Water Light

''Tiny, glowing algae appear on the hide and flesh of those with bodies containing water. The algae illuminate the area with a bright light.''

With the exception of you and everything that you are carrying, all living creatures and objects that contain more than one gallon of water glow as if affected by a light spell. Once per round, as a free action, you may cause an affected creature or object to emit lightning. The affected creature or object takes 5d8 points of electricity damage. Creatures within 10 feet of the target also take 5d8 points of electricity damage (Reflex save for half damage).
