Just like in Korea, Europe and North America, Neowiz publishes the game itself in Japan, so we can get a little insight into the CashShop Items that might be available in the English version. The old Korean cash shop was already pretty fair compared to what other F2P games offer but also had some items that helped you progress faster. They have been removed with the Rebuild Version of Bless though.
