Way of Scrap

Your body is a machine, a weapon. You have learned to modify your body with mechanical parts. 

Robotic Body

Magic Deflection. Your deflect missile ability also works against Ranged Spell Attacks.

Magic Generator. You have a generator inside you that is capable of imbuing your unarmed attacks with raw magic. Whenever you make an unarmed attack you can change the damage type to force damage 

Detachable Limbs. Each of your limbs have a 15ft chain attached to the inside, giving you a reach of 15ft.

Raw Magic Discharge

You can discharge raw magic your body has generated. When you take the Attack action on your turn, you can replace one of the attacks with a beam of concentrated magic that is 35-ft long and 5-ft wide or a blast of unrefined magic in a 10-ft radius around you (your choice). The damage type is force . Each creature in that area must make a Dexterity saving throw against your ki save DC, taking damage of the chosen type equal to 2d10 + your wisdom modifier on a failed save and be pushed back 10 feet, or half as much damage on a successful one and not be pushed back.

At 11th level, the damage of this feature increases by 1d10.

You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest. While you have no uses available, you can spend 3 ki points to use this feature again.

Optimized Body

You optimize your body to be more efficient than ever. An extra set of arms has been attached to your body allowing you to use flurry of blows without expending ki points. Additionally when you stunning strike you can use 1-3 extra ki points to increase the save DC by 2 per extra ki point. As a bonus action you can also spend 1 ki point to cast magic missile at 3rd level. 

Overdrive

You are able to absorb magic from the air around you, causing your body to be overloaded with magic. As a bonus action you can overcharge your body causing the raw magic inside you to surge for 1 minute. For the duration, you gain one of the following effects:

Warp. Every time you take a step you are teleported a couple feet forward. Your walking speed is replaced with a warp allowing you to move through obstacles or straight up in the air a distance equal to your walking speed.

Repelling Strikes. Your fist create magic shockwaves on each strike. Whenever you land an unarmed strike on a creature, the creature is pushed back 5 feet.

Barrier. A thin, semi-transparent barrier forms around you. At the start of each of your turns you gain 10 temporary hit-points.

Refined Core

The magic inside you becomes refined and you gain the ability to control it to its full extent. Whenever you use your overdrive feature you can spend 3 extra ki points to activate all the affects. For 1 minute you gain all of the following benefits:

Warp. Every time you take a step you are teleported a couple feet forward. Your walking speed is replaced with a warp allowing you to move through obstacles or straight up in the air a distance equal to double your walking speed.

Repelling Strikes. Your fist create magic shockwaves on each strike. Whenever you land an unarmed strike on a creature, the creature is pushed back 10 feet.

Barrier. A thin, semi-transparent barrier forms around you. At the start of each of your turns you gain 20 temporary hit-points.

Additionally your unarmed attacks also deal an extra 1d6 of force damage.
