We’ve datamined likely increased Raid Boss Defeat thresholds for the weekly Great Vault for Aberrus in Patch 10.1.
Previously, players only needed 2, 4, and 6 raid boss defeats to be eligible for weekly Great Vault – Vault of the Incarnates raid rewards. According to datamining, you’ll now need 3, 5, and 7 raid boss defeats for weekly Great Vault Aberrus, the Shadowed Crucible raid rewards. This is likely due to Aberrus having 9 boss encounters compared to Vault’s 8 encounters.
