Given that you're focusing a lot on scrolls as an arcane path, and how a lot of scrolls would be awesome if they were higher level.... just always feel it'd be cool that arcane thieves were better at scrolls than anyone else.

Unlike mages, if you "fail" something like a crimson scourge scroll it's not exactly easy to get another one... whereas a caster can just keep casting it. There's also a lot of neat lower level scrolls that rarely get love.
