Rot Troll

A troll that is infused with waves of necrotic energy as it regenerates can develop a symbiotic relationship with that deathly power. The troll’s body withers, and its flesh falls away from the body as quickly as it forms. Eventually a rot troll becomes unable to regenerate, though it still heals normally. The creature courses with necrotic energy that flows out of its withered form. Simply standing near a rot troll exposes other creatures to its lethal emanations.
