Stinging Tail. Melee Weapon Attack: +12 to hit, reach 12 ft., one target. Hit: 11 (3d6) poison damage, 16 Constitution saving throw, half damage on successful save.

Fire breath (Recharge 2-4). The abyssal drake exhales fire in a 60-foot cone. Each creature in that area must make a DC 20 Constitution saving throw, taking 35 (10d6) fire damage on a failed save, or half as much damage on a successful one.

Frightful Presence. Each creature of the drake's choice that is within 120 feet of the drake and aware of it must succeed on a DC 17 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the dragon's Frightful Presence for the next 24 hours. Dragons ignore the frightful presence of an abyssal drake, as do other abyssal drakes.

Claw. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) slashing damage

Rend. If an abyssal drake lands a critical hit on an opponent, it latches on to them with both claws and tears the flesh, dealing an additional 4d4 +13 damage.
