War of the Immortals' new expansion is officially live. Perfect World Entertainment is adding a new Harbinger class, the pet ascension system, a new instance called Proof of Divinity, and an extensive PvP revamp with the Lost Omen patch.

This last bit involves "re-tooling the team matchmaking system," PWE says. The changes allow for three teams of up to 180 players to duke it out in a single battle arena (that's 540 players at once if you're counting at home).

There's also a new trailer for the Lost Omen expansion. Check it out by clicking past the cut.
