Anima

Anima is an enemy added in Revelations Chapter 2

Anima
Anima will seek out possible buffable enemies in the room. Anima will then drop his skill, and enter the enemy, buffing them. If the buffed enemy is killed, the Anima's ghost will attempt to re-enter Anima's skull. Anima will then seek out another enemy to buff. If there are no enemies left in the room, if no enemies in the room are buffable, or if Anima has already buffed two enemies, Anima will die.
