Aside from the whole cantrip discussion, this is nice to see. Seems like scrolls don't have set prices but are instead the "rarity" thing that still makes no sense, other than the general idea of how often you see it. Was there a "rough" price list per rarity somewhere?
Also nice that scrolls can explicitly be copied into spellbooks - which, I mean, duh - but the whole idea that you have to make a check to succeed or the scroll is wasted?!?! BLEH! I could also see making a wizard make a check to copy a scroll that was a higher level than they could cast - but on the other hand, who would do that? Once in your book you can't cast it anyway, and the obvious solution is to just wait until you can and then copy it. But still forcing a roll to copy a scroll when you can copy another spellbook for no roll? That's definitely getting ignored.
Also it doesn't specifically say that copying a scroll costs anything, although it implies it by the comparison to copying spellbooks.
Overall this could be more clear and less punishing to wizards.
