Factions

Every object and creature in Core Keeper that deals damage is a part of a faction. This determines what creatures it can attack and be attacked by. Creatures typically cannot damage other creatures in the same faction.

Some armor, accessories and set bonuses allow the player to become allied with other factions (e.g. the King Slime Crown and Royal Gel set bonus), meaning they can no longer attack or be attacked by creatures in those particular factions.
