The Witcher 2 Alchemy Guide – Types of Mixtures

You can create three types of mixtures in The Witcher 2 and they are: Potions, oils, and bombs.

Potions

Potions are liquid mixtures that temporarily raise your statistics before combat when you drink them. They can be created by adding special ingredients, such as herbs and monster body parts to an alchemical base such as alcohol.

Potion not only enhance certain senses of the person but also have a side effect associated with them. So, use them carefully or opt for Alchemy development path and reduce the side effect by learning new abilities.

Oils

Oils are blade coatings used before combat that temporarily increase the damage dealt to specific opponents, or increase the chance of causing a critical hit. Good thing is, they have no side effects associated with them.

Bombs

Bombs are range weapons used from distance that can be used to surprise the opponent and stun, incinerate or panic him. The trick lies in timing the use of bomb perfectly to the situation at hand.

Alchemy – Mixture Formulae and Recipes

Before you create a mixture, you should know the correct ingredients you need meaning you would actually need the knowledge of recipes and formulae before you would be able to create mixtures at will in The Witcher 2.

Geralt only knows the basic alchemy knowledge to start with, so he can’t prepare all the mixtures, which are often results of experiments by mages or herbalists. There are three different ways you can acquire these recipes or formulae to create mixtures and they are:
As a reward after completing a quest.
Buy from a shop.
Find as loot.

When you learn a new formula, it will be available in your equipment, journal and the alchemy panel so you can readily create that potion, oil or bomb.

Alchemy Ingredients

Nine natural substances are used when producing potions, oils and bombs. They are: Vitriol, Hydragenum, Rebis, Aether, Quebrith, Vermillion, Caelum, Sol and Fulgur.

These substances are found in alchemical ingredients: herbs and monster body parts – for example in Nekker claws. When you pick up an alchemical ingredient, you’ll be able to check what substance it contains in your equipment and in the alchemy panel.

How to Create Mixtures or Bombs

Enter meditation and then alchemy panel to create a mixture or a bomb. To the left you will see the list of formulae you know; to the right you will see the available ingredients.

The order in which you should mix the alchemical substances is visible at the bottom of the screen. To do so, you can manually add
each substance by scrolling the list to the right, or use the slot auto filling option to automatically fill the central alchemy panel with substances necessary for a given formula.

When you mix the ingredients in the set order, the mixture will be
created and added to your equipment.
