Drain II is an improved version of the Drain spell, found in Final Fantasy XI. It is a Black Magic spell that can be learned by Dark Knights at level 62. When cast, the spell will absorb one enemy's HP, and add it to the player's own. As an added bonus, if the amount of absorbed HP exceeds the player's maximum HP, then it will get a temporary boost; however, the spell does not work against undead enemies. Drain II may be recast every 3 minutes, for 37 MP.
