Dangerous Tinker: The gnomes like pretty things, but you like your creations to be a little more dynamic. You have proficiency with artisan'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) that works for 24 hours, or when you use your action to dismantle it. You can have up to three such devices active at one time. You may reclaim the parts used to create the device once it stops functioning, only if it did not explode. When you create a device, choose one of the following options:
Clockwork Toy: This toy is a clockwork tiny construct that is in the form of a creature of your choice. When placed on the ground, the toy moves 5 feet across the ground on each of your turns in a random direction. It makes noises as appropriate to the creature it represents. When it is destroyed roll a d20. On a roll of 20 the object explodes in a sphere of a five foot diameter dealing 1d4 Fire damage.
Fire Starter: The device produces a miniature flame, which you can use to light a candle, torch, or campfire. Using the device requires an action.
Brass Orb: The device is a small brass orb that makes a ticking sound once a small button on the top is pressed. In 1d10 turns after the button at the top is pressed the device explodes in a sphere 5 feet in diameter dealing 1d4 damage to anything within it. If the device is destroyed, nothing happens.
Absolute Fire Proof: To your kind, smoke is the smell of success, fire is the light of creativity, and third degree burns... are still third degree burns, but at least they sting a little less. You have resistance to fire damage.
