Definitely messed up with the master IV tomes. Should have had one additional tome that included all the non-specialist crafts and should have indicated in the description or even the name of the current tomes that they were for specialists.

Pointed out already, but there is a new non-specialist CUL craft that gives quite a bit of craft and control which can get you over the minimum required. It won't give CP, but you can't always have everything.
