Additional substances

There are three additional substances: albedo, nigredo and rubedo. Any given ingredient may contain only one of these substances. If all ingredients selected to create a potion (and only a potion, not an oil or a bomb) contain the same additional substance, the resulting potion will provide additional benefits.

Albedo is an additional substance which can be used to create a potion. If all ingredients used to create a potion have albedo as an additional substance, it will reduce the toxicity of any potions imbibed after it.

Nigredo is an additional substance which can be used to create a potion. If all ingredients used to create a potion have nigredo as an additional substance, Geralt's chances of hitting opponents increases.

Rubedo is an additional substance which can be used to create a potion. If all ingredients used to create a potion have rubedo as an additional substance, they restore Vitality.

Special Ingredients are items which can be obtained by slaying unique monsters, and occasionally, from plants. These can be used to create unique potions with powerful effects (often granting additional talents to be used to obtain skills, or granting special skills directly).
