Multiattack

Hraesvelgr makes one Beak attack and two Talon attacks, or he makes three Fist attacks. Alternatively, he can make three Gale Blast attacks. If two Fist attacks hit one creature, the target must succeed on a DC 19 Constitution saving throw or be stunned until the end of its next turn.

Beak (Roc Form Only)

Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 25 (4d8 + 7) piercing damage.

Fist (Giant Form Only)

Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 20 (3d8 + 7) bludgeoning damage.

Talons (Roc Form Only)

Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 17 (3d6 + 7) slashing damage, and the target is grappled (escape DC 17). Until this grapple ends, the target is restrained. Hraesvelgr has two talons, each of which can grapple only one target.

Gale Blast

Ranged Spell Attack: +11 to hit, range 120 ft., one target. Hit: 14 (2d8 + 5) bludgeoning damage plus 7 (2d6) cold damage.

Swallow (Roc Form Only)

Hraesvelgr makes one Beak attack against a Large or smaller creature he is grappling. If the attack hits, the target is also swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside Hraesvelgr, and it takes 17 (5d6) acid damage at the start of each of Hraesvelgr's turns. Hraesvelgr can have only one creature swallowed at a time.

Sudden Gust (Recharge 5-6)

Hraesvelgr unleashes a powerful gust of wind in a 60-foot line that is 10 feet wide. Each creature in the line must make a DC 19 Strength saving throw. On a failure, a creature takes 63 (18d6) bludgeoning damage and is pushed up to 15 feet away from Hraesvelgr. On a success, a creature takes half the damage and isn't pushed.
