While looking through the GM Core, I noticed that in the Automatic Bonus Progression, for Ability Apex, it mentions changing the Attribute Score to 18. This is a hold-over from the Ability Score of pre-remaster.
I assume the proper text should now be "choose one attribute score to either increase by 1 or increase to +4 (whichever grants the higher score)."

My 5e DM just asked if I can share the CRB PDF with him since Archives of Nethys is a hard digest for him.
I don't want to violate copyright, but if I were to add the PDF to a FoundryVTT Journal Entry without him having access to the actual file (can only view the PDF, not share), would that be fine?
Is there another solution?
I want to clarify that I am not asking a question about enforceability or morality, just if it's legal within US copyright law.
Also, we don't meet in person. He lives on a different continent right now, and the rest of the group besides one live on the other side of the US.
