I use the Yanfly Item Synthesis plug-in. I like it!

I hide recipes in dungeons, and they cost a lot, so players can discover them, and dump excess gold; then they have to find a stove in town (or in a house in the middle of nowhere) to make stuff.
I'm so excited you're continuing to work on Wayfarers! Love the map changes! :D
