Path of the IceBound

Barbarians who follow the Path of the Icebound are forged by the unrelenting might of winter itself. Their rage manifests as a blizzard that freezes the battlefield and chills the hearts of their foes. Whether blessed by an ancient spirit of winter, cursed by an arctic entity, or simply hardened by survival in a frozen wasteland, these barbarians wield the unforgiving cold as a weapon.

When they rage, frost crystallizes across their bodies, icy winds swirl in their wake, and their enemies feel the unyielding bite of the northlands. Icebound barbarians are not only known for their strength, but also their ability to turn the battlefield into a frozen wasteland as an avatar of winter.

Once per active Rage, you can channel the fury of an avalanche into your movement. As part of the movement on your turn, you do not provoke Opportunity Attacks and ignore Difficult Terrian, but you must move at least 15 feet in a straight line.

On a successful save, a creature takes half as much damage. A creature makes this save only once per turn.

To determine the amount of Cold Damage taken, roll a number of d8's equal to your Rage Damage Bonus, and add them together.
