Your touch can fill a creature with lethargy, causing a living creature to become staggered for 1 round as a melee touch attack. If you touch a staggered living creature, that creature falls asleep for 1 round instead. Undead creatures touched are staggered for a number of rounds equal to your Wisdom modifier. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.

At 8th level, you can emit a 30-foot aura that wards against death for a number of rounds per day equal to your cleric level. Living creatures in this area are immune to all death effects, energy drain, and effects that cause negative levels. This ward does not remove negative levels that a creature has already gained, but the negative levels have no effect while the creature is inside the warded area. These rounds do not need to be consecutive.

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.
