A rot troll's flesh peeled off from the skin as soon as it formed, and the troll's body withered constantly.
Unlike a normal troll, a rot troll eventually lost its ability to regenerate, but it still healed properly. The monster was pulsing with necrotic energy, which was emitted from its withering shape.
During regeneration, a normal troll could become infected with waves of necrotic energy and form a symbiotic connection with that deathly force.
