Augmenteer

While many Artificers seek to improve the world around them, the Augmenteer instead turns inward. Armed with a multitude of gadgets and enhancements build into their flesh, the Augmenteer can adapt to any situation with a quick body modification.

Level 3 Features:

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.

Augmenteer Spells.

You always have certain spells prepared after you reach particular levels in this class, as shown in the Augmenteer Spells table. These spells count as artificer spells for you, but they don't count against the number of artificer spells you prepare.

Test Your Metal.

At 3rd level you first begin to combine your flesh with steel. Your Unarmed Strikes deal 1d6 Bludgeoning damage and you can use your Intelligence Modifier for their attack and damage rolls. You can apply an Infusion to your Unarmed Strikes as if they were a Simple Weapon.
In addition to this you also gain access to a list of experimental infusions called Augments. These infusions are applied to your own body rather than an item, and your body can support up to 6 of these infusions at once. At 3rd, 5th, 9th and 15th level you gain a special Augment infusion slot which can be used to apply any Augment infusion to yourself regardless of whether it is one of your infusions known. Like standard infusions, the Augment used in this slot can be changed at the end of a long rest.

Overdrive.

At 3rd level you learn how to empower your Augments beyond their normal capabilities. You have a pool of Overdrive points equal to the amount of Artificer levels you have, which can be used to activate the Overdrive of any of the Augments you have installed. You regain all lost Overdrive points at the end of a Long Rest.

Level 5 Feature:

Extra Attack.

You can attack twice, rather than once, whenever you take the Attack action on your turn.

Level 9 Feature:

Self Sustained.

Starting at 9th level magitech fully suffuses your body, you no longer longer need to eat, drink, breathe or sleep.

Level 15 Feature:

Catalytic Conversion.

At 15th level you can, as a Bonus Action, expend one spell slot and gain a number of Overdrive points equal to the slot's level.
