I think what is throwing me off is the consistency.
What is really missing from this entry on the additional resources is "All material from this book is legal for play except as noted below. Some rules elements are legal but function differently in Pathfinder Society Organized Play, as described." as what is included under the APG. I suppose that the order of the beast entry is what is confusing, unless it is PFS intention to have the orders work as archetypes. Without that statement or further clarification it is defiantly not allowed per RAW.

Lazers, not a big deal really........fun adventure, but plasma skellies......are you for reals, they are gross. By gross I mean really pack a whallop.

I am still new to the society so you will have to pardon me if my question sounds dumb. I just got the new Pazio ACG and saw flamboyant arcana under the magus heading on pg 104. Although the Archetypes are legal for play, this is not directly under an archetype (although it does fall within that page range). So is this arcana PFS legal?
