This guide covers Legendary Recipes, one of the key progression tasks in Potion Craft.
It explains the key points for crafting everything from Nigredo to the Philosopher’s Stone, as well as their uses. Use this guide to help with your playthrough.
Purchasing Parts for the Advanced Alchemy Machine
Legendary Recipes and Legendary Substances are crafted using the Advanced Alchemy Machine located in the basement of the alchemist’s house.
The machine is initially broken and cannot be used, but it can be repaired by purchasing parts from fellow alchemists during The Alchemist’s Path: Chapter III.
There is no need to purchase recipes for Legendary Substances. By crafting them sequentially starting from the initial Nigredo, additional recipes are gradually unlocked all the way up to the Philosopher’s Stone.
After the initial repair, the Advanced Alchemy Machine requires two further upgrades, which can be quite costly. Be sure to negotiate the price.
Used as Materials for Salts
Legendary Substances crafted in this way are used as materials for Salts, which are essential for brewing high-value potions.
Legendary Substances are also used as materials for higher-tier Legendary Substances. For example, creating Albedo requires Nigredo, and crafting the higher-tier Citrinitas requires Albedo.
In short, Legendary Substances are not something you craft just once and forget.
Even Nigredo alone will likely be crafted around ten times, so it is strongly recommended to save these recipes properly.
In addition, unlocking the talent skill Bulk Brewing allows a percentage of ingredients and Salts to be refunded when using batch brewing (crafting five potions at once), so it is worth unlocking this skill in advance.
Recipes up to Rubedo are relatively manageable, but crafting the Philosopher’s Stone requires significantly more effort.

should be made on the Oil Map.
The others can be made on the Water Map, but once you obtain the Wine Map later, the recipes can be further optimized.
About Saving Recipes
Legendary Substances and Salts, like regular potions, can have their recipe pages saved after crafting. Once saved, they can be produced instantly from the recipe book with a single button press, which is very convenient.
However, there are several important points to be aware of, which are explained below.
Legendary Recipes Retain Ingredient Costs
Legendary Substances and Salts retain the total amount of Primary Ingredients used when they were originally crafted.
For example, if a Nigredo recipe was created using a large number of materials early in the game, generating that recipe later from the Recipe Book will consume the same amount again.
As progression continues and more efficient routes become available, Nigredo can often be crafted with far fewer ingredients. Updating Legendary recipes based on these optimized versions can greatly reduce long-term material usage.
Rebuilding every recipe regularly can be tedious, so this is entirely optional and depends on personal playstyle.
What Actually Gets Consumed When Crafting
When crafting Legendary Substances or Salts directly from the Recipe Book, only Primary Ingredients—such as herbs, mushrooms, crystals, and salts—are consumed.
Secondary materials like Potions or previously crafted Legendary Substances are never used, even if they exist in the inventory.
Manual crafting using the Advanced Alchemy Machine can consume these secondary materials, but Recipe Book crafting always prioritizes raw ingredients.
In short, secondary materials do not need to be prepared in advance when generating Legendary items from saved recipes.
In practice, the most comfortable timing to revisit Legendary Substance and Salt recipes is after completing the Philosopher’s Stone.
Recipe Book crafting is extremely convenient, so there is no need to avoid saving recipes early on.
However, refining these recipes later can dramatically reduce resource costs—and once everything clicks, it opens the door to a truly frenzied alchemist lifestyle, where materials overflow and experimentation never stops.
