Banes
Besides each class's main progression, there is also a chain of "banes", accessories that, while worn, cause attacks to apply powerful debuffs to specific types of enemies and bosses. Bosses have a partial weakness to a certain bane that is available before fighting them, and a full weakness to a bane that is available directly after defeating them.
