Barbarian: Path of the Chieftain

For some barbarians, it is their duty or birthright to lead their tribe and kin to battle and victory. The Path of the Chieftain is forged from alliances, bonds, and strategy. In combat, their rages are less mindless and more focused. Ignoring the distractions of unimportant events, their attention hones in on the battlefield and how best to direct and control it. They guide their allies' strikes, and their presence is enough to wash away their fatigue.

Savage Diplomat

Your path necessitates that you build relationships with others for the betterment of your tribe and yourself. When you choose this path at 3rd level, you gain proficiency in one of the following skills of your choice: Persuasion or Intimidation. You can choose to learn one language in place of this skill proficiency.

Commanding Rage

Also at 3rd level, when in your rage, you become more aware of your allies and their intent when fighting at your side. While you are raging, when an ally within 10ft of you makes an attack roll against a hostile creature, you can use your reaction to add your rage bonus to their attack and damage rolls.

Inspiring Presence

At 6th level, your mere presence on the battlefield rallies your allies. When you rage, choose up to 3 allies within 30ft of you. Each creature gains temporary hit points equal to half your barbarian level (rounded down) + your Charisma modifier (minimum of one).

Raid Planning

Starting at 10th level, you learn to flare up your allies' drive for combat, urging them to follow you into the fray. During a long rest, you tell sagas, sing battle songs, and give inspiring speeches. At the end of the long rest choose up to 5 creatures that can hear and understand you (which can include yourself). For the next 8 hours, these creatures add your Charisma modifier (minimum of one) to their initiative rolls and a 10ft bonus to their movement speed on the first turn of combat.

War Chant

By 14 level, you have memorized the strategies of historic commanders and generals. When you enter a rage you can take a commanding stance. If you do so, for the duration of your rage you have a special reaction you can take on a number of allies' turns equal to your Charisma modifier (minimum of one). You can only use this special reaction to use your Commanding Rage feature.
Additionally, during this rage, when an enemy within 10ft of you makes an attack roll against an ally, you can use your reaction to reduce that roll by an amount equal to your Charisma modifier (minimum of one).
Once you've used this feature, you must complete a long rest before you can use it again.
