How do Alchemy tokens work? I've it's through alchemy, what does that mean? I know where to buy the tokens and the alchemy supplies but, how do you make it work?

you'll want to visit the alchove in the commerce district of the underground (you need to be wearing a zombie skin to access the alchove), where you will be able to select an alchemy token, then the other component(s) for whatever you wish to create. some things are limited by level; you gain alchemy levels by making more items in the alchove. (you can level up quickly by buying a bunch of cheap tokens and picking just the token to make a random item of that type.) subetalodge has a list of items that can be made there, including the required level and components.

Thank you so much! That's very clear to me and the best anything has explained it. It's solves one of the last mysteries of subeta for me. :)
