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 blood.
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.
Noble: A high level vampire that will 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).
Solomonar: A dangerous wizard who casts Level 4 spells. They always have glow, but also one of the following (which is denoting by their robe color): FIRESTORM, ICE, SHOCK, or HEAL.
