LevellessAoN is a free Chrome extension developed by zhoekstra. It falls under the category of Browsers, specifically Add-ons & Tools. This extension is designed to adapt all the creatures in Archive of Nethys (AoN) to be levelless, making it easier for Game Masters (GMs) who prefer levelless proficiency.

For GMs who are dissatisfied with the level scaling proficiency in Pathfinder 2nd Edition (P2e) and want to explore levelless proficiency, LevellessAoN provides a convenient solution. With this extension, GMs no longer need to manually calculate the DCs, ACs, attacks, and skill checks of monsters on AoN. LevellessAoN automatically adjusts these values to reflect what they would be without considering the character's level.

Additionally, LevellessAoN offers various options in its menu, allowing GMs to experiment with even weirder options like 1/2 level scaling. This flexibility enables GMs to further customize their gaming experience according to their preferences.

LevellessAoN is a valuable tool for GMs who want to explore levelless proficiency in Pathfinder 2nd Edition. With its easy-to-use interface and automatic adjustments, it simplifies the process of adapting creatures on AoN to be levelless.
