The Path of the Frozen Sea - 5E Barbarian Subclass

Icebreaker

Starting when you choose this path at 3rd level, your rage surges forth with the strength to sunder the arctic seas. Once on each of your turns while you’re raging, you can force a creature you hit with a melee weapon attack to make a Strength save (DC equal to 8 + your proficiency bonus + your Constitution modifier). Creatures that fail this save are pushed up to 15 feet away from you, cannot take reactions until the start of your next turn, and must spend 2 feet of movement for every 1 foot they move until the start of your next turn.

Frost Walker

At 6th level, you can freeze the surface of a liquid in a 15 foot radius as you move along its surface (no action required), allowing you to move across fluids such as water, acid, mud, snow, quicksand, or lava. Creatures crossing molten lava can still take damage from the heat.

Frozen surfaces that you create this way can be used by other creatures, and disappear after 1 minute. You can also unfreeze any frozen paths that you have created as an action.

In addition, you gain resistance to cold damage.

Northwind's Howl

At 10th level, you can release the power of the Northwind as a bonus action, creating a wall of howling wind which travels with you. This wall is 5 feet thick, up to 50 feet wide, and remains 5 feet in front of you. The wind wall lasts for 1 minute, or until you end it (no action required).

When you create this wind wall, choose a direction. Ranged attacks passing through your chosen side of the wall have disadvantage, and ranged attacks passing through the opposite side have advantage as the wind influences them.

Once you use this feature, you cannot use it again until you finish a long rest.

Polar Vortex

Beginning at 14th level, you can reshape the battlefield in a whirlwind of frost and fury.

As an action, you can force creatures of your choice within 20 feet that you can see to make a Strength save (DC equal to 8 + your proficiency bonus + your Constitution modifier). Creatures that fail the save are forcibly moved into an unoccupied space up to 10 feet towards yourself. Creatures can willingly fail this save.

As part of the same action, you can make a melee weapon attack against any creature that failed the save that was less than 10 feet from you. Hit or miss, those creatures are then shunted to unoccupied spaces of your choice that you can see within 30 feet of yourself.
