Ashtyrranthor

If Ashtyrranthor fails a saving throw, it can choose to succeed instead.

Ashtyrranthor can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.

Melee Weapon Attack +14 to hit, reach 10 ft., one target. 19 (2d10 + 8) Piercing damage plus 7 (2d6) Fire damage.

Melee Weapon Attack +14 to hit, reach 5 ft., one target. 15 (2d6 + 8) Slashing damage.

Melee Weapon Attack +14 to hit, reach 15 ft., one target. 17 (2d8 + 8) Bludgeoning damage.

Each creature of Ashtyrranthor's choice that is within 120 feet of Ashtyrranthor and aware of it must succeed on a DC 19 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 Ashtyrranthor's Frightful Presence for the next 24 hours.

Ashtyrranthor exhales fire in a 60-foot cone. Each creature in that area must make a DC 21 Dexterity saving throw, taking 63 (18d6) Fire damage on a failed save, or half as much damage on a successful one.

Ashtyrranthor makes a tail attack.

Ashtyrranthor beats its wings. Each creature within 10 feet of Ashtyrranthor must succeed on a DC 22 Dexterity saving throw or take 15 (2d6 + 8) Bludgeoning damage and be knocked Prone. Ashtyrranthor can then fly up to half its flying speed.
