Path of the Frozen Tundra

Pushed from their homeland, silver dragon born tribes settled on Rin long ago. The bulk of the tribes settled in the North West Territories. Members of these tribes carried an ability that allowed them to transform the terrain of a battlefield to resemble their homeland. This ability bursts from their bodies when they are in the heat of battle, freezing the ground around them. This ability has become increasingly rare generation to generation. 

The most notable warrior who belonged to this path is named Theogren. Theogren fought in the war against Nallossagryth, the black dragon. Commanding a small group of soldiers, Theogren was able to hold the mountain pass preventing the black dragons' minions from flanking the armies of Red Wall.

Child of the North

Due to your heritage you are immune to cold damage, while raging.

While raging any water within your aura freezes instantly.

Icey Aura

Starting at 3rd level, an aura of frost bursts from you while you rage. This aura extends out to 15 feet and causes the ground around you to become difficult terrain. As a bonus action, on each of your turns you can pick an amount of creatures equal to your proficiency bonus to become ensnared by ice. Each of those creatures must make a Dexterity saving throw to avoid having their speed reduced to 0 until the start of your next turn.

DC = Proficiency bonus + Constitution Bonus + 8

Rime

Beginning at 6th level, a thin layer of ice forms on enemies within your aura. These creatures are unable to perform a multi-attack feature unless they pass a strength saving throw at the start of their turn, as the build up of frost begins to hinder their movements.

DC = Proficiency bonus + Constitution Bonus + 8

Glacial Bulwark

Starting at 10th level, you gain temporary hit points at the start of your turn equal to your barbarian level while raging. 

Tundra

Starting at 14th level, your aura extends to a 30 foot radius.

Additionally when you use your bonus action granted by icy aura those who fail their save become blinded by the frigid wind.

Due to the wind in your aura becoming more potent all ranged attacks made into the aura are at disadvantage.
