The update also includes a 10-man instance named the Drowned Halls as well as one of the biggest gameplay additions: open world PvP rifts. The Warfront of Whitefall Steppes will feature an alternate "Escalation" mission where combatants must race to charge their side's cannon with sourcestone shards issuing from an Air Rift.
Some of the other additions include quest item keyring that save space in the players inventory with an extra bag specially for quest items, new rare materials, new crafted item sets, and player-crafted augments.
