Path of the Cave Dweller

You've gained your barbaric strength while dwelling in caves for most of your life. This benefits you in several ways.

Cave Sight

Your eyes have attuned to being the dark caves for so long. You gain 30ft of Darkvision.

Cave Rage

Lots of fighting in the caves has granted you superior fighting ability while enraged. Upon starting your rage, you may choose to enter a cave rage. This grants you 60ft of Darkvision, advantage on perception and athletics checks, and lets you Shove as a bonus action. If you start this rage while not in a cave, gain a level of exhaustion when the rage fizzles out.

Cave Knowledge

Through various trials and tribulation in the caves, you can gain a feat.

Cavern Sensitivity

Due to acclimating to the caves, while in a cave or similar environment, you can't be caught by surprise.

Cavernous Aura

You are now as much a part of the caves as they are a part of you. You can now, as an action, emit an aura that blinds hostile creatures within 30ft of you if they fail a DC 15 Wisdom saving throw.

Demon of the Caverns

While in caves or similar environments, you've attuned to the environment to the point where any hostile creature within 60ft of you must pass a DC 15 Wisdom saving throw on the start of their turn or be frightened. You also gain the ability to use your bonus action to make another attack while in caves.
