Legendary Actions

Boreas can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. Boreas regains spent legendary actions at the start of its turn.

  • Ice Spear. Boreas makes an ice spear attack.
  • North Wind’s Glare. Boreas freezes a foe with a look. One creature within 60 feet that the avatar of Boreas can see must make a successful DC 19 Constitution saving throw or be petrified until the start of the avatar’s next turn.
  • Whirlwind Movement (Costs 2 Actions). Boreas erupts into an icy whirlwind. Mundane and magical light sources alike within 20 feet are automatically extinguished. Each creature within 20 feet of the avatar must succeed on a DC 21 Dexterity saving throw or take 14 (4d6) cold damage. The avatar can then fly up to half its flying speed.


Rime encrusts the wild, spiky hair and beard of this gaunt, savage-eyed man. He strides with an arrogant swagger, snapping blue eyes regarding those around him as an eagle regards the mouse. He carries a dragon-shaped horn, a spear of ice, and an enchanted longbow that shoots bolts of pure frozen air.

Lord of the North Wind. Known for creating mass destruction and death on a whim, Boreas is a devouring spirit of the north who frequently tampers with the mortal world. His worldly avatar resides in a palace of blue ice and white marble on Thule’s highest peak, and he styles himself lord of all the North. Boreas suffers no disrespect and demands yearly tribute of gold, goods, and horses. He has a deep and abiding hatred of the three other Wind Lords.

Easily Angered. When displeased, he bombards his “subjects” with snow, lightning storms, and gale-force winds, or buries them in avalanches by blowing his greater horn of blasting. When particularly displeased, he sends his various servants to descend upon a tribe or settlement without mercy.
