Black Rock Depths Raid Loot GuideWoW's 20th Anniversary Event Overview
Timewarped Relic Coffer Key are a mechanic designed to help players obtain deterministic Blackrock Depths raid loot from vendor. An homage to the dungeon's original mechanic, Relic Coffer Keys work similarly to Puzzling Cartel Dinar from the Fated Season 4 of Shadowlands or Antique Bronze Bullion from the Awakened Season 4 of Dragonflight.
Each main boss from Blackrock Depths drops 3 Relic Keys, while the 5 mini-bosses in the raid drop 1-2 Relic Keys each.
You can only loot 120 Timewarped Relic Coffer Keys total per difficulty.
Each piece of loot costs 40 Relic Keys each, for a total of 3 items per difficulty from the Relic Coffer Vendors.
Loot from Blackrock Depths can be purchased from Relic Vendors in front of the Dark Iron Mole Machine by the celebration area in Tanaris.
