Pusks, also known as Dretches or Sloth Demons, are among the weakest of Demons, but they are no less vicious or cruel for it. They're bullies, who will take out their frustration on anything smaller or weaker than themselves.
Pusks have a vaguely humanoid appearance, with awkwardly lengthed limbs and loose, slacking skin that hangs off of their frames. They're small, somewhere between a halfling and a dwarf in size, and in the Demon Wastes where they are most often found, they are at the bottom of the food chain. For most pusks, their fate is to be killed by a more powerful demon for sport, or by the Ghaash'kala or one of the Carrion Tribes.
Most pusks can briefly escape from the Wastes by being summoned, as they are one of the easiest demons to summon. They can be quite accomodating for their summoners, as mistreatment at the hand of some upstart wizard or warlock is still better than the Wastes.
