.
   
7. Kagan. Main boss of skyscraper and of a game. Has a lot of small damaging attacks (melee/ranged/ranged AoE). Restores health in fountain in the center of arena. Rayne restores Health and Rage there too (doesn't restore Pistol ammo, but it doesn't seem to damage him, anyway). I have no suggestions apart from using double Rage.
   Very easy boss.
