Alchemy: fewest-slot mixtures
Steam 1.011. Rune reference reviewed .
8 formulas need 1 slot in their shortest rune match; 14 formulas need 2 slots in their shortest rune match; 7 formulas need 3 slots in their shortest rune match within this 35-ingredient set. The table counts occupied ingredient slots, rather than distinct ingredient names or finished products.
One shortest mixture per formula
Each example matches red, green and blue exactly. Equal-length alternatives are ordered by fewer distinct reagents, then ingredient ID; this order does not rank their gathering cost. Follow a product for alternatives or open its prefilled solver.
Slot limits and station access
Laboratory I provides two slots; Laboratory II provides three. The shortest Reanimation Liquid match in this set uses three slots. Copper Nugget plus two Night Flowers supplies its 2 red, 1 green and 4 blue runes.
A calculated rune match is separate from the product’s station and technology requirements. Organs and powders are excluded from the 35-reagent set; adding them can change the minimum. These results do not establish the cheapest full-game recipe.
How mixtures are compared
The calculation enumerates every combination of one, two or three included reagents, allowing repeated ingredients. It keeps a combination only when all three rune totals equal the product and selects the smallest slot count. Changing ingredient order does not create a second mathematical combination.
