The Witcher
Albedo is an additional, or secondary substance which is present in some alchemical ingredients in addition to the primary substance. All alchemical ingredients contain one of six basic substances: aether, hydragenum, quebrith, rebis, vermilion, and vitriol. There are also three additional substances: albedo, nigredo, and rubedo. Any given ingredient may contain only a single basic substance and potentially one additional, or secondary substance.
Albedo potions: If all ingredients used to create a given potion contain albedo as an additional substance, the created potion and any subsequently imbibed potions for 1 hour have reduced toxicity by 1 scale. Meaning if the potion has High toxicity it is reduced to Medium toxicity. Potions with Low toxicity like Cat and Wives' Tears become Non-toxic just like White Honey.
The Witcher 3: Wild Hunt
Unlike previous games, Albedo is not simply part of other alchemical ingredients. It is needed to craft the following items:
In the base game it must be crafted, but in the Blood and Wine expansion it can also be purchased from alchemists:
- Merchant at the Perfumery
- Wine Merchant at Chuchote Cave, after completing his quest
- Wine Merchant at Dun Tynne Hillside, after completing his quest
Trivia
- In alchemy, the albedo means "purification" of the matter, and is the second step Magnum opus process.
