Multiattack

The rattok makes three attacks: one with its bite and two with its claws.

Bite

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage plus 3 (1d6) necrotic damage.

Claws

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) slashing damage.

Necrotic Rush (Recharge 5-6)

The rattok unleashes a wave of shadowy versions of itself that fan out and rake dark claws across all creatures within 15 feet. Each creature in that area must make a DC 13 Dexterity saving throw, taking 14 (4d6) necrotic damage on a failed save, or half as much damage on a successful one.
