Path of Magical Enhancement

Many barbarians let pure anger fuel their rage, while others use the powers of Gods. Barbarians that go down the Path of Magical Enhancement, however, have learned to draw on small amounts of magic from the world, and allow it to alter their form, making them superior than their foes in combat. These barbarians often use their minor magical ability to appear more magical than they really are to the outer world. 

Aura of Elemental Protection

Starting when you choose this path at 3rd level, while you are raging, you emanate an aura 10ft in all directions from you. Allies within the aura (including yourself) become resistant to acid, cold, fire, lightning and thunder damage.

Elemental Attunement

Beginning at 6th level, when you rage you can magically enhance your weapons. You choose one of the following damage types: acid, cold, fire, lightning or thunder damage and can replace your weapons damage with that damage type.

Mirage

Starting at 10th level, you can create illusions to aid you when you aren't raging. You gain the ability to cast Mirror Image, and regain the ability to do so again every short or long rest.

Rage Rush

Starting at 14th level, when raging, you gain the benefits of the haste spell.
