Quasits were minor Demons that originated from the Lower Realms and served more powerful fiends or corrupt mortal Spellcasters. They stood about two feet tall and resembled twisted, imp-like creatures with clawed hands, Batlike wings, and sharp fangs. Their skin varied in color, but often appeared green or brown, and was covered in warts and small horns.
Quasits could shapeshift into small animals like bats, Rats, or Toads, a power they used to spy or escape, and had the ability to magically instill fear in mortal creatures. They were naturally invisible when they wished to be and could deliver poison through their claws, making them dangerous despite their low physical strength. They often acted as Familiars to spellcasters, drawn to the Prime Material through dark summoning rituals.
