Oh, and JeminiZero, instead of giving the Ultimate Scholar a second item creation feat, wouldn't it be better to give the Ultimate Scholar a familiar instead?
I'd change the Scribe Scroll text to the following: "Scribe Scroll: You gain Scribe Scroll as a bonus feat. If you already have Scribe Scroll, you may instead pick one other Item Creation feat of your choice, which you qualify for or the familiar class feature, if you have a prepared arcane caster association".
