Rot Grubs (CR 4)

Source GameMastery Guide pg. 245
Rot grubs are nauseating parasites that feed on flesh and nest in corpses. Generally, a handful of the grubs infest a single corpse at a time, and a DC 15 Perception check is enough to notice and avoid the grubs. Otherwise, 1d6 grubs swiftly burst from the carcass to burrow into the creature, which can attempt a DC 15 Reflex save to avoid the grubs (but only if the creature is aware of the grubs’ presence). Any amount of damage reduction is enough to provide immunity to infestation.

Once rot grubs have infested a living body, they burrow toward the host’s heart, brain, and other key internal organs, eventually causing death. On the first round of infestation, applying flame to the point of entry can kill the grubs and save the host, but this inflicts 1d6 points of fire damage to the victim. Cutting the grubs out also works, but the longer the grubs remain in a host, the more damage this method does. Cutting them out requires a slashing weapon and a DC 20 Heal check, and inflicts 1d6 points of damage per round that the host has been infested. If the Heal check is successful, one grub is removed. Remove disease kills any rot grubs in or on a host.
