Not all the recipes in Masterbook IV are Specialist. There's still some reason to get them all. For example, Camphor in ALC IV is used in the LTW 3* mat. Everyone assumes they need an ALC specialist to make Camphor for them, but if you look closely it's not a specialist recipe.

Best thing I can keep telling everyone is to start using your red scrips to collect crafter souls and you'll be okay.
