Associated Domain: Death.
Death’s Kiss (Su): You can cause a creature to take on some of the traits of the undead with a melee touch attack. Touched creatures are treated as undead for the purposes of effects that heal or cause damage based on positive and negative energy. This effect lasts for a number of rounds equal to 1/2 your cleric level (minimum 1). It does not apply to the Turn Undead or Command Undead feats. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
