Boreas’ Chosen

Frozen Blood. A creature that hits the chosen with a melee attack while within 5 feet of it takes 4 (1d8) cold damage.

Ice Runes. The chosen's weapon attacks are magical. When the chosen hits with any weapon, the weapon deals an extra 2d8 cold damage (included in the attack).

Ice Walk. The chosen 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.

Multiattack. Boreas' chosen makes two ice spear attacks.

Spear. Melee or Ranged Weapon Attack: +6 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 6 (1d6 + 3) piercing damage, or 7 (1d8 + 3) piercing damage if used with two hands to make a melee attack, plus 9 (2d8) cold damage.

Breath of the North Wind. (Recharge 5-6). Boreas' chosen exhales freezing breath in a 15-foot cone. Each creature in that area must make a DC 15 Constitution saving throw. On a failure, a creature takes 28 (8d6) cold damage and its speed is reduced by 10 feet until the end of its next turn. On a success, a creature takes half the damage and its speed isn't reduced. A creature that fails the saving throw by 5 or more is petrified in ice until the end of its next turn instead.
