Able to wait under water almost indefinitely, swamp trolls are a menace in any wetland, and travelers are wise to be cautious around any body of water too deep or murky to see the bottom.

They are particularly dangerous in swamps, or areas of stagnant water, where they blend with the murk and algae.

Swamp trolls' preferred method of dispatch is drowning, although their bite and claws work just as well. Their rubbery hide is difficult for weapons to find purchase on, and is armored with scales around the joints.
