You can imbue yourself with a primal power called Rage, a force that grants you extraordinary might and resilience. You can enter it as a Bonus Action if you aren’t wearing Heavy armor.

You can enter your Rage the number of times shown for your Barbarian level in the Rages column of the Barbarian Features table (currently 2). You regain one expended use when you finish a Short Rest, and you regain all expended uses when you finish a Long Rest.

While active, your Rage follows the rules below.

Damage Resistance. You have Resistance to Bludgeoning, Piercing, and Slashing damage.

Rage Damage. When you make an attack using Strength—with either a weapon or an Unarmed Strike—and deal damage to the target, you gain a bonus to the damage that increases as you gain levels as a Barbarian, as shown in the Rage Damage column of the Barbarian Features table.

Strength Advantage. You have Advantage on Strength checks and Strength saving throws.

No Concentration or Spells. You can’t maintain Concentration, and you can’t cast spells.

Duration. The Rage lasts until the end of your next turn, and it ends early if you don Heavy armor or have the Incapacitated condition. If your Rage is still active on your next turn, you can extend the Rage for another round by doing one of the following:

• Make an attack roll against an enemy.
• Force an enemy to make a saving throw.
• Take a Bonus Action to extend your Rage.

Each time the Rage is extended, it lasts until the end of your next turn. You can maintain a Rage for up to 10 minutes.

While you aren’t wearing any armor, your base Armor Class equals 10 plus your Dexterity and Constitution modifiers. You can use a Shield and still gain this benefit.

You have Resistance to Poison damage. You also have Advantage on saving throws you make to avoid or end the Poisoned condition.

Your Hit Point maximum increases by 1, and it increases by 1 again whenever you gain a level.

As a Bonus Action, you gain &Reference[Tremorsense] with a range of 60 feet for 10 minutes. You must be on a stone surface or touching a stone surface to use this Tremorsense. The stone can be natural or worked. You can use this Bonus Action a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.

Your Hit Point maximum increases by an amount equal to twice your character level when you gain this feat. Whenever you gain a character level thereafter, your Hit Point maximum increases by an additional 2 Hit Points.
