Monsters
Vampires
Vampires are fast and strong fighters, but they have two big weaknesses: sunlight and water. If vampires step over blood, they will drink it to gain health. You can quickly de-escalate a fight with vampires by using a Blood potion and turning vamp yourself.
Grunt: One of the lowliest enemies in the game, but fast.
Devourer: Teleports to and immediately drinks blood to heal.
Hawker: Functions as a shop and is not aggressive (in previous versions, Hawkers had the same aggro mechanics as other vampires).
Brawler: Lumbering vampires that can throw you one tile.
Knight: A vampire with very high resistances which is most easily killed by sunlight.
Noble: A high level vampire that will go out of its way to move to blood tiles in the middle of combat to heal.
Humans
Humans are fairly slow and weak, but they cast powerful magic. Like most enemies, humans cannot see in the dark. Drinking a Soul Elixir around humans will instantly make them friendly to you.
Mercenary: The weakest human opponent. Casts one of the following Level 1 spells: FIRESTORM, ICE or SHOCK.
Marauder: A stronger and more durable version of the Mercenary. Casts the same Level 1 spells, but with a higher cast rate than Mercenaries.
Hunter: A mid level human that casts ENRAGE.
Artificer: The only human that can become aggressive against human players (if you attack their golems). They can create golems and buff them.
Solomonar: A dangerous wizard who casts Level 3 spells. They always know the Glow spell, but also one of the following (which is denoted by their robe color): FIRESTORM, ICE, SHOCK, or HEAL.
Golems
Golems are extremely slow, but heavy hitting. Being held together by magical electricity, all golems are healed by the ELECTRIC type. But they are also the only monster type vulnerable to BLAST damage. Golems do not bleed.
Lapis Golem: A basic golem made of lapis lazuli that can prove to be deadly early on if underestimated.
Sunstone Golem: A golem composed of stone that emits sunlight. The radius of the sunlight repeatedly expands outwards and then resets.
Ice Golem: Attacks with ICE damage, which can slow you. Ice Golems have poor resistances against SUNLIGHT, WATER, and FIRE.
Electric Golem: Attacks with ELECTRIC damage and casts SHOCK.
Ruby Golem: A golem composed of ruby which is far stronger than all others.
Magma Golem: Attacks with FIRE and healed by FIRE. This high level golem leaves pools of lava in its path.
Plants & Fungi
These enemies are generally not threats, but they have a few tricks up their sleeves. They do not bleed.
Green Man: A half man, half plant. When hit by SUNLIGHT (which heals them) they grow much stronger. Green Men turn into Husks upon death from which a Red, Blue, or Green Toadstool grows.
Elder Green Man: A high level Green Man. Turns into a Death Husk upon death from which a Death Cap Toadstool grows.
Blue Toadstool: Toadstools only move at night, but they are always active. Blue ones cast a MIASMA that causes delusion.
Red Toadstool: Casts a MIASMA that causes confusion.
Yellow Toadstool: Casts a MIASMA that causes poison.
Death Cap Toadstool: Stronger than other Toadstools. Casts a MIASMA that causes heavy poison.
Beasts
The hotel is crawling with all sorts of hostile beasts. Many do POISON damage and most are good sources of blood.
Bat: Bats are more annoying than else. They flitter around you with weak, but fast attacks. Flying.
Toad: Toads jump around randomly and attack you with their tongue from 2 tiles away.
Poison Toad: A toad this is sometimes poisonous.

Killer Bee: A much more aggressive type of bee, but this one doesn't lose its stinger. Flying.
Baby Spider: On its own, a harmless little spider. Its poison can stun you, however.

Rat Soldier: One of the weakest enemies. A safe way to get blood for vampires.
Rat Assassin: A mid level enemy that also does POISON damage.
