Primal Instincts
Giant Temper
When you use you persistent rage feature, your size changes to large if there is room to accommodate and your attacks deal an additional 1d6 bludgeoning damage for the duration of the rage. Any equipment you are wielding when you activate this primal instinct is immediately dropped unless it can be used by a creature of your new size.
Rage Power: Giant Temper
Starting at 11th level, you can use an action to make a special attack once per rage, a ground smash:
Ground Smash. You immediately jump up to 15 feet to an unoccupied space. When you land, each creature that is one size smaller than you or smaller within 10 feet of you must make a Dexterity saving throw or fall prone and take a number of d6 bludgeoning damage equal to your rage potency. This special attack also damages structures and objects in the area. Structures and objects take double damage from this attack.
