Path of the Iron Revenant

Your soul is bound by Metal itself, enchanting you with its resilience and endurance.

Darkness Rise

Starting when you choose this path at 3rd level, when raging your body is engulfed in a storm of Magic Metall Shrapnels, that deal damage in a 5 feet radius around you to any creature that starts or ends it turn in the radius.

3rd level, 1d6 slashing damage in a 5 feet radius around you
5th level, 1d6 slashing and piercing damage in a 5 feet radius around you
11th level, 1d6 slashing, piercing and bludgening damage in a 5 feet radius around you
15th level, 1d8 slashing, piercing and bludgening damage in a 5 feet radius around you
20th level, 1d8 slashing, piercing and bludgening damage in a 10 feet radius around you

This changes with level getting +1d6 piercing damage at 5th level,  1d6 bludgening damage 11th level, 15th level all dice become a D8, and at 20th level the radius increase to 10 feet.

Death's Grasp

Beginning at 6th level, you can’t be charmed, frightened, paralyzed and your movement speed does not decrease lower than your racial movement speed while raging. No matter what weapon you use you gain the weapon propertie reach, adds 5 feet to your reach when you attack with it, as well as when determining your reach for opportunity attacks with it.

Indestructible

Beginning at 10th level, your body melts together with an armor. Changing your "Unarmored Defense" to be the AC of your heavy armor of choice +Constitution modifier. (this can't be changed later, Magical Armors keep there effect while morphed with your body)

Obliterate

Starting at 14th level, when you take damage from a creature that is within 10 feet of you, you can use your reaction to make a melee weapon attack against that creature. This effect can be used as much as your STR modifier per round.
