When a grodair is killed, it immediately explodes in a 15-foot-radius burst of highly pressurized water that deals 5d6 points of bludgeoning damage (DC 17 Reflex for half). After the explosion, a successful DC 25 Survival check allows a creature to recover a cluster of strange organs from the remains. This cluster functions as a decanter of endless water for 2d6 hours, but can only produce a "stream" or "fountain" effect. Failing this Survival check by 5 or more causes the cluster to burst, dealing an additional 2d6 points of damage to that creature (no save) and destroying the organs entirely. The save DC is Constitution-based.
