"Alchemy is potions, more or less exclusively. The basic types are curatives, stimulants, and novelties. They take ingredients and an hour of work, increasing in rarity as you go up, but you can always substitute kisses - ₭10 for the first rank, a factor of ten for each one up. You can sell them to mortals, for the lower ranks, if you convince them it's homeopathy or some nonsense magic they believe in that doesn't really work; they'll believe that anyway so the Veil doesn't care. About two cups of liquid for an effect, but you can condense them to a drop without losing effectiveness, it's just slow."
"First rank is just duplicating mundane effects with an hour of brewing and mana instead of complicated manufacturing and research. Caffeine, painkillers, dyes, that sort of thing. Rank two gets you triple effectiveness, booze with no hangovers, fireworks, and prescription drugs. Rank three, you stop having to do physically plausible things - directly reknit flesh, slowly but without natural healing's limits. Make the mind unable to register pain as unpleasant, not messing with nerves. Put a full night of sleep in a shot glass, though trying that for more than a few days in a row is a bad idea. Oh, and grenade-effect potions, not much use for a serious elementalist but nice. Rank four, any disease up to recent death is fixable. Quadruple your strength or perceptiveness or memory for hours, serious-business love potions, cosmetic surgery in a vial including eagle eyes, feathers, or adorable bunny ears and cottontails. This is the rank where materials start to be genuinely difficult to get, you'd need favor-trading. Which I am quite good at, of course. Up at rank five arch-curatives restore youth and prevent aging, or restore perfect health even to the long-dead with a body to apply it to. Love arch-potions are scary and don't need to be sticking you on a person. Perfect memory editing, or gifting. Full physical reshaping to anything you can describe well enough to hold in mind. But ₭ 100,000 for the materials is usually the easy way at that point, and that's something like a year of mana production once you've grown into your adult mana capacity, ten years at the start."
