Wondrous Item, legendary (requires attunement by a Must have attached and attune over an hour of rest time.)

Spell casting when using this arms mechanics to cast a spell must follow the Alchemical Technology Automated Prosthesis' (ATAP) alchemy spell creation system. The ATAP Does not give the user spells or a casting modifier, the user must learn or know the spells they intend to cast for this arm is a supplement to casters. The ATAP acts as a spell casting focus.

Loading Ore or a Gemstone uses the firearm loading property. Gemstone and Ore slots are not interchangeable.

Ore system in first prosthesis slot:
- At level 1 only 1 slot is available for ore insertion
- At level 10 the prosthesis unlocks, giving 2 total slots for ore insertion
- Ore inserted only needs to be a short rod or scrap
- Ores have a value that equates to the number of spell slots you possess before needing to reload a new scrap or rod
- At level 2, once all spell slots are expended the loaded ore is melted and absorbed into the arm

Gemstone system in second prosthesis slot:
- At level 1 only 1 slot is available for insertion
- At level 10 the prosthesis unlocks, giving 2 total slots for gemstone insertion
