Dominion Shattered

You unleash the primal storm sleeping beneath your skin. Bones flex. Tendons snap and reknit. Blood thickens to armor. You are no longer fighting to survive — you are fighting to dominate. While active, you gain resistance to all bludgeoning, piercing, and slashing damage, regenerate 10 hit points at the start of each of your turns, have advantage on Strength and Constitution saves, and can make one additional melee weapon attack whenever you take the Attack action. However, you cannot cast spells (other than Juggernaut spells that only target yourself), must move toward or attack a hostile creature every round if one is within reach, and gain 1 level of exhaustion once the spell ends.
