The Frozen

You were born and raised in icy, unforgivable conditions. As such, your body has adapted to the bitter cold. Snow and frost don't faze you. Ice and wind are nothing against your hardened skin. Even the warmth of heat and fire is sapped in your presence. You are The Frozen.

Frostbite

Starting at 3rd level, your skin is covered in an icy sheen, and you gain resistance to cold damage.

Additionally, while raging, any creature within 5 feet of you that hits you with a melee attack suffers 5 cold damage and has disadvantage on their next attack roll against you.

Frost Brand

Starting at 6th level, when you hit a creature with a melee weapon attack, you can mark them. The mark remains for 1 minute, until the creature is incapacitated, or you mark another creature. Only one creature may be marked at a time. While marked, your melee weapon attacks deal an additional 1d8 cold damage to that creature. This damage increases to 2d8 at 10th level, 3d8 at 15th level, and 4d8 at 20th level.

Frost Guard

Starting at 10th level, you have become inured to the heat and cold. You gain immunity to cold damage and resistance to fire damage.

Additionally, you and creatures of your choice within 15 ft. of you ignore difficult terrain caused by ice and snow.

Frozen Gale

Starting at 14th level, a howling blizzard rages in your veins, begging to be released. While raging, you gain a flying speed equal to your walking speed. If your rage ends early and you are still in the air, you float softly to the ground at a rate of 60 feet per round.

Additionally, you can cast the Cone of Cold spell a number of times equal to your Con. modifier, and Constitution is your spellcasting ability modifier for this spell. You regain all expended uses on a long rest.
