Alignment
Gnomish culture also values kindness and harmony. Many culturally gnomish people work to uphold harmonious relations or apply their ingenuity to better their fellows, often as sages, engineers, researchers, scholars, investigators, or inventors. Others take a more personal approach to these values, becoming minstrels, tricksters, wanderers, or fanciful jewelers. Those raised among gnomish society are generally good-hearted, and even the tricksters among them are more playful than vicious.

Whenever you make an Intelligence (History) check related to magic items, alchemical objects, or technological devices, you are considered proficient in the History skill and add double your proficiency bonus to the check, instead of your normal proficiency bonus.

You can speak, read, and write Common and Gnomish. The Gnomish language, which uses the Dwarvish script, is renowned for its technical treatises and its catalogs of knowledge about the natural world.
Tinker
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.
