Thank you very much for the quick reply, and especially so for looking into my request. I really do appreciate it :)
As for the wildcard restriction, I hadn't realized there was a limit, thanks for letting me know. I'm curious though, is that a hard coded limit, or something that could be tweaked?
If at all possible, I'd ideally allow the player to combine any 2-4 ingredients, all of which would result in a blank base potion, that would have all traits shared by 2+ ingredients. Being able to restrict players from using duplicate ingredients in the same recipe would be pretty cool too, and building off of the 2+ required traits idea, being able to have a "failed result" item be rewarded if the brew didn't have any traits passed onto it, but unless any of these are fairly quick and easy tweaks, I don't want to overwhelm you with feature requests.
