Any living creature that takes damage from a fleshworm swarm must attempt a DC 13 Reflex save to avoid becoming infested. An infested creature takes 1d4 Constitution damage per round as the fleshworms 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 of damage to the victim automatically destroys all of the fleshworms infesting it, ending the effect prematurely. Additionally, any effect that removes disease instantly ends a fleshworm infestation, though immunity to disease offers no defense.
Fleshworms are foul, nauseating parasites that feed on flesh and use corpses as nests in which to grow. While fleshworms can derive nourishment from dead flesh, their true hunger is for the flesh of the living. Thankfully, these swarms occur only rarely, as they require the infested carcass of a Huge or larger creature and many weeks to build up the numbers necessary to constitute a swarm.
