Barbarian

Class description from D&D Beyond.
Frothing at the mouth, a dwarf slams his helmet into the face of his drow foe, then turns to drive his armored elbow into the gut of another.
Barbarians, different as they might be, are defined by their rage: unbridled, unquenchable, and unthinking fury. More than a mere emotion, their anger is the ferocity of a cornered predator, the unrelenting assault of a storm, the churning turmoil of the sea.   For some, their rage springs from a communion with fierce animal spirits. Others draw from a roiling reservoir of anger at a world full of pain. For every barbarian, rage is a power that fuels not just a battle frenzy but also uncanny reflexes, resilience, and feats of strength.
