Path of the Metallica

Barbarians who goes down the Path of the Metallica gain their rage through the use of metallic prosthetics. These Barbarians learn quickly to take advantage of these prosthetics to become the weapon they themselves may use.

Metallic Prosthetic

At level 3 as a Barbarian of the Metallica you have to specify what type of prosthetic is allowing you to use rage. Each type of prosthetic changes a bit on how your actual rage looks like.

Accelerated Prosthetic

An Accelerated Prosthetic quickens a Barbarians steps and punches while enraged, making them quite a recon to deal with on the battle field.

When Rage has been activated the Barbarian rolls a 1d6 based on the level they currently are divided by 5 rounded up (Level 1-5 = 1d6, Level 6-10 = 2d6, Level 11-15 = 3d6, Level 16-20 = 4d6) and the total roll will be added to next Hit/DC attack the Barbarian does. Also when the Barbarian successfully hits an attack on a target for the first time while enraged the Barbarian will roll a 1d10 and the total number will be added onto their total Speed (1-5 = 5ft, 6-10 = 10ft). After every successful hit the Barbarian does they may choose to re-roll to maybe get a higher number. The extra Speed will last until Rage has worn off.

Reinforced Prosthetic

A Reinforced Prosthetic makes a Barbarian become both stronger for the first swing the Barbarian does but also makes it easier for a Barbarian to tank a hit without worrying about taking damage. 

When Rage is activated the player will roll 1d6 bludgeoning damage for every level the player is but halved, rounded up (Level 3 = 2d6, Level 7 = 4d6, Level 15 = 8d6, etc.) and will add that number as damage for the next attack. At the same time after the first landed attack the Barbarian rolls a 1d4 to see how much is added onto the Barbarians Armor Class, the Barbarian may choose to re-roll the 1d4 after every landed attack if they want to do as such. The added  Armor Class will only last until the Rage wears off.

Upgraded Scraps

Fighting with the same prosthetics for a little while means for an upgrade! At level 6 the Path of the Metallica barbarian gets an upgrade to their respective prosthetic, meaning that they can show more of their metal parts then just while being enraged.

Quicken Overload

Your already Accelerated Prosthetic starts working overtime to help allies nearby, running in front of them to save them from any danger that might be thrown their way. When an ally that is in an 15 ft range from the Barbarian is attacked by an attack that requires a Hit/DC the barbarian can sprint over to take that hit instead as a reaction. Though the distant from the barbarian and it's ally will be removed from the Barbarians speed on their next turn, only coming back on the Barbarians next turn.

Wrecking Knockout

Your Reinforced Prosthetic gets ready to weaken nearby enemies when hit by blows from your allies, knocking them out prone when already taking so many hits. When an enemy that is an 15 ft range of the Barbarian is hit with an attack that requires a Hit/DC the Barbarian can as a reaction force the enemy to do a STR Saving throw (DC = 8 + Strength Modifier + Proficiency Bonus). On a fail the enemy gains the Prone condition and is knocked down. Though on a success the Barbarians reaction reset on the Barbarians second turn.

Passive Gear-Turning

At level 10 the Barbarian of the Metallica's prosthetic starts to become stronger while being enraged, making the passive of each variety of a prosthetic have the potential to be even better then usual.

Rapid Forcers

The Accelerated Prosthetic starts to pump even more speed during combat while enraged, making the Barbarian able to run even faster then usual. The added speed Accelerated Prosthetic gives goes from being a 1d10 roll to instead become a 1d20 roll.

Reinforced Armor

The Reinforced Prosthetic starts to become more durable, making it able to take more hits then usual without any worry. The added armor class Reinforced Prosthetic goes from being a 1d4 roll to instead become a 1d8 roll.

Mechanical Psycho

At level 14 the Barbarian after so many obstacles that have been overcome have finally manage to push enough buttons on their Metallic Prosthetic that they have managed to use their special moves without the need of being enraged and several times too. When Mechanical Psycho is used, the Barbarian is able to use their special move that appears when they start to Rage without needing to be Enraged. Though the passive of each Prosthetic does not come along with Mechanical Psycho. The amount of uses is equal to the Barbarians Proficiency Bonus and resets after a Long Rest.
