Actions

Bites.mw 0 to hit, reach 0 ft., one creature in the swarm's space. target is infested by {@dice 1d4 rot grubs. At the start of each of the target's turns, the target takes 1d6 piercing damage per rot grub infesting it. Applying fire to the bite wound before the end of the target's next turn deals 1 fire damage to the target and kills these rot grubs. After this time, these rot grubs are too far under the skin to be burned. If a target infested by rot grubs ends its turn with 0 hit points, it dies as the rot grubs burrow into its heart and kill it. Any effect that cures disease kills all rot grubs infesting the target.

Swarm of Rot Grubs

Rot grubs are finger-sized maggots that eat living or dead flesh, although they can survive on plant matter. They infest corpses and piles of decaying matter and attack living creatures that disturb them. After burrowing into the flesh of a living creature, a rot grub instinctively chews its way toward the heart in order to kill its host.

Rot grubs pose a threat both singly and as a swarm. See the accompanying stat block for the mechanics of a swarm of rot grubs. A single rot grub has no stat block. Any creature that comes into contact with it must make a 10 Dexterity saving throw. On a failed save, the rot grub burrows into the creature's flesh and deals 3 (1d6) piercing damage at the start of each of the host creature's turns. Applying fire to the wound before the end of the host creature's next turn deals 1 fire damage to the host and kills the infesting rot grub. After this time, the rot grub is too far under the host creature's skin to be burned. If a creature infested by one or more rot grubs ends its turn with 0 hit points, it dies as the grubs burrow into its heart and kill it. Any effect that cures disease kills all rot grubs infesting the target. Burning a body kills any rot grubs infesting it.
