ill leave this as a stub but i am wondering if there is anything you can do to support witchery crafting esp cauldron crafting. or that's completely impossible?

Completely impossible.

Witchery not have any api. So it could be complicated or impossible.
@jaredlll08 (didnt see you post)

yeah i think he was working on an api but whenever that's done who knows. may be possible in the near future thought. i have hope.

Not for 1.7.10 I think.

honestly he doesn't want his mod to be open and he doesn't want people to deobfuscate or reverse engineer his code . is probably really easy but he said that he likes to keep his mod as closed as possible. i think it may never be possible . :/
