You construct a mech: a suit of piloted armour you can control from within. Your mech is a Large magical object. It has an AC of 16, a number of hit points equal to your Intelligence Score + five times your artificer level, Strength score equal to your Intelligence score. It is immune to poison damage, psychic damage, and all conditions. You can use your mech as a spellcasting focus for your artificer spells.

At the end of your long rest, you can decrease your maximum hit points by an amount equal to your artificer level x your Constitution modifier, if you do your mech gains an amount of temporary hit points equal to the maximum hit points you lost. In addition, you can expend hit dice at the end of a short rest, if you do, you can give your mech an amount of temporary hit points equal to the number rolled + your intelligence modifier. Your mech looses all its temporary hit points at the end of your long rest.

While within 5 feet of you mech, you can use your action to enter it. If your mech isn't within 5 feet of you but is on the same plane of existence, you can use your action to teleport it to an unoccupied space within 5 feet of you and enter it as part of the same action.

While piloting your mech, the following features are applied:

• Your size becomes Large.
• You can use your mechs AC instead of your own.
• Your mech can't be targeted by attacks.
• You can't use any other speeds you have except for your walking speed, unless that speed is granted to you by a spell or magical effect.
• your Strength score changes to the score of your mech unless your strength is greater than your mechs strength.
• Whenever you take damage that isn't psychic, your mech take the damage instead. If this damage reduces the mech to 0 hit points, you don't take the remaining damage.

You can eject from your mech as a bonus action, landing in an unoccupied space you can see within a feet of it equal to your mechs Strength score + your Intelligence score. If your mech is reduced to 0 hit points, you eject, and the mech is destroyed. A destroyed mech can't be piloted, but you can still teleport it to you.

You can spend 1 hour as a part of a short rest repairing your mech using your smith's tools, provided you are within 5 feet of it and you expend a spell slot of 1st level or higher. The mech regains all its hit points, and if it was destroyed, you repair it. At the end of a long rest, you can create a new mech, or repair your existing mech if you have your smith's tools with you. If you already have a mech from this feature and you try to create a new mech, the old one is immediately destroyed.
