Path of the Invincible

Barbarians who follow the Path of the Invincible devote their lives to being as tough physically and mentally as they possibly can.  They include both the most puissant foes of injustice as well as the most relentless avatars of evil.

Unstoppable Rage

Starting when you choose this path at 3rd level, you have resistance to all damage while raging.

Titanium Mind

At 6th level, you can't be charmed or frightened while raging.  If you are charmed or frightened when you enter your rage, the effect is suspended for the duration of the rage.

Unceasing Warrior

Beginning at 10th level, you have advantage on saving throws against being stunned and paralyzed while raging.

Invoke Invincibility

When you reach 14th level, you unlock an inner state that allows you to momentarily become truly unstoppable.  As a reaction when you take damage, are forced to make a saving throw, or are forced make an opposed Strength (Athletics) check as the target of a grapple or shove attempt, you can Invoke Invincibility.  If you do so, until the end of your next turn, you are immune to all damage and succeed on all saving throws and all Strength (Athletics) checks to avoid being grappled or shoved.

Once you use this feature, you can't use it again until you finish a long rest.
