Techno-Tinkerer. You have proficiency with artisan's tools (tinker's tools). Using those tools, you can spend 1 hour and 10 gp worth of materials to construct a Tiny high-tech device (AC 5, 1 hp). Construction also includes electrical or photonic components you are assumed to carry on your person. The device ceases to function after 24 hours (unless you spend 1 hour repairing it to keep the device functioning), 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 at a time.

When you create a device, choose one of the following options:

Drone. As an action, you can remotely move this device which has a fly speed of 10 feet (hover). You can only control it if it is within 30 feet of you. If it moves outside this range, it falls softly to the ground. It has a tiny grabber with which it can pick up items weighing less than 1/2 lb.

Noisemaker. When placed on the ground, this device waits for 1 minute and then makes loud beeping and clicking sounds that can be heard up to 90 feet away.

Dreamcatcher. When placed on the forehead of a sleeping creature, this device records the creature's dreams. It can store 1 hour of data. It plays back the dream in a psionic format that only an alien grey can understand.
