Barbarian: Primal Instinct

Your primal instincts benefit both your rage and persistent rage abilities:

•          Rage. When you enter your rage, you can choose one of your primal instinct rage powers and gain the benefit of that rage power for the duration of the rage.

•          Persistent Rage. When you enter your persistent rage, you gain the benefit of all your primal instinct rage powers and one of your primal instinct persistent rage powers.

If any of the primal instinct feature grants you an ability or a spell that calls for a saving throw, the DC is equal to 8 + your rage potency + your proficiency bonus. In addition, any spell you gain with your primal instincts uses your rage potency in place of any spellcasting ability modifiers.

Your rage is powered by primal might.

Persistent Rage Power: Primordial Wrath

When you use your persistent rage feature, you have resistance to acid, cold, fire, lightning, poison and thunder damage until the rage ends.
