This update includes the PVP Rank Shop, random item appraisal and durability to all Union Shops and a number of fixes and improvements.
The PvP Rank shop is a place for players to spend their PvP rank points on powerful and unique equipment. All the equipment have win requirements in order to wear, that prevents people buying the items off other players without even playing in the PvP Ranked battles.
You will be able to obtain other high level equipment in the near future via non-PvP means, however the special items the PvP Shop offers won't be obtainable anywhere else.
