GURPS Power-Ups 6: Quirks
This GURPS supplement explores character quirks: minor traits that add personality, color, and complications to adventurers and NPCs. It collects nearly 200 established and new quirks, most with customization options and examples, and offers guidance on what qualifies as a quirk, how quirks affect characters, and how to add, remove, or change them. The material supports ready-to-use traits as well as ideas for developing distinctive characters and inhabitants for game worlds.
