Gnomish Player Character Attributes

Here are the attributes, the stats and game-rules for playing a gnomish characgter. Gnomes are Common Adventurers, so they will be well accepted in civilized lands, not looked at as unusual or unduly suspicious.
Gnomes reach maturity at around 60 years, and they can live 400 years or more, sometimes afforded prosthetics and other machines, magical or otherwise, to support them in their old age. They are rarely taller than 3 feet, weighing no more than 45 lbs. or so, classified as "Small." Gnomes all speak Gnomish and regional Common. (+1 Language for point of Intelligence modifying: Elven, Jotun, Goblin, Sylvan, etc.)
For more information and inspiration, please see under "Gnome" in the D and D Players Handbooks, or the Pathfinder 2e Core Rulebook.
