Before Yoshida entered the Jade Stoa battlefield to see Byakko, he showed off two new mounts: the mount obtained from the Jade Stoa (Extreme), and the Deathclaw mount obtained via achievement points.

Jade Stoa
As mentioned above, Yoshida showed off some gameplay footage of the new battlefield.

The reward for completing the Jade Stoa (Extreme) is a weapon. We recommend that those who will be challenging the Omega: Sigmascape (Savage) aim for this weapon first, as it should make it that much easier. Byakko is definitely harder than Susano or Lakshmi, but we would like for everyone to give it a shot!
