Profane Agony

(Drow of the Underdark, page 54, DnD 3.5)

[Divine]

You can channel negative energy to deal terrible pain.

Prerequisite

Rebuke undead, Death or Destruction domain

Benefit

You can spend a rebuke undead attempt as a full-round action to channel your deity's displeasure at a single living creature within 30 feet. That creature takes 3d6 points of nonlethal damage and is sickened for 1 round. A successful Fortitude save (DC 10 + one-half your level + your Cha modifier) negates the damage, but not the sickening effect.
