Path of the Marrow Drinker

This subclass focuses reducing incoming damage while punishing enemies for trying to do so. This subclass will make you function like a Tank and relinquish damage for overall better sustainability.

Calcified Rage

at 3rd level When you enter your rage you create bone armor around your skin. You gain temporary hit points equal to your barbarian level + your Constitution modifier. If any of these temporary hit points remain when your rage ends, they are lost.

Barbed Bone

at 3rd level Your protective Bone plate thickens and is able to bounce off incoming damage. When you take damage from a creature while you are raging, you can use your reaction to reduce that amount of damage by 1d4 while dealing damage to the creature for 1D4 piercing damage. This effect increases at 5th, 9th, 13th and 17th level.

Bone plating

At 6th level Your bone armor from calcified rage now encapsulates your full body. You gain a +2 bonus to your AC as long as you are raging. This bonus increases when you reach certain levels in this class, increasing to +3 at 12th level, and +4 at 18th level. You are now immune to poison damage and resistant against lightning damage.

All Consuming

At 10th level You can transfer your calcification to your enemy and hinder them. When you hit a creature while you are raging, you can choose for that creature to make a Dexterity saving throw with a DC equal to 8 + your proficiency bonus + your Constitution modifier. On a failed save, the target is covered in bones and is Restrained. A creature Restrained by the bones can use its action to make a Strength check against the same DC. On a success, it frees itself. You can use this feature only once per rage.

Bone Phalanx

at 14th level Raging makes the tainted blood within you boil. As a bonus action, you can shoot bones out of your body at breakneck speeds at one creature you can see within 15 feet of you while you rage. The target must make a Dexterity saving throw, the DC equals 8 + your proficiency bonus + your Constitution modifier. On a failed save, the target takes 5d8 Piercing damage. The damage increases when you reach certain levels in this class, increasing to 6d8 at 16th level, and 7d8 at 18th level.
