Since the Bestiary is the only resource that a PFS GM is required to have, does that mean that none of the scenarios currently produced refer to creatures in the Bestiary 2/upcoming Bestiary 3 books?
Typically that is the case. Since the writers will not have access generally to those monsters until the bestiary is release. Although if they are on the PRD, I can see B2 creatures being used.
Thanks to everybody who responded. I didn't want to buy Bestiary 2 if I didn't (currently) have to. Now I can spend my money on Ultimate Magic instead. Huzzah!
