Warning to all players:
The Devs have given a warning that the CVs and CVLs will become key players in doing this Event.

Train up all your CV/CVLs to Kai Ni or to a good amount of level (preferably lv65 or higher). Also if you are lacking in Reppuu or at least Shiden Kai Ni, get them crafted using 20/20/10/90 recipe.
