- Heart of Azeroth Essence can't be removed from inventory.
- Azerite Essences can't be destroyed or sold to the vendor.
The Azerite Essences that you may have in your inventory after the launch of Shadowlands can't be destroyed or sold to a vendor. The only way to remove these from your bags is to take them, along with your Heart of Azeroth, to the Chamber of Heart in Silithus. While wearing the Heart of Azeroth, use the essence in the Chamber and it will be removed from your inventory.
