Description:
Ocubeasts are small, fragile lesser demons usually invisible to the mundane (i.e. anyone of a non-magical nature will not see them). This makes them perfect as spies. Most magic users of a questionable alignment make use of them but also greater daemons emply them as their eyes and ears in the mortal plane, seeing through their eye (ocubeats only have one eye).
Despite this they are not natural residents of the Prime Material Plane and spells are needed to summon them. If this summoning spell is not maintained then they just pop out of existance.
Besides the central theme of an eyeball with limbs, they appear in all shapes and colours; some with wings, others with lots of legs and they are always small.
