Yordles gain different adaptations based on where they have spent most of their lives. But wherever they go, they are sure to tinker and gain proficiency with Tinker's Tools. Choose one environment from the list below and you gain that adaptation.

• Bandle City - Years of scraping together items from junkyards to invent with has taught you how to fix pretty much any non-magical item. Gain the mending spell.

• Piltover - You can spend one hour to craft any item found on the Adventuring Gear table in the Player's Handbook if you have the right materials.

Add twice your proficiency bonus to History checks related to magic items, alchemical objects, or technological devices.

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 clockwork device (AC 5, 1 hp). 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 active at a time.

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

Clockwork Toy. This toy is a clockwork animal, monster, or person, such as a frog, mouse, bird, dragon, or soldier. 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.

Fire Starter. The device produces a miniature flame, which you can use to light a candle, torch, or campfire. Using the device requires your action.

Music Box. When opened, this music box plays a single song at a moderate volume.
The box stops playing when it reaches the song’s end or when it is closed.

Due to their magical nature Yordles usually outlive many other races and can live as long as elves.
