Darkvision. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.
Gnomish Magic Resistance. You have advantage on Intelligence, Wisdom, and Charisma saving throws against spells.
Tinker. You have proficiency with tinker’s tools. You know the Mending and Prestidigitation cantrips. In addition, you can spend 10 minutes casting Prestidigitation to create a Tiny clockwork device (AC 5, 1 HP), such as a toy, a fire starter, or a music box. Casting the Spell in this way consumes 10 gold pieces worth of raw material (string, gears, and the like), which you provide during the casting.
When you create the device, you determine its function by choosing one effect from the spell Prestidigitation; the device produces that effect whenever you or another creature takes a bonus action to touch the device and activate it. If the chosen effect has options within it, you choose one of those options for the device when you create it. For example, if you choose the spell’s ignite-extinguish effect, you determine whether the device ignites or extinguishes fire; the device doesn’t do both.
You can have three such devices in existence at a time, and each one dismantles itself 8 hours after its creation. You can also touch one of your devices and dismantle it as an Action. After a device is dismantled, the 10 gold pieces of materials used to create it can be reclaimed.
