Amateur Mechanical Arm

On the inside a complex mechanism sits, consisting of many gears, belts, and screws, with a shimmering purple energy crystal in the center of the bicep. The outside is made up of patches of various unpolished metals in varying states of rust. While this arm is attached, you gain a +1 bonus to the spell attack rolls and the saving throw DCs of your artificer spells. As an action, you can reach out and allow a burst of energy to jump from the arm to a target you can touch. In addition, when you cast the spell shocking grasp through the mechanical arm, it does additional damage equal to your intelligence modifier.
