The Paizo Organized Play program strives to provide a fun, engaging, consistent experience at all tables. GMs are required to run Paizo Organized Play adventures as written, but are empowered to make adjustments to suit the table, fix obvious errors or typos, use alternate maps, and ensure all players have the best possible experience.
GMs must allow you to use legal character options and cannot change the mechanics of those options. GMs can change the presentation of adventure elements (reskin) to avoid phobias or otherwise ensure a positive experience for all players, but cannot change the mechanics of those elements.
