From the introduction:
Welcome to the Raiders of Shrieking Peak Resonance Test! This supplemental release tests a new set of rules that could replace the system for Resonance Points used in Pathfinder Playtest: Rulebook. It uses Pathfinder Society Playtest Scenario 2: Raiders of Shrieking Peak, a great adventure written by Luis Loza for the Pathfinder Society Roleplaying Guild campaign, along with adapted versions of the Pathfinder Society’s pre-generated characters, which you can find at the end of this document. Pathfinder Society Roleplaying Guild members can run or play either version of the adventure for credit.
...
The Resonance Point system has consistently been criticized by readers and playtesters for limiting their characters too much. Data from our surveys and comments on social media and forums have also shown this. This test system attempts to let you use items more often and with fewer restrictions, while keeping an echo of the more exciting and interesting themes and particulars, providing you with additional benefits instead of restrictions. Please let us know what you think as you read these rules and play this adventure!
