Path of Heart

For barbarians, their anger is always just below the surface of their nigh impenetrable skin. For these kind-hearted souls, it lies deeper, yet is awoken far easier. The Path of Heart is a path of compassion, seeking to defend those you hold dear by striking first and standing your ground. Or failing that, viciously avenging what you have lost.

Protective Instincts

Starting when you choose this path at 3rd level, you can seek retribution for your allies pain. Whenever an allied creature that you can see falls to 0 hit points, you may rage as a reaction, and damage dealt to allied creatures can maintain your rage as if you were dealt damage. In addition, while you are raging, if at least one allied creature that you can see is grappled, incapacitated, restrained, or unconscious, you may make a melee attack as a bonus action once every round.

Hearth's Fire

Beginning at 6th level, your compassion envelopes your allies and enemies alike. While you are raging, whenever a creature starts its turn within 5 feet of you if it is allied it gains temporary hit points equal to your Charisma modifier +1. If it is hostile, it takes fire damage equal to your Charisma modifier +1.

This addition increases to +2 at 10th level and +3 at 14th level.

Availing Avenger

Beginning at 10th level, you can use your action to terrify and invigorate those around you with your passion. When you do so, all hostile creatures within 30 feet that can hear you must make a Wisdom saving throw (DC equal to 8 + your proficiency bonus + your Charisma modifier) or take 3d6 psychic damage. All friendly creatures of your choice that can hear you regain hit points equal to half the damage dealt, rounded down. If an allied humanoid you can see is brought down to 0 hit points by a hostile enemy you can use this as a reaction instead of an action.

Once you use this feature you can't use it again until you finish a long rest.

In Good Spirits

Starting at 14th level, use 1 of your Rages to cast Calm Emotions as a bonus action. You may simultaneously enter rage if you are not already raging.
