I mentioned above that this skill is the first that uses player-specific randomness -- and it might be the only one. The tech is being written with the idea that it might be reused for a few other craft skills, either old ones or new ones. But first I'll see how you like the system! Then we'll play it by ear with regard to future skills.

Brewing hard liquor is slightly different than beer. Since all recipes at all level share the 3x4x5x4 pattern, figuring out recipes at low level enables one to know them at high level too. However, this is not immediate because contrary to beer, materials for recipes that follow the same pattern don't map one to one.
