Special Traits

• Dive Attack. If the hraesvelger is flying and dives at least 30 feet straight toward a target and then hits it with a talons attack, the attack deals an extra 13 (3d8) damage to the target.
• Flyby. The hraesvelger doesn’t provoke opportunity attacks when it flies out of an enemy’s reach.
• Magic Resistance. The hraesvelger has advantage on saving throws against spells and other magical effects.
• Magic Weapons. The hraesvelger’s weapon attacks are magical.
• Keen Sight. The hraesvelger has advantage on Wisdom (Perception) checks that rely on sight.

Actions

• Multiattack. The hraesvelger makes two attacks: one with its beak and one with its talons.
• Beak. Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 27 (4d8 + 9) piercing damage.
• Talons. Melee Weapon Attack: +15 to hit, reach 5 ft., one target. Hit: 23 (4d6 + 9) slashing damage, and the target is grappled (escape DC 23). Until this grapple ends, the target is restrained, and the hraesvelger can’t use its talons on another target.
• Fling. The hraesvelger tries to throw a Small or Medium creature within 60 feet of it. The target must succeed on a DC 14 Dexterity saving throw or be hurled up to 120 feet horizontally in a direction of the hraesvelger’s choice and land prone, taking 1d8 bludgeoning damage for every 10 feet it was thrown.
• Wind Aura. A magical aura of wind surrounds the hraesvelger. The aura is a 30-foot-radius sphere that lasts as long as the hraesvelger maintains concentration on it (as if concentrating on a spell). While the aura is in effect, the hraesvelger gains a +2 bonus to its AC against ranged weapon attacks, and all open flames within the aura are extinguished unless they are magical.

About

This enormous eagle is so large its wings blot out the sun.

Hraesvelgers are spirits of the wind. Where bergjotnar guard the mountains and grithungur manage the forests, the hraesvelger guards the skies. Summoned only in time of great need when a being of considerable might takes to the air; or an army of winged beings. When roused, hraesvelgers are terrifying to behold, capable of inflicting as much destruction on the land as in the air, wiping entire villages away with their wings.
