Earth elemental mutagen is an alchemy ingredient and is used to craft earth elemental 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.
- There are 2 guarded treasures each in Velen and Skellige guarded by earth elementals. However, they're all higher level monsters than what one would encounter during quests.
