The Warlord

Most Barbarians do not grow old. Those that do recognize that whatever physical strength time has robbed from them, experience fills the gap. These grizzled veterans draw on the years of experience to dishearten foes with calculated displays of savagery and inspire allies with heroic deeds.

Focus

At 3rd level, the nature of your rage has changed from raw anger to a cold focus. While in a Focus state, you cannot attack recklessly, but may not have disadvantage imposed on your melee weapon attacks. You are also immune to the charmed and frightened conditions and may enter a focus state as a reaction.

Additionally, you may use your Wisdom modifier in place of your Dexterity modifier to determine your Armor Class and Initiative rolls, reflecting your knowledge that positioning is half the battle.

Savage Tactician

Beginning at 6th level, you may perform great Deeds by sacrificing all or part of your rage damage bonus when you hit with a melee weapon attack while Focused. If a Deed requires a saving throw, the DC is Equal to 8 + your proficiency bonus + your Wisdom modifier. You may perform any deed you can pay the cost for. You may attempt Deeds only on your turn. If you have the extra attack ability, you may attempt Deeds only on one attack per turn.

Break their Wills

By 10th level, your ferocity has become something truly terrifying. When you slay an enemy, you may use a bonus action to roar a challenge across the battlefield. All hostile creatures within 30 feet must succeed on a Wisdom saving throw against your Deed DC or be frightened of you for 1 minute. A creature affected this way may attempt the saving throw again at the end of its turn. You must complete a long rest before you are able to use this ability again.

Actions, not Words

Others may choose to bandy honeyed words to rouse their cohorts to action. A warrior leads from the front, and lets his actions inspire where words would have failed. Beginning at level 14, whenever an ally witnesses one of your Deeds, they gain temporary hit points and a bonus to their next attack roll or saving throw equal to the cost paid for the Deed.
