Mech Pilot

Mastery of the modern battlefield requires a hybrid approach of technology and magic, and no combat specialist epitomizes this approach better than the Mech Pilot. Armed and armored in an enchanted mobile suit, the battle mech is a flexible weapons platform built to be reconfigurable. This allows it to fit into any tactical situation on evolving battlefields. The Mech Pilot’s bond to their battle mech is critical to their success. The battle mech is attuned to their pilot’s magic, and strong fluctuations of that power source can cause instability, desynchronization, and mission failure. However, a Mech Pilot with mind and mech united can become an unstoppable force.

Battle Mech

3rd-level Mech Pilot feature

At 3rd level, your knowledge of arcane mechanics has allowed you to develop a sophisticated mechanical suit that you pilot into battle meaning, you gain proficiency in Heavy Armor. Over the course of a long rest, you can use your tinker’s tools to create a battle mech, which functions as a magical suit of heavy armor. The armor weighs 200 pounds, which you can ignore while you wear it. The armor can be the target of one of your artificer infusions. You gain one armor once you reach lvl 3, whereas to build the other armors, you would need to buy the components for 1000gp in the local shop (one-time purchase for each armor, stating which armor components are being bought). The armors are listed in the Tactical Assault Array section. You gain the following benefits while wearing the battle mech:

• When you attack with a weapon, you can use your Intelligence modifier, instead of Strength or Dexterity modifier, for the attack and damage rolls.
• You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.
• You gain proficiency with Martial Weapons.

The armor is powered by your magic, and any creature other than you that dons the battle mech receives no benefits and their movement speed becomes 0.

On a failed save, you can push the creature up to 10 feet away from you, and they take 2d8 thunder damage on a failed save or half on a pass. This can be done upto a number of times equal to Proficiency Bonus. This mode’s AC increases by 2 when you reach 5th level. At 9th level, this mode's AC increases by 4.
