Path of the Shared Anger

Taking the Path of the Shared Anger enables one to not only grant bonuses to oneself, but to one's allies as well.

Adjacent Bonus

Starting when you choose this path at 3rd level, you can grant your allies strength as well as your own. While raging, all adjacent allies gain +5 movement speed and +2 damage on Strength-based weapon attacks.

Gain for Gain

Beginning at 6th level, you gain bonuses on attacking the enemy of your friend. While raging, you have advantage on attack rolls against creatures engaged with one of your allies. Additionally, your allies have advantage on attacks made against creatures engaged with you.

Distributed Pain

Beginning at 10th level, you can use your reaction to aid an ally in pain. While raging, if an ally within 10 feet of you is hit with an attack, you can use your reaction to half the damage against your ally and receive half the damage yourself. An ally may also use this reaction when you suffer damage in a similar way within 10 feet. Damage caused by this feature cannot be distributed in the same way.

Another Rager

Starting at 14th level, you can grant your allies the same power as you. When you start raging, one ally within 10 feet gains all the bonuses of your rage as well. The ally must remain within 10 feet to retain these bonuses. If you have no ally selected, you can use a bonus action to select one.
