Augmentor

Through mishap or madness, certain misfortunate artificers face amputation in their studies. For these artificers, the next logical step is to delve into the art of the augmentor. These cybernetic scientists specialize in upgrading their prosthetic limbs in the pursuit of bionic perfection. Credits: u/Grimtendo

Augmentor Spells

Starting at 3rd level, you always have certain spells prepared after you reach particular levels in this class, as shown in the Augmentor Spells table. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.

Augmentor Spells

Artificer Level	Spell
3rd	chaos bolt, magic missile
5th	Aganazzar's scorcher, gust of wind
9th	lightning bolt, vampiric touch
13th	elemental bane, fire shield
17th	antilife shell, arcane hand

Magitech Arm

At 3rd level, you develop an advanced magical prosthetic, known as a Magitech Arm. This mechanical arm permanently replaces one of your own arms. For the purposes of physical manipulation, your magitech arm functions as a free hand normally would.

The arm is considered magical; it can be sensed by spells such as detect magic and your unarmed strikes using this arm are considered magical for the purpose of ignoring immunity and resistances to nonmagical weapon attacks. The arm is also extremely resilient, and minor damages can be repaired via the mending cantrip or by repairing it during a rest.

At the end of a long rest, you can craft additional spare arms, spending 50gp of materials for each arm you create. You can only have a number of magitech arms equal to your Intelligence modifier at one time. If you exceed this limit, the first arm created instantly disappears.

While you have multiple magitech arms in your possession, you may swap your currently equipped arm for another one in your possession as a bonus action.

Bionic Infusions

When you choose this subclass at 3rd level, you gain access to the following additional Artificer Infusions specific to the Augmentor:

• Arcane Buster
• Energy Bracer
• Grapple Beam
• Gunpowder Cannon
• Iron Knuckle
• Motorized Weapon
• Remote Glove
• Sonic Pulse

You may add these infusions (listed at the end of this subclass) to the list of Artificer Infusions that you can learn.

When you reach 8th level in this class, you can create enhanced versions of these infusions when you infuse them. These upgrades are described in each infusion's description, labeled "Upgraded Infusion."

Arcane Engine

Starting at 6th level, when you gain the arcane weapon spell, you may choose your magitech arm as the spell's target. When you do so, you can apply the arcane weapon's effects to any unarmed strikes and cantrip damage you deal using your magitech arm.

Arcane Weapon

1st-level transmutation

Casting Time: 1 bonus action
Range: Self
Components: V, S
Duration: Concentration, up to 1 hour

You channel arcane energy into one simple or martial weapon you're holding, and choose one damage type: acid, cold, fire, lightning, poison, or thunder. Until the spell ends, you deal an extra 1d6 damage of the chosen type to any target you hit with the weapon. If the weapon isn’t magical, it becomes a magic weapon for the spell’s duration.

As a bonus action, you can change the damage type, choosing from the options above.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can maintain your concentration on the spell for up to 8 hours.

Magitech Fuel

At 9th level, you can harness and repurpose the magical energy within your magitech arms.

As an action, you can destroy one magitech arm in your possession. When you do so, it dissolves into a stream of magical energy that flows into you. As part of the same action, you can then immediately cast any one spell that you have prepared without expending a spell slot. The spell must have a casting time of one action, and the spell is cast at its lowest level.

Overclock

At 15th as a bonus action can push your magitech elements to work faster giving you benefits as if the haste spell were cast. This effect lasts for 1 minute or can be ended early as a bonus action and does not stack with similar effects. When this effect ends, your character is stunned for one round as you cool down. After using this ability it can’t be used until you complete a long rest.
