Alchemy requires formulae and the materials necessary to use them. Once you have both, you can begin crafting the most useful aspects of Geralt’s arsenal! The following sections list both the names of the creations, and the materials necessary to craft them. Notice how with potions, oils, and bombs, to create an improved version of an item, you need to create the previous version first. Those material requirements are listed for your convenience.
Once you have created an alchemy item, it has a limited number of uses before it must be replenished. If you have strong alcohols in your inventory, Geralt will use them when he meditates to restore his stocks of potions, decoctions, oils, and bombs! In other words, loot all the alcohol you can carry (unless it belongs to someone else and is in plain view of the guards… that is if you don’t want a fight on your hands).
