So, I didn't really research this well, but I was looking for a faust recipe, only to find one for 30k, there were three gran faust recipes though. And of course there were unbounded fausts.
The thing is, is somebody buying up recipes, forcing other players to buy unbinded items for more?
Oooh, that's cool.
It's a gamble, but it might just work.
Of course, there's no stopping people from buying recipes from Basil, but this would seriously choke that influx.
What's more likely is that players have been buying the recipes in order to craft the fausts, unbind them, and then sell them for a profit. It'll probably go back to normal soon enough.
