D&D 2024 monster: Rot Troll. Source: Mordenkainen's Tome of Foes. challenge rating 9, creature type Giant, Large size, speed 30 ft. 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. Trolls Trolls that are nearly obliterated but survive and regenerate from mere scraps of flesh can display bizarre mutations. One of these warped trolls is especially likely to arise if the creature regenerates in the presence of magical emanations, planar energy, disease, or death on a vast scale, or if its body was damaged by elemental forces. These mutated forms can also be produced and shaped by the ritual magic of evil spellcasters. Giant Large 30 ft.
