Rot Grub Swarm Infested Undead (CR +1)
Undead are not harmed by an infestation of rot grubs, but if they inhabit a corporeal, non-skeletal undead and that host strikes (or is struck by) a living creature with a touch attack or natural weapon, the target is affected by the rot grub swarm’s infestation ability (DC 13), dealing 1d3 points of Constitution damage per round. The CR of an infested undead creature is increased by +1.
