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.

Primal Instinct

Gleeful Savagery

Your rage is empowered by brutal savagery.

Rage Power: Gleeful Savagery

Once during your rage, you can make one attack an automatic critical against a creature that is dazed, fatigued, frightened, prone, restrained, or weakened.

Persistent Rage Power: Gleeful Howl

When you use your persistent rage feature, you can attempt to frighten creatures within 60 feet of you with a terrifying howl when you reduce another creature to 0 hit points or score a critical hit. Each creature of your choice that can hear you must make a Wisdom saving throw or become frightened of you until the end of your next turn.
