Charge Mutagenator through monster kills
Adds a recurring greater mutagen reward to ordinary monster hunting after the Blood and Wine progression unlock.
WHERE & HOW TO FARM
Charge Mutagenator through monster kills
Corvo Bianco in Toussaint, after receiving the Mutagenator from Regis in Blood and Wine.
Before you go
- Own Blood and Wine and progress far enough to receive the Mutagenator from Regis.
- Have access to Corvo Bianco and the device.
- Defeat monsters through contracts, routes, or other regular combat.
Farming steps
- Complete the Blood and Wine progression that awards the Mutagenator from Regis.
- Return to Corvo Bianco and locate the device.
- Check its displayed kill charge so you know whether it is ready.
- Continue defeating monsters during contracts and other normal activities until the device reports activation.
- Interact with the charged Mutagenator to claim its greater mutagen.
- Check the color received; treat it as a variable bonus rather than a chosen result.
- Continue your normal monster route to build charge again, then spend the mutagen in a relevant mutation slot.
- Use contracts and monster encounters you already planned to complete; the charge can accumulate alongside other progression.
- Keep track of which greater colors your mutation plan needs, but do not count on the Mutagenator to provide a specific one.
Repeat, collect and use
The device can be charged and activated repeatedly after it is unlocked. Each activation consumes a completed charge, and the reward color is random; the documented threshold is 100 monster kills per charge.
Common mistakes
- Do not look for the device before its Blood and Wine reward has been obtained from Regis.
- Do not stop at a partial charge; wait until the device reports that it is active.
- Do not treat this as a targeted red farm; use Drowned Dead or other chance-based routes when pursuing red specifically.
When to stop or switch
Stop tracking the charge once you have claimed the greater mutagen you need, or continue passively while pursuing other monster objectives.
