Arveiaturace can move across and climb icy surfaces without needing to make an ability check. Additionally, difficult terrain composed of ice or snow doesn't cost it extra movement.
If Arveiaturace fails a saving throw, it can choose to succeed instead.
Arveiaturace can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.
Melee Attack Roll: +14 to hit, reach 15 ft., one target. Hit: 19 (2d10 + 8) piercing damage plus 9 (2d8) cold damage.
Melee Attack Roll: +14 to hit, reach 10 ft., one target. Hit: 15 (2d6 + 8) slashing damage.
Melee Attack Roll: +14 to hit, reach 20 ft., one target. Hit: 17 (2d8 + 8) bludgeoning damage.
Each creature of Arveiaturace's choice that is within 120 feet of Arveiaturace and aware of it must succeed on a DC 16 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 Arveiaturace's Frightful Presence for the next 24 hours.
Arveiaturace exhales an icy blast in a 90-foot cone. Each creature in that area must make a DC 22 Constitution saving throw, taking 72 (16d8) cold damage on a failed save, or half as much damage on a successful one.
Arveiaturace makes a Wisdom (Perception) check.
Arveiaturace makes a tail attack.
Arveiaturace beats its wings. Each creature within 15 feet of Arveiaturace must succeed on a DC 22 Dexterity saving throw or take 15 (2d6 + 8) bludgeoning damage and be knocked prone. Arveiaturace can then fly up to half its flying speed.
