Wings of the Raven is definitely aimed at high-level players, adding both the Skybreak Spire and Dawn of Khanda Vihar raids. Skybreak is a Naryu fortress where the man who betrayed the Hongmoon School is holed up and protected by several guardians. Meanwhile, Dawn of Khanda Vihar is the home to a corrupted dragon who must be taken down to protect the land.
The update has a couple of other additions as well. The devs have streamlined weapon and accessory evolution while adding a new generation of weapon design on top of the existing pile. PvP players can also take part in the new clan battleground rankings for both Beluga Lagoon and Whirlwind Valley.
