Shoosuva

Shoosuvas are hyena-like demons.

Appearance
A shoosuva is a ten-foot-long skeletal creature, somewhat catlike and somewhat doglike, with large spined protrusions along its back and a long, scorpion-like tail with a foot-long hooked stinger at the end.

Abilities
The following is drawn from Volo's Guide to Monsters, but some abilities are demonstrated onstream.
 * Condition Immunities: Charmed, frightened, poisoned
 * Damage Immunities: Poison
 * Damage Resistances: Cold, fire, lightning, bludgeoning/piercing/slashing from nonmagical weapons
 * Rampage: If the shoosuva's melee attack reduces a creature to 0 hit points, the shoosuva can use a bonus action to move up to half its speed and make an additional bite attack.
 * Tail Stinger: An attack that, on a hit, forces the target to make a Constitution check or become poisoned and paralyzed.

Known shoosuvas
The Mighty Nein defeated three shoosuvas who had slipped through a rift from the Abyss to the space under Zorth's livery. These rifts were caused by Abyssal anchors that had been placed by members of the Angel of Irons cult.
