Curse of Strahd
Mongrelfolk are humanoids that have undergone, or whose ancestors underwent, horrific magical transformations, to the extent that they retain only a fraction of their original being. Their humanoid bodies incorporate the features of various beasts. For example, one mongrelfolk might have the basic body shape of a dwarf with a head that combines the features of a cat and a lizard, one arm that ends in a crab’s pincer, and one leg that ends in a cloven hoof. Another might have the skin and horns of a cow, the eyes of a spider, frog’s legs, and a scaly lizard’s tail. Each mongrelfolk’s mad combination of humanoid and animal forms results in its having a slow, awkward gait. Mongrelfolk have misshapen mouths
and vocal cords. They speak fragmented Common mixed with various animal cries and nonsense.
