Rejuvenation (Su) A foulflow is bound to haunt the place of its death until it is dredged and all the remains are given a proper burial, the waters are hallowed, or a powerful water entity purifies the waters and banishes the foulflow. A foulflow that was reduced to 0 hit points reforms at the first dusk following its destruction with full hit points, or after 1d10 days if destroyed with positive energy.

Water-Bound (Ex) A foulflow is bound to a body of water where it died. It can walk on water or swim through its currents, but it can't move more than 30 feet from the edge of water. It heals 1 point of damage per round as long as it remains in contact with its body of water.

Water Burst (Su) A foulflow can take a full-round action to merge with the water it is bound with. On the following turn, it can re-emerge from the same body of water within 60 feet as full-round attack, striking each creatures adjacent to its new location with a wave strike that doesn't provoke attacks of opportunity.

Wave Strike (Su) A foulflow can create a sudden wave in the water it is bound with, striking a single creature within 60 feet for 3d6 points of cold damage and allowing the foulflow to make a free bull-rush or trip maneuver against the target with a +4 racial bonus to CMB involved. On a confirmed critical hit, the foulflow uses both bull-rush and trip on the target. A foulflow can produce two such waves as a full attack action.


Foulflows are malicious spirits of warriors who died violent death while crossing a river or at the coast of a lake, usually during a battle or while fleeing from one. Now, their corrupted will animates bodies made of discarded armor and tainted water to attack the living or fight endless battle with their former comrades and foes alike.
