Mechanic

Automation is a key trade of many of the technically minded, but some believe that automation is hindering the abilities of what could be created. Mechanics are fundamentalist creators and proficient pilots who impose wrath using manned machines or mechs.

Unencumbered

You are now proficient with heavy armor. Heavy armor now gives -1 less AC but you may add your dex modifier to a max of 2 to your AC just like medium armor (or 3 if you have medium armor master). Heavy armor also no longer has a strength requirement for you. 

Level 3: Mech Tinkering

Your research and dedication has lended you discrete knowledge on manned weaponry, allowing you to create a large, hearty, and weaponized mech (see the stat block below). You determine the Mech’s appearance and whether it has two legs or four; your choices don’t affect the mech’s game statistics. It counts as a creature for casting spells and it will sit idly with no one inside it. It vanishes if you die.

The Mech in Combat. In combat, the mech only acts if someone is controlling it. Once inside, You can use an action to make it use an action, and you can use a bonus action to make it use a bonus action. 

Restoring or Replacing the mech. You create a new mech after you take a long rest and may replace it once per long rest. You may, as an action, create a new mech after the first mech has died. You can only have one mech active at once. 

Choosing functionality. The mech is equipped with two utility or weaponizing arms that you may choose when you create a new mech. You may have two of the same type of arm. 

Mech arm	Description
Force Balista	Make a ranged spell attack originating from the arm at one creature or object within 120 feet of it. On a hit, the target takes 3d8 Force damage, and if the target is a creature, it is pushed up to 5 feet away from the cannon. The Balista’s damage increases to 4d10 at lvl 9, and 5d12 at level 15.
Flamethrower	The arm blasts fire in a 15-foot Cone. Each creature in that area makes a Dexterity saving throw against your spell save DC, taking 3d8 Fire damage on a failed save or half as much damage on a successful one. Flammable objects in the Cone that aren’t being worn or carried start burning. The Flamethrower’s damage increases to 4d10 at lvl 9, and 5d12 at level 15.
Seeker Missile Launcher	The arm creates 3 missiles that actively seek out a target within 120 feet of it. A missile deals 1d4 + 1 force damage to its target. The missiles all strike simultaneously, and you can direct them to hit one creature or several. The amount of missiles increases to 5 at lvl 9 and 7 at lvl 15.
Deployable Shield	The mech gains an additional +2 to its AC. The bonus increases to +3 at lvl 9, and +4 at lvl 15.
