You bestow a small blessing on a target creature. Whenever the creature takes 8 or more points of damage, this spell discharges, suffusing the creature with positive energy that cures 2d8 points of damage. If used against undead, this spell is triggered in one of two ways, dealing 2d8 point of additional damage either the next time the undead target takes normal damage, or the next time the undead target is ‘healed’ by taking negative energy damage. An undead creature can apply spell resistance, and can attempt a Will save to take half damage.
