Ninja'd. I already made it a 5 level class with no casting.
That doesn't bother me. This class is supposed to justify 5 lost caster levels. In order to get Specialized Casting, you voluntarily sacrifice the ability to cast miracle, wish, and shades by 20th level, two of which let you cast pretty much any spell you want anyway, and the third lets you basically prepare any conjuration (creation) or conjuration (summoning) spell you want.As for the features themselves, Specialized Casting seems way too good for prepared casters. If I pick, say Conjuration (Creation), suddenly I can spontaneously cast almost as many different spells as a sorcerer-- and that's just in core.
