Not an Admin, but can answer you nevertheless …
Warcryer does not have CoV nor Magnus. C3 servers do not have 3rd prof change Quests, therefore there is no 3rd prof Skills. But once you reach level 74 and you get yourself some good S grade Gear, then fully buff yourself with buffs, dances and songs, you’ll see there is no need for CoV anyway – your character will be awesome without that buff.
