Path of the Mineral Warrior

All barbarians harbor a fury within. Their rage grants them superior strength, durability, and speed. Barbarians who follow the Path of the Mineral Warrior learn to infuse that rage with the  primal energies of elemental earth, becoming champions with the might of earth and stone. This path is particularly popular with the likes of goliath, earth genasi, and some dwarves. The typical member of this path, especially while raging, looked like petrified versions of themselves, but this had no effect on their agility. Eventually their skin became tougher to such an extreme that some claim even when an opponent managed to effectively hit a mineral warrior, it was hard to hurt them, unless they used an adamantine weapons.

For effects that require a saving throw, the DC equals 8 + your proficiency bonus + your Constitution modifier.
