Tinker

You have proficiency with tinker's tools. Using those tools, you can spend 1 hour and 10 gp worth of materials to construct a Tiny clockwork device (AC 5, 1 hp), such as a clockwork toy, fire lighter, or music box. The device stops functioning after 24 hours (unless you spend 1 hour repairing it) or when you use your action to dismantle it; at that time, you can reclaim the materials used to create it. You can have up to three such devices active at a time.
