Left Arm is a boss fought in Baron Castle in Final Fantasy IV and appears as a part of Baigan. Whenever defeated, Baigan will regenerate it with full HP, so it's pointless to attack it. It's not immune to Slow, so inflicting Slow on it should be first priority if possible. Left Arm can attack a player using Bloodfeast to drain HP and inflict Paralysis through the use of its Constrict ability. When Baigan is defeated and this enemy is still left alive, its final action will be to use Self-Destruct.
