Hello!
A bit of backstory to lead up to my question. I've recently entered the TTRPG hobby since July of 2018 and I've only done DMing for D&D 5E. One of the things that I like about this edition from a DMs perspective is that I can just use the core books (PH, MM, DMG) for any of the adventures WOTC releases without needing other sourcebooks (VGtM, SCAG, etc.) to reference.
My group is getting ready to try out Pathfinder 2E when it releases and we're going to do the Age of Ashes adventure path. I don't know anything about how adventure paths were done in the past for Pathfinder 1E, but for future 2e adventure paths can I just use the Core Rulebook and Bestiary like D&D 5E or would I have to purchase additional sourcebooks?
Thanks!
