Vault of Archavon is a raid dungeon found in Wintergrasp Keep. Players may only enter the dungeon while their faction controls Wintergrasp. Notably, all bosses in this instance grant honorable kills. 10 minutes before the battle for wintergrasp starts, any boss who is not currently in combat turns to stone and cannot be fought again until after the battle is over.
The bosses of the Vault of Archavon drop a random assortment of gear in a similar style as classic World of Warcraft before the expansions. Class specific pieces can drop for both the PvE and PvP sets. The loot can be all PvP, PvE, or a mix of the two. The loot is completely random and is not impacted by the raid makeup, so it is advantageous to bring a variety of class/spec makeups to increase the likelihood that someone can actually use the drops.
It should be noted that the PvP gear cannot be disenchanted but the PvE can. It should also be noted that should a group to wipe, depending on how long it takes to get the group reassembled some members may be flagged for PvP while others are not. This is because the watchers are all PvP flagged, having all members manually flag will prevent members from accidentally not having certain buffs when the fights start.
The "Earth, Wind, and Fire" achievement is currently the most difficult achievement for this instance. Even though it only awards 10 and has no associated title reward, this was intentional according to a Blizzard official.[1]
Patch 3.3.2 (2010-01-02):Toravon, the latest boss to join the Vault's giants and masters of the elements, is now accepting challengers in 10- and 25-player formats.
