A stingchuck is a foul bag made of a humanoid’s head with the brain removed and the skull heavily scored so that it bursts open when thrown.
Description: Normally filled with biting vermin, a stingchuck acts as a splash weapon. When it hits, the vermin bite and sting the target, dealing 1d6 points of damage and forcing a DC 11 Fortitude save to avoid being nauseated for 1d3 rounds. Each round a creature remains nauseated by a stingchuck, it takes 1 additional point of damage from the biting vermin. All creatures within the splash effect take 1 point of damage from the vermin but do not risk being nauseated.
