Special Traits

  • Keen Smell. The troll has advantage on Wisdom (Perception) checks that rely on smell.
  • Regeneration. The troll regains 8 hit points at the start of its turn. If the troll takes fire damage, this trait doesn’t function at the start of the troll’s next turn. The troll dies only if it starts its turn with 0 hit points and doesn’t regenerate.

Living far beneath the city is a disgusting creature. The sewer troll combines some aspects of a giant frog and some aspects of a slimy troll. It uses powerful arms and legs to move around the sewers. The troll surprises many creatures with its ability to leap like a frog.

Not the most motivated individuals, they wander aimlessly in the shadowy underground.

Sewer Swimmer. This monster spends some of its time swimming in the dirty, foul-smelling sewer water. They feed on the strange fish and odd plants in the muck and mire. If they smell one of the humanoids that lives underground, they will attempt to find some extra energy and hunt it down.

Lazy Lanky Lost. These sloth-like giants are usually very lazy and will use the least amount of effort to get the food they need. They aren’t too bright and have literally been scared by their own shadows before.
