A shape-shifting monster formed from the cursed swamp muck at the base of the dreaded Black Mountain, the Sludge Demon can assume a multitude of guises and sizes. To conserve his maleficent energy, most of the time he maintains a small, compact state… but don’t let the smile and chubby face of this primary form fool you: his razor sharp teeth may be at your throat at the first opportunity. The Sludge Demon is the most powerful and fearsome of all monsters.
