Primal Path

Path of the Mustang

The Path of the Mustang is a journey undertaken by those barbarians that seek to transform their rage into silent fury. They strive for a balance between their serenity and their bloodlust, their patience and their fury, their torpor and their passion - stopping at nothing to eliminate their enemies as efficiently and precisely as their bodies will allow them.

In order to facilitate this mode of rage, they harness their anger into arrowtips and the blades of their tomahawks - waiting, with boiling blood, for the perfect moment to strike before hurling their weapons at their foes. Their precision is almost as impressive as their swiftness on the battlefield, having forged special pacts with their riding beasts - treating them as well as any of their brothers-in-arms.

In battle, if you choose to take this path, you gain benefits from using ranged weaponry like bows, javelins, and thrown melee weapons, as well as bonuses while engaging in mounted combat.

Ranged Offensive

Once you take this primal path, at 3rd level, your raged bonus damage now applies to ranged weaponry - including bows and thrown weapons. Plus, your Reckless Attack now gives you advantage on ranged attack rolls.

Mounted Master

At 3rd level, you can take 1 hour of meditation to cast find steed. The beast summoned by this action then becomes your primary mount. If it is killed or lost, you can spend another hour to cast find steed and attain a new mount.

Fostered Fury

Starting at 6th level, your familiarity with riding beasts grant them some of the benefits of an animal companion. Your beast increases its hit point maximum by an amount equivalent to four times your Constiution modifier. In addition, while mounted, its AC becomes equivalent to yours. These bonuses apply to any beast you have summoned using find steed.

In addition, while raged, you now have advantage on Wisdom saving throws.

Battlefield Manueverability

Starting at 10th level, while mounted and raging, your riding beast also benefits from your "Fast Movement" ability, and your beast ignores non-magical difficult terrain.

Additionally, you are bolstered by your experience with your mount. When unmounted, you gain an extra 5 feet of movement.

Brutal Criticals now also count towards ranged attacks.

Whistling Destruction

At 14th level, you can declare - before making a ranged weapon attack - that you want the attack to either knock a Large or smaller target prone or push it ten feet away from you in the opposite direction, given that you hit your target. The target will have to make a Strength saving throw with a DC equal to 8 + your Strength modifier + your proficiency bonus. On a failed save, your chosen effect will occur.
