    SPECIAL ABILITIES

    Infestation (Ex)

    Any living creature that takes damage from a rot grub swarm becomes infested unless it succeeds at a DC 19 Reflex save. On a failed save, the infested creature takes 1d4 points of Constitution damage per round as the rot grubs burrow through and consume its flesh—this effect continues as long as the victim remains in the swarm and continues for 1d6 rounds after it leaves the swarm. Any energy-based attack (including damage from negative energy) that deals at least 5 points of damage to the victim automatically destroys all of the rot grubs infesting it, ending the effect prematurely. Additionally, any effect that removes disease instantly ends a rot grub infestation. Immunity to disease offers no defense. The save DC is Constitution-based.
