Foglet mutagen is an alchemy ingredient in The Witcher 3: Wild Hunt and is used to craft foglet decoction. Like all special mutagens they can only be dropped by their corresponding creature. They act like lesser blue mutagens when placed in the diamond-shaped slots in the character panel.
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.
- Any foglet (except Tangalores) can drop it, but the drop rate is pretty low so it's best to save before fighting a lone foglet, then reload until it drops.
