Pilot

Pilots are both highly gifted combatants and exceptionally brilliant engineers, combining these two talents to become an unstopplable force on the battlefield. There are as many Mechs as there are Pilots, showing their uniqueness in blending fighting with building. Some Pilots opt to be nible infiltrators that can enter and exit scenarios in the blink of an eye, while others opt to be mobile weapons platforms that blast away everything in sight.

Tool Proficiency

When you adopt this specialization at 3rd level, you gain proficiency with smith's tools. If you already have this proficiency, you gain proficiency with one other type of artisan's tools of your choice.

Create Mech

Beginning at 3rd level, you can summon a mechanized battle suit known as Mech. This Mech resides in the Workshop until you summon or dismiss it with an action. While the Mech is within 5 feet of you, you can use a bonus action to enter or exit it. When first summoned, the Mech appears with hit points equal to your intelligence modifier plus 5 times your Artificer level. The Mech has the following characteristics:

• The Mech’s size is large, and when piloting it, you use this size.
• The Mech is immune to psychic damage, poison damage, and all conditions.
• The Mech has an AC equal to 13 + your intelligence modifier.
• The Mech has a walking speed of 30ft. While inside the Mech this is the only movement option you can use, unless movement modifications are taken.
• The Mech has a Strength score equal to your Intelligence score, which can be used to make any attack rolls, checks, and saving throws which require it.
• While piloting the Mech, the Mech takes damage of types which are not psychic, which you instead take directly.
• The Mech has 4 appendages:
• 2 limbs, which by default have an unarmed strike and a ranged strike
• Unarmed strike: Roll a melee attack using your intelligence modifier. On a hit, deal 1d12 bludgeoning damage.
• Ranged strike: Roll a ranged spell attack (80/320). On a hit, deal 1d10 piercing damage.
• 2 shoulder mounts
• The Mech has disadvantage on stealth checks.

If the Mech is reduced to 0 hit points, it is destroyed. When the Mech is destroyed, you can use your reaction to perform an emergency eject, landing 10 feet away from the Mech in a random direction, and are knocked prone. If you do not eject, you take 3d6 fire damage and 3d6 bludgeoning damage, are pushed 10 feet away from the Mech in a random direction, and are knocked prone.

The Workshop

Beginning at 3rd level, you gain access to a pocket dimension which you can use to work on your Mech, which is only accessible to you. You can access this space during a long rest. Time does not pass in this space and you have no need to eat, drink, or sleep while staying here. In addition, all the materials and tools needed for your work are supplied, but cannot be taken out of the Workshop. While there, you can work on your Mech by repairing it if destroyed, changing its modifications, or altering its appearance. 

Modifications

Beginning at 3rd level, you can modify your Mech by expending artificer infusions. The list of infusions can be found here. Each modification costs one artificer infusion.

Extra Attack

At 5th level, you can attack twice instead of once whenever you make an unmodified unarmed strike or ranged attack.

Onboard Artificial Intelligence

At 9th level, your Mech has some degree of autonomy. While outside your Mech, it remains active and friendly to you, sharing your turn in initiative. While unmanned, it can only move and make one unmodified unarmed or ranged strike against a creature you can designate with a free action.

Overclock

At 15th level, you can push your Mech to the absolute extreme for a short burst of unrivaled power. At the start of this turn you can activate this feature as a free action. For the rest of your turn, your movement speed is doubled and you gain an additional action on your turn. Once you use this feature, you can't use it again until you finish a short or long rest.
