Hi, I'm not sure if this has already been asked before but seeing as I couldn't find it by searching the forums I will ask. Where do you find the recipes to upgrade the snarbolax items? The wiki says that you can buy them from Basil but where exactly does he sell them?
You find basil in the clockworks terminals. Basically, at depths 4, 13, and 23, he'll be there, and he sells all of the recipes for boss token equipment. You'll have to fight your way (or skip everything, that works too) up to those depths (the depth determines the star ranking of the recipes you'll find too), and then you can buy it from Basil, IF he has it.
Course, that might take awhile, because he doesn't always have it. Basically, look at the 'Arcade' section of the mission console thingy.
