In case you missed all the goodness that was PaizoCon Online, fear not. Paizo has been working at uploading and sharing all the videos from the show. In this article, they look at the ones for the Secrets of Magic book for Pathfinder.
From the post:
The PaizoCon Online 2021 panels are going up on Youtube, so you can watch them again or see what you missed. You can already watch the Keynote Revelations, Starfinder Galaxy Exploration Manual panels, and PaizoCon Liveplays, Fists of the Ruby Phoenix Adventure Path —and now Pathfinder Secrets of Magic with a bonus interview with the Pathfinder Lead Designer!
