Bog Trolls are not actually related to trolls, but are a type of plant creature. Covered in moss and leaves this creature cares for the swamp and the beings in it.
All encounters with bog trolls begin at a distance of 30 yards or less, since they blend into their surrounding so completely, and they surprise on a roll of 1-3 (on 1d6).
