Path of Fiendish Might

The Path of the Fiend Heart is a primal compulsion driving the barbarian down a path of power and violence. In battle your fiendish heart fills you with dark will, fueling you with an inhuman strength and a burning rage.

 

Fell Essence

You fiendish spirit imparts upon you the physical traits and resilience of the denizens of the lower planes. At 3rd level when you adopt this path, you gain darkvision to a distance of 60ft. If you already have darkvision, extend the range by 30ft. While you are raging your darkvision manifests as devil's sight, allowing you to see through both normal and magical darkness.

In addition, while raging you have resistance to fire and poison.

Burning Fury

You fiendish anger allows you to call the flames of the lower planes. At 6rd level when you adopt this path, while you are raging you may choose to have your weapon attacks deal additional fire damage, equal to your proficiency bonus.

Weave Warding

Beginning at 10th level, your fiendish nature protects you from harmful magic. You gain magic resistance while raging. In addition, you permanently gain resistances to fire and poison.

Vile Transformation

Starting at 14th level, while you are raging, you are immune to fire and poison. Additionally, when you enter a rage, you may choose one of the following adaptations. It lasts until your rage ends.

• Demonic Wings: Dark, leathery or feathered wings emerge from your back, granting you a flying speed equal to your walking speed.
• Burning Blood: Your blood boils through your veins. You gain resistance to cold. When you are damaged by a melee attack from an attacker within 5ft, they take 3(1d6) fire damage.
• Fangs or Claws: You grow demonic claws or fangs. As a bonus action, you may make an unarmed attack. This attack deals 5 (1d10) damage (plus any applicable bonuses).
