- Aqueous Reliquary
- Binds when picked up
- Use: Combine <9/18/36> Aqueous Reliquary to create the <Essence Upgrade Item>, which can be used to infuse your Heart of Azeroth with <essence>. Item created is based on your current loot specialization.
- Requires Level 50
An Aqueous Reliquary drops from selected bosses of the Eternal Palace and is used to upgrade Essences of the 
[Heart of Azeroth]. Three essences are associated with the reliquary:
[Azeroth's Undying Gift] (tank)
[Vitality Conduit] (healer)
[Condensed Life-Force] (DPS)
Sources[]
Reliquaries drop from the following boss encounters:
| Difficulty | Amount dropped |
|---|---|
| Raid Finder | 1 |
| Normal | 2 |
| Heroic | 7 |
| Mythic | 12 |
Should players kill bosses on multiple difficulties, essences will drop up to the maximum difficulty cleared. For instance, should a player kill the Radiance of Azshara first on Raid Finder, then on Heroic, players will loot one Reliquary in Raid Finder, and then six will drop in Heroic, for a total of seven. Should players instead kill in the reverse order, all seven will drop on the heroic kill, and none will drop on lower difficulty levels.
