Tinkersmith

The typical artificer is a very meticulous and deliberate crafter. Using the best materials and well researched designs for their infusions, they are known for creating items expertly tuned for reliability.

Others, however, prefer to work at the bleeding edge, constantly developing new modifications and accessories from scavenged materials. The Tinkersmith specializes in the creation of gadgets in addition to their regular infusions. They are driven by an unending tweaking of their devices, completely disassembling and rebuilding each gadget on a nightly basis.

Gadgetcraft

3rd-level Tinkersmith feature 

Whenever you finish a long rest, you can use your tinker's tools to create 2 single use gadgets out of scrap materials. It takes an hour to craft each device

Due to the experimental nature of these devices, whenever you attempt to use one you must succeed on a DC 12 Arcana check or the device fails. If you roll a 1 on this check the gadget unexpectedly explodes, dealing 1d6 force damage to you.

Any gadget you create with this feature lasts until it is used or until the end of your next long rest.

When you reach certain levels in this class, you can make more gadgets at the end of a long rest: three at 5th level and five at 15th level.
