Source: Advanced Player's Guide, p. 46
You can cause terrible wounds to appear on a creature with a melee touch attack. This attack deals 1d6 points of negative energy damage +1 point for every two oracle levels you possess. If used against an undead creature, it heals damage and grants a +2 channel resistance for 1 minute. You can use this ability a number of times per day equal to 3 + your Charisma modifier.
