Alistair's Profane Flame

Black flames erupt in the target's body, draining them of their vitality and life force. The target must make a constituition saving throw, taking 3d8 on a failed save and half as much in a successful one. If this spell is used in a undead, it does not make a saving throw, and is healed instead.

At Higher Levels. for each level above 2nd, the damage increases by 1d8.
