Path of the Invincible

Your rage burns so brightly it makes you untouchable.

Hardened Skin

Starting at 3rd level, while raging and not wearing armor your AC automatically becomes 20.

Untouchable

Starting at level 6, when you take damage while raging, from an opposing creature you may use your reaction, and forgo one of your attacks to half all damage from that enemy for the rest of your turn. This ability works with rage.

Immunity

Starting at 10th level, when you activate rage you may choose one type of damage, gain immunity to it for the rest of you rage. You gain one level of exhaustion at the end of your rage.

Ragnarok

Starting at 14th level, while raging, you take no damage from the nearest hostile creature as long as you can see them. You gain two levels of exhaustion after your rage ends.
