Doppler Decoction is a Decoction in The Witcher 3: Wild Hunt. Decoctions are special mixtures that Geralt can imbibe to gain various buffs with more substantial effects compared to Potions, placing a greater emphasis on synergy with the player's build and playstyle. These effects have a much longer duration, but they also incur Decoction Toxicity which, unlike Potion Toxicity, does not dissipate over time and remains active for the duration of the Decoction, essentially holding a sizeable chunk of your Toxicity bar and limiting your ability to imbibe other concoctions. Decoctions can be used at any time from the Inventory. By default, they have only 1 charge each but can be replenished by Meditating for at least one hour while possessing one or more units of Alcohol.

Doppler Decoction Attributes in The Witcher 3

The Doppler Decoction has the following properties:

Increases critical hit damage when attacking from behind.
50% Increased damage

Doppler Decoction's effects have a base duration of 1,800, but this can be improved with every single point invested in any Skills in the Alchemy Skill line. The Adaptation skill also specifically improves the duration of all Decoctions up to a maximum of 50%. However, this is generally not a worthwhile skill to invest in as you get more than enough of a duration boost just by investing in any Alchemy skills.

Doppler Decoction Crafting Information in The Witcher 3

Like all Decoctions, the Doppler Decoction can be crafted via Alchemy after finding its Manuscript. Manuscripts can be found randomly in treasure chests, particularly in guarded treasure, but some are also sold by certain Merchants while some formulae can even be learned by reading certain books and notes.

The required ingredients for crafting Doppler Decoction are as follows:

• Dwarven Spirit x 1
• Doppler Mutagen x 1
• Han Fiber x 1
• Longrube x 1

The formula for this Decoction can be learned by reading the book The Bear Legend. There is a copy of this book in the Elven Mage's Laboratory during the quest Wandering in the Dark. 

The manuscript can also be obtained randomly.
