Factions determine which creatures are hostile to each other.
- Creatures never attack the same creature (even when one of them is tamed).
- Creatures in the same faction never attack each other (except when one of them is tamed).
- Bosses are allied with all other factions except player faction (Which only include the player characters and tamed animals).
- Undead and demons are allies.
- As of patch 0.217.46, Hare is the only mob in the game in the Animal faction.
- Mistlands and Dvergr factions are not hostile to the Animal faction (It is to be assumed the former are allied to the latter in this case)
- Tamed creatures never attack other tamed creatures, players or the same creature.
