Path of Tremors

Gravel Tenacity

Starting at 3rd level when you choose this path, your durability rivals that of the earth. When you enter your rage, you gain temporary hit points equal to half your barbarian level + your Constitution modifier (a minimum of 1 temporary hit point). You can use your action to regain these temporary hit points. Using your action for this purpose doesn't end your rage if you haven't attacked or taken damage. You can also double your Rage Damage to attacks that deal bludgeoning damage.

Rooting Sense

Starting at 3rd level, your Danger Sense ability applies to saving throws involving Strength as well as Dexterity. In addition, you ignore difficult terrain made from dirt, rock and mud, and can speak, read and write Primordial.

Mineral Meteor

Beginning at 6th level, your strength and influence over the ground increase. You can use your action to rip a Medium chunk of earth out of a space within 5 feet of you made of rock, dirt or stone. You are proficient with this mass of earth, and it has a thrown range of 30/120. Its damage dice is a d6, and the number of dice you roll is equal to your Strength modifier (a minimum of 1d6). This damage increases by 2d6 if you are raging. You can use your action to throw this chunk and make an attack against an object or creature within its range. On a hit, the target and every object or creature within 5 feet of it takes the hunk's damage. This attack deals double damage to objects and structures.   You can use this ability a number of times equal to your Strength modifier (a minimum of once.), regaining all uses upon finishing a long rest.

Boulder Soul

At 10th level you gain the following benefits:

• When you are prone you gain tremorsense for 30 feet.
• You learn the mold earth cantrip.
• You can sense the presence of metals and gems within 120 feet of you, and can estimate the value of items containing metal or gems.

Bedrock Forces

At 14th level, your can command the earth itself to serve you. When you start raging, you can choose to summon two earth elementals to fight alongside you. They follow your verbal commands and last until destroyed or until your rage ends. The statistics for earth elementals are in the Monster Manual.   Once you use this ability, you can't do so again until you finish a long rest.   In addition, your appearance becomes closer to that of rock, whether growing moss on your skin or it turning to the colour of stone. Your AC cannot drop below 17.
