Apostate

Apostates are undead priest enemies found in the Undying Shores that revive the souls of slain enemies. They are exclusive to the Fatal Falls DLC.

Behavior
When the player is not nearby, the Apostate will continuously revive previously killed enemies, as well as "awaken" any Clumsy Swordsmen, Dastardly Archers, and Compulsive Gravediggers that are laying inactive on the ground. When the player is on the same platform as the Apostate, but some distance away, it will attempt to protect itself by creating a magic barrier, but will still continue reviving enemies. If the player gets within melee range, the Apostate will attempt to strike them with its lantern.

Strategy
Due to the inherent capabilities of this enemy to revive their fallen comrades, it is generally a good idea to prioritize killing the Apostate as soon as possible, as the longer they are left alive, the longer they have to revive more enemies. If an Apostate dies, the enemies it revived die alongside it.

HOWEVER, if the player is confident in their capabilities, enemies can be endlessly farmed for health via mutations such as What Doesn't Kill Me, Frenzy, Vampirism (not recommended, however, due to the player having a time limit) and other methods. It can also be used to rack up gold via a mix of Get Rich Quick and Velocity, potentially allowing the player to speed through future levels via the Greed shield's Legendary affix, Gold Digger, or make them invincible with Gold Plating.
