Not Receiving Corrupted Essence for Quest Essence of Power

Corrupted Essences or Seething Essences, a container which holds multiple Corrupted Essences, will only drop from a boss as long as all the following are true:

• The quest Emerald Nightmare: Essence of Power is active in your character's quest log when you kill the boss
• The raid boss difficulty is Normal or higher
• Your character is eligible for loot
• Your character did not previously kill that boss on any difficulty, Normal or Higher, since reset this week

If you did loot the boss but did not get a Corrupted Essence, check your character's inventory for Seething Essences. The Postmaster will not send you Essences if you did not loot them from the boss.
