Path of the Mechanic

Path of the Mechanic Barbarian is a subclass focused on fighting/damaging/repairing large machinery and other mechanical tech items. The primary damage output of their Code magic is Mechanical Damage, but it can vary depending on what/who they are fighting.

Mechanical Sense

You have studied Mechanical Engineering extensively, and have an intuitive sense on how most modern machinery functions. You gain advantage on insight checks relating to Mechanical based items/constructs, and can gain knowledge from these rolls along the lines of Hit Points, Armor Class, Weaknesses (If Any), Strengths (If Any), how to operate the item/construct, and more. 

Mechanized Rush

Starting at 3rd level, when fighting a Titan or other mechanical construct, immediately after you take the attack action on your turn, you may make two attacks as a bonus action.

Percussive Maintenance

At 6th level you are able to clear your mind enough to focus the anger on one particular issue. By expending one use of your Rage you are able to hit a mechanical object with enough force and precision that it starts to function properly again. Once this machine is operational, you will have advantage on any roll required to make it work for you (In example of convincing an enemy construct to work for you instead of its original owner.)

Tune Up

Starting at 10th level, you have the ability to make minor adjustments to any Code based weapons you are attuned to. Every 2 levels (Starting with your first upgrade at level 10), you may either increase the base damage die by 1 dice level (Max of 1d20), Add another +1 to the item, or choose an additional damage type to add 1d4 of bonus damage to your code weapon.

Rage Against The Machine

At 14th level, while raging, you become a siege monster. You deal double damage to objects and structures.
