Ooh, I see, thank you! So then, let's say I wanted to craft Alchemist Fire during the delve, for example. I'd then probably need to buy the materials in advance-- so when buying the Alchemist's Supplies now, would I add that 25Gp cost to the base cost of 50Gp? Meaning I'd pay 75Gp now and then have the materials to fix up Alchemist Fire later on (if the rolls bless me omg). Is that how the costs work? Or is the cost something I always pay at the time of crafting?

I'm sorry for the dumb questions omg.
