Pestilence Shamblers are disgusting and dangerous offshoots of Shambling Mounds (q.v.) Found in fetid, stagnant swamplands, they pose a great danger to the unwary because of the diseases they carry. If a Pestilence Shambler strikes a victim in combat, the Disease table in the Dungeon Master's Guide must be consulted - there is a 50% chance that the injured will immediately contract one of the diseases outlined there. Further, if a 100 is rolled, a foul rotting disorder will be afflicted on the target, which acts as mummy rot!

These slimy, noisome beasts are indistinguishable from Shambling Mounds, save for a strong rotting stench (save versus Poison or suffer -1 to all attack rolls due to gagging and retching).
