Vrock

Demonic Resilience. The vrock is resistant to cold, fire, and lightning damage. In addition, it is immune to poison damage and to the poisoned condition.

Magic Resistance. The vrock has advantage on saves against spells and other magical effects.

Multiattack. The vrock makes one Beak attack and two Talon attacks.

Beak. _Melee Weapon Attack:_ +6 to hit, reach 5 ft., one target. _Hit:_ 12 (2d8+3) piercing damage.

Talon. _Melee Weapon Attack:_ +6 to hit, reach 5 ft., one target. _Hit:_ 14 (2d10+3) slashing damage.

Wing Spores (Recharge 5-6). The vrock shakes a cloud of toxic spores from its wings. Each creature within 15 feet of it must make a DC 15 CON save. On a failure, a creature takes 28 (8d6) poison damage and is poisoned for 1 minute. On a success, a creature takes half the damage and isn't poisoned. While poisoned, a creature takes 3 (1d6) poison damage at the start of each of its turns. A poisoned creature can repeat the save at the end of each of its turns, ending the effect on itself on a success. Emptying a vial of holy water on the poisoned creature also ends the effect on it.

Startling Screech. The vrock emits a horrific screech at one creature it can see within 30 feet of it. The target must succeed on a DC 14 CON save or be able to take either an action or bonus action on its turn, not both, and it can't take reactions.
