Path of the Deep One

Your body is changed by the deep, terrors that dwell in the dark places of the world. It brings with it alien might, and fear to those who oppose you. Your body contains hidden mutations and extremities that burst forth when you prepare for battle. Your body grows mutated natural weapons to strike and hinder enemies. Progressing further in this class grants you the screeching voice of the deep ones and those who dedicate themselves to this path metamorphose, their bodies becoming almost wholly alien to the point they can physically redirect the magic around them.

Tentacle Strike

Starting when you choose this path at 3rd level, you grow an alien tentacle somewhere on your torso or back. While raging you can use your bonus action to attempt a melee weapon attack with the tentacle growth which deals bludgeoning damage equal to 1d4 plus your Rage damage modifier.

Extremities of the Deep

Beginning at 6th level, you grow another alien tentacle somewhere on your torso or back. While raging you can now use your bonus action to make two tentacle strikes instead of one. In addition you can now grapple two medium sized or smaller creatures simultaneously while using your tentacles.

Deep Screech

Beginning at 10th level, a third tentacle surfaces with your rage. While raging you can now use your bonus action to make three unarmed melee attacks with your tentacles. In addition once per rage you can unleash a shattering scream in a 20-foot cone. Each creature in the area must make a Constitution saving throw. On a failed save, a target takes 3d6 psychic damage plus your Constitution, and Rage damage modifiers. On a successful save, a target takes half as much damage.

The save DC for this attack is 8 + your Constitution modifier + your proficiency bonus.

Magic Reflection

Starting at 14th level, your aberrant physiology allows you to warp and redirect magic. While you are raging, if you make a successful saving throw against a spell, or a spell attack misses you, you can choose another creature (including the spellcaster) you can see within 30 feet of you. The spell targets the chosen creature instead of you. If the spell forced a saving throw, the chosen creature makes its own save against the the spellcaster's spell save DC. If the spell was an attack, the attack roll is rerolled by the spellcaster against the chosen creature. This feature cannot reflect area-of-affect spells such as fire ball.

You can use this feature a number of times equal to your Constitution modifier, which you regain after a long rest.
