Magic Resistance. The vrock has advantage on saving throws against spells and other magical effects.
Multiattack. The vrock makes two attacks: one with its beak and one with its talons.
Beak. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) piercing damage.
Talons. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 14 (2d10 + 3) slashing damage.
Spores (Recharge 6). A 15-foot-radius cloud of toxic spores extends out from the vrock. The spores spread around corners. Each creature in that area must succeed on a DC 14 Constitution saving throw or become poisoned. While poisoned in this way, a target takes 5 (1d10) poison damage at the start of each of its turns. A target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Emptying a vial of holy water on the target also ends the effect on it.
Stunning Screech (1/Day). The vrock emits a horrific screech. Each creature within 20 feet of it that can hear it and that isn’t a demon must succeed on a DC 14 Constitution saving throw or be stunned until the end of the vrock’s next turn.
