Rage of Instincts

3rd level Path of the Finder feature

Beginning at 3rd level, when you enter a rage, you gain temporary hit points equal to your Barbarian level plus your Constitution modifer (minimum of +1) that last until your rage ends. However, you additionally take a -1 penalty to your AC while you're raging.

Critical Specialization

6th level Path of the Finder feature

Beginning at 6th level, your attacks are brutally effective. Whenever you hit with a weapon attack using your Strength modifier and the result of your attack roll exceeds the target's AC by 10 or more, that hit becomes a critical hit.

Mighty Rage

10th level Path of the Finder feature

Beginning at 10th level, you are especially quick to fly into blind anger. When you roll initiative, you can use your reaction to enter a rage.

When you use Mighty Rage to enter a rage, you can attempt a grapple, shove, or one weapon attack that uses your Strength modifier as part of the same reaction.

Devastator

14th level Path of the Finder feature

Beginning at 14th level, your anger-fueled strikes defy reason. While you're raging, your weapon attacks that use your Strength modifier ignore bludgeoning, piercing, and slashing resistance, and treat bludgeoning, piercing, and slashing immunity as resistance instead.

Raging Juggernaut

14th level Path of the Finder feature

Additionally at 14th level, you persevere in the face of fatal odds. While you're raging, when you are subjected to an effect that allows you to make a saving throw to take only half damage, you instead take no damage if you succeed on the saving throw.
