It's a fantasy role-playing game.

DM: You are Caduceus Clay, a firbolg cleric . You are the member of the famous group of adventurers. Previously, Jester purchases the Dust of Deliciousness, and manages to get 5 gp off because Pumat likes her. As Beau and Caleb leave the group, you and Jester continue on their shopping trip:
 Grace of the Wilds: you follows his nose to an herb shop in the Pentamarket.
DM: Yeah, you would be purchasing proficiencies, the training is what you would be doing. This would be the bulk of your downtime, because it will take a while for you to really get--
Player: I only had a couple other light things I was going to do anyway.
DM: But the full training for this will come to about, I'll say, 200 gold.
Player: I can do that.
DM: And you are now proficient in the herbalism kit.
Player: Actually, I was already proficient in the herbalism kit, I was just specifically looking for the stuff to make the potions.
DM: Oh, I misunderstood! Oh!
Player: No, I got that already. I've never-- Back when I did this they didn't have all this craziness.
DM: I've got you. Well, if that's the case, buying the materials-- You're essentially buying them at half-price. You can make healing potions, but you get to make them at 25 gold apiece, as opposed to 50.
Player: Sure! I'll get-- Let's get 150 gold worth of that, and then probably some cooking spices, too.
DM: Okay, yeah. Cooking spices will run you a gold for the full set.
Player: Oh, so it's 151. Anything else of interest or otherwise? Maybe some good beverages or otherwise there?
DM: You can find a whole bevy of beverages all throughout the Pentamarket.
Player: Yeah, I'll find other stuff otherwise. Other than that I've got diamonds and some-- I'm looking for some general store kind of stuff.
DM: Okay. So at 150 gold, (counting) that's six healing potions that you have the materials to make. But you can spend your downtime during this week to make a few, if you'd like.
Player: Yeah.
DM: That'll put you at about one potion per day of creation. So you can easily take this time to make all six.
Player: Oh, easily.
DM: They're baseline healing potions, level one, but you should be able to do so. Cool. And you made a friend with Jasna Bree!
