Succubus mutagen is an alchemy ingredient in The Witcher 3: Wild Hunt and is used to craft Succubus decoctions. They act like lesser red mutagens when placed in the diamond-shaped slots in the character panel.
- The player only has two chances to receive this mutagen: during Deadly Delights and during Practicum in Advanced Alchemy when searching for pimpernel. However, if the player leans towards being merciful, they can miss both these chances and must either forego making the decoction, use one playthrough to kill one of the succubi, or use console commands to get the mutagen.
- 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.
