Path of the Stoic

Barbarians who follow the path of the stoic view the world in black and white: that which they can control, and that which they can't. Only the things within their control are worth expressing concern for, and all of those things deserve the full extent of their power. Barbarians who follow this path take their martial training as a way of expressing their level of control over their own body, and by extension, the world.

Eliminate the Passions Starting when you choose this path at 3rd level, your rages propel you into a trance where you can clear your mind of unproductive thoughts. When you enter a rage, you can end one effect on yourself that is causing you to be charmed or frightened. You can also use your bonus action to end such an effect while you are raging. Additionally, while raging, you have resistance to psychic damage.

Exert One's Control Beginning at 6th level, you have advantage on ability checks that rely on your Intelligence or Wisdom. Additionally, you gain proficiency in Insight and one other skill from Arcana, History, Nature, or Religion.

Constant Vigilance Also at 6th level, you have resistance to psychic damage even when you're not raging.

Mind Over Matter Starting at 10th level, when you fail a saving throw, you can expend one use of your rage to succeed on the saving throw instead. If you're not raging when you do this, you can choose to enter a rage immediately.

Shielded from Externalities Also at 10th level, you gain immunity to psychic damage.
