Nowadays the demand of Private Donate weapons was so high, for example the Blade of the Sun. Many of player are looking for good quality stuffs like +14 - 15 enchant weapons.
And one of the reason why we need to put this kind of stuff in the Item Mall, many of our players are using Mobile to donate a premium point, they don't have a Paypal account to make a Private donation. So, make this thing easy and affordable for the Celestia players.
And i know many of players will donate for this kind of stuff.
Item Mall example.
