Path of Stonekin

Barbarians of the Path of Stonekin have a strong connection to the element of earth. You’re endowed with the sturdiness of a mountain and the unyielding strength of stone. Stories about these barbarians claim that the ancient blood of stone giants runs through their veins. Regardless of whether or not it is true, these mighty warriors are capable of unmatched destruction, wreaking havoc upon all those who would dare stand against them.

Might of the Mountain

Starting when you choose this path at 3rd level, whenever you hit with a reckless attack, any melee weapon you wield with the Heavy property increases its damage die by one:
1d8 → 1d10 → 1d12 → 2d6 → 2d8

Immovable Mountain

Additionally at 3rd level, whenever you’re pushed, shoved, knocked prone, or otherwise moved against your will by a creature large or smaller, you can use your reaction to instead move no distance. This feature doesn’t work against teleportation effects or banishment.
At 10th level the size of the creature you resist increases to huge or smaller.

Stone Hurl

Beginning at 6th level, you’ve learnt how to throw large stones as devastating projectiles. While wielding a stone in one hand, using the attack action you can hurl the stone as a ranged weapon attack against a target within 60 feet of you. You can use Extra attack to hurl a second stone, providing a second stone is within your reach, or carried. You can carry a number of stones equal to your Strength modifier.
Each hurled stone deals 1d10 bludgeoning damage on a successful hit. If the target is a medium-sized creature or smaller, it must succeed on a Strength saving throw (DC 8 + proficiency bonus + Strength modifier) or be knocked prone. The attack uses your Strength modifier for its attack and damage rolls, and you can add your rage damage bonus to the attack’s damage if you’re raging.
At 10th level the damage of the attack is considered magical, and increases to 2d10, and 3d10 feet at 14th level.

 

Stone Sense

Beginning at 10th level, your connection to earth and stone grows stronger. You ignore difficult terrain made from earth, stone, or mud. In addition, while you are in contact with solid ground you gain tremorsense up to 30 feet.
The range of your tremorsense improves to 60 feet at 14th level.

 

Stone Fury

At 14th level, your fury seeps into the ground creating an upheaval of earth. You can use your action to smash the ground with your fist or a weapon, sending a line of displaced earth 100 feet long and 5 feet wide in a direction you choose. Each creature in the line must make a Dexterity saving throw (DC 8 + proficiency bonus + Constitution modifier). A creature takes 3d10 bludgeoning damage and is knocked prone on a failed save, or half damage and is not knocked prone on a successful one .
You can use this feature a number of times equal to your proficiency bonus, and regain all expended uses when you finish a long rest.
