Repose

At 1st level, you can fill a living creature with lethargy by hitting it with a melee touch attack, causing it to become staggered for 1 round. If the target is already staggered, it falls asleep for 1 round instead. An undead creature that's touched is staggered for a number of rounds equal to your Wisdom modifier (minimum 1). At 10th level, when using channel energy to heal living creatures, you can take a swift action on that same turn to also deal damage to undead creatures (as your channel energy ability). Undead take an amount of damage equal to half the amount healed.
