(Deities and Demigods variant, p. 215)
You may use a death touch once per day. Your death touch is a spell-like ability that is a death effect. You must succeed at a melee touch attack against a living creature (using the rules for touch spells). When you touch, roll 1d6 per your cleric level. If the total at least equals the creature's current hit points, it dies.
The Repose domain is similar to the Death domain in the Player's Handbook, but is granted by good-aligned deities whose clerics are barred from casting evil spells.
