Just be aware that when you “upgrade” to the Majestic Cauldron, the number of items it generates drops down significantly from what you’d get with the Improved Cauldron. You get exactly 8 paper cups and enough of the pouch, pestle & mortar, and (a) cask(s) to create a Vial and a Small Potion.

This might not be a bad thing, because once you’re at that level, customers aren’t asking for that many items that are tied to the cauldrons. SUGGESTION: Just create the vials and sell ’em for purple gems, unless you get that rare customer asking for a cauldron-generated item.

The number in parenthesis represents the number of purple gems, if you decide to sell that item.
