Nekker warrior mutagen is an alchemy ingredient in The Witcher 3: Wild Hunt and is used to craft nekker warrior decoction. They act like lesser red mutagens when placed in the diamond-shaped slots in the character panel.
Like all special mutagens they can only be dropped by their corresponding monster, but in this case there's a small catch - monster nest bosses don't count. Any other nekker warrior will do, although the drop rate is a bit low.
Notes[]
- In an undocumented change for Patch 1.08, all mutagen icons were changed. However, there was still a bug for those on Steam and Origin that didn't reflect this and was later fixed in Patch 1.22. Despite this, some may still see the original icons instead, even with a fully patched game.
- A common strategy is to kill off the regular nekkers then run away and save before fighting the nekker warriors alone. Then keep reloading the game until the mutagen drops.
