As the Vault of the Incarnates raid tier progresses, this week will be the first that most guilds and groups will have the Break a Few Eggs quest completed and therefore be able to activate the raid skip to Broodkeeper Diurna and farm the last two bosses more quickly for Tier set pieces!
Please keep in mind that to unlock the skip you first need to kill Broodkeeper 3 times on the given difficulty to get 3 Shard of the Greatstaff.
If you already have the quest completed, all you need to do to use the Vault of the Incarnates boss skip is defeat Eranog, the first encounter in the raid, and then activate the 2 major runestones floating around the stairs that leads to Diurna by clicking them.
