Geralt uses formulas to combine alchemy materials he has on hand into whatever the formula makes. You can obtain formulas for creating potions, bombs, and oils. Most formulas must be purchased, but some can be obtained as loot, and you begin the game with a handful of basic formulas. Formulas can be used to craft items whenever Geralt can successfully meditate, so you can usually make whatever you need on the fly. Note that you must have a formula physically in your inventory in order to craft from it.
