Shoosuva
Demon lords create lesser demons for the purpose of spreading chaos and terror throughout the multiverse.
Shoosuva
A shoosuva is a hyena-demon gifted by Yeenoghu to an especially powerful gnoll (typically as a fang of Yeenoghu). A shoosuva manifests shortly after a war band achieves a great victory, emerging from a billowing, fetid cloud of smoke as it arrives from the Abyss. In battle, the demon wraps its slavering jaws around one victim while lashing out with the poisonous stinger on its tail to bring down another one. A creature immobilized by the poison becomes easy pickings for any gnolls nearby.
Each shoosuva is bonded to a particular gnoll and fights alongside its master. A gnoll that has been gifted with a shoosuva is second only to a flind in status within a war band.
