Rot troll

Rot trolls were a type of troll imbued with necrotic energy.

Description
A rot troll's flesh peeled off from the skin as soon as it formed, and the troll's body withered constantly.

Abilities
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.

Combat
Due to a rot troll's rancid degeneration, standing too close to it exposed other creatures to its deadly emanations. Only acid or fire could stop this necrotic radiation.

Creation
During regeneration, a normal troll could become infected with waves of necrotic energy and form a symbiotic connection with that deathly force.

Habitats
Rot trolls could be found in the Mere of Dead Men on the Sword Coast North.
