Imps whose psychic gate becomes unstable may see too many otherworldly entities entering their body. As a result, the physical vessel will no longer be able to contain so many beings within it, and they will make their home grow forcefully. Demonoids can reach a height of 4 metres. Their body is filled with festering open wounds spiky protrusions, fluids endlessly oozing from their impossibly shaped muscles. Most psychics regard demonoids as a pest, as they are useless for manual labour, but they do make formidable soldiers if the caster can manage to persuade them back into their service.
Demonoids have complex psychic programmed spells written all the way into their innards, usually fire-based and much more powerful than those of their more humanlike predecessors.
