Crystallized Fel

Crystallized Fel is used to upgrade the player's legendary ring: Sanctus, Sigil of the Unbroken, Thorasus, the Stone Heart of Draenor, Etheralus, the Eternal Reward, Maalus, the Blood Drinker or Nithramus, the All-Seer.

This item drops from Archimonde in on Normal, Heroic and Mythic mode once every week after completing We Don't Need No Library Card. It can also be purchased from Dawn-Seeker Krisek in Tanaan Jungle and Zooti Fizzlefury in Talador for.

It does not drop from the LFR version of the encounter.

• Since Crystallized Fel increases the ring's ilevel by 3, it will take 20 weeks of raiding to fully upgrade the legendary ring if you kill Archimonde every lockout.
• It will take 25,000 Valor to fully upgrade the ring if you do not kill Archimonde at all. Since there is an effective weekly cap of 4875 Valor (depending on which Bonus Event is active), it will take a minimum of 6 weeks to do.
