Cruorhulk

Echolocation. The cruorhulk can't use its blindsight while deafened.

Keen Hearing. The cruorhulk has advantage on Wisdom (Perception) checks that rely on hearing.

Flying Leap. Although it can no longer fly, the cruorhulk can still use its wings to increase the distance of its leaps. The cruorhulk's long jump is up to 30 ft. and its high jump is up to 15 ft., with or without a running start.

Regeneration. The cruorhulk regains 20 hit points at the start of its turn if it has at least 1 hit point and isn't in direct sunlight or running water. If the cruorhulk takes radiant damage or damage from holy water, this trait doesn't function at the start of the cruorhulk's next turn.

Multiattack. The cruorhulk makes three attacks, two with its claws and one with its bite.

Claws. Melee Weapon Attack: +10 to hit, reach 10 ft., one creature. Hit: 15 (2d8+6) slashing damage. Instead of dealing damage, the cruorhulk can grapple the target (escape DC 18).

Bite. Melee Weapon Attack: +10 to hit, reach 5 ft., one creature. Hit: 22 (3d10+6) piercing damage. If this attack is made against a target that is grappled by the cruorhulk, it is made with advantage and deals an additional 11 (2d10) necrotic damage.

Deadly Leap. If the cruorhulk jumps at least 15 ft. as part of its movement, it can then use this action to land on its feet in a space that contains one or more other creatures.  Each of those creatures must succeed on a DC 18 Strength or Dexterity saving throw (target's choice) or be knocked prone and take 28 (4d10+6) bludgeoning damage plus 28 (4d10+6) slashing damage. On a successful save, the creature only takes half damage, isn't knocked prone, and is pushed 5 ft. out of the cruorhulk's space into an unoccupied space of the creature's choice. If no unoccupied space is within range, the creature instead falls prone in the cruorhulk's space.
