Item Mall. The item mall is a shop you can enter by pressing "F10".
Here you can buy special items such as pets and gold tickets using silk.
Silk is the virtual currency you can buy using PayPal or Click and buy or other methods.
I'll go through the basic items.
You have Expendables which are Tickets, Gender switch tools and global chatting and many more.
They are basically self explanatory just highlight them and read what it has to say.
You can buy pets here and different alchemy items. You can Buy bags of potions or Quivers of arrows.
You can buy a white wolf and pets also Global Chatting which is that yellow writing which everyone
can see in the server. The Item Mall is useful for the advanced player.
