Path of the Frozen Heart

All barbarians are driven by fiery anger inside their souls. However, barbarians who follow the Path of the Frost Heart learn how to channel the anger inside them into cold unforgiving fury. These warriors know how to take the fury of winter and transform it into a potent reservoir of power. They are typically born and raised on harsh freezing cold environments, blessed by ancient spirits of frost with unwavering strength and most are cursed to live their lives into a cold survival on the frozen wilderness.

Frozen Domain

Staring when you choose this path at 3rd level, you gain proficiency in the Survival skill. It costs you no extra movement in moving or climbing in cold and icy terrain.

Cold Ferocity

At 3rd level, you become coated in growths of ice and rime that take damage for you. When you rage and at the start of each of your turns while raging, you gain temporary hit points equal to your proficiency bonus plus your Constitution modifier. While you have these temporary hit points, you gain resistance to cold damage. If you already have cold resistance from another source, you gain resistance to force damage instead.

Permafrost

Beginning at 6th level, the power of the cold embraces your entire being for your benefit but may become your undoing. When you attack using an unarmed strike or a melee weapon, you can deal cold damage in place of any other damage type.

Additionally, when you rage, you can choose to gain immunity to cold damage but in turn you gain vulnerability to fire damage. You can't benefit from sources that give you resistance or immunity to fire while you rage this way.

Flash Freeze

At 10th level, beings that touch your blood receives a chilling surprise. When you take piercing or slashing damage, a creature of your choice that is 10 feet of you must make a Dexterity saving throw or become inflicted with frostbite. While frostbitten, they gain vulnerability to bludgeoning dmg until the end of their turn. If they take fire damage, the effect ends early on the creature.

Walking Avalanche

At 14th level, your grasp over the cold, harsh environments and heart can no longer be moved against your will brings you to greater heights to overwhelm your enemies. You gain the following benefits:

• The temporary hit points you gain from the Cold Ferocity feature increases equal to half your barbarian level.
• You gain immunity to the frightened condition.
• While you are raging, you can use a bonus action to emanate a 30 feet radius zone from you that moves with you for the duration of your rage. When a creature enters the zone for the first time or starts its turn there, you can force it to make a Dexterity saving throw. On a failed save, it can use either an action or a bonus action, not both. Regardless of the creature's abilities or magic items, it can't make more than one melee or ranged attack. This effect lasts until the end of their turn. Once you use this feature, you can't use it again until you finish a long rest.
