As the game promised to be as “Free to Play”, you will still be able to play without the use of Item Mall. But as your character has reached such a higher level, you’ll be able to find out the importance of the Item Mall where you could find the materials to gain the abilities of your characters. Most of the items available at the Item Mall are the items that are very useful but at a very low costs. Items use for manufacturing / upgrading your skills, armors and weapons are just exclusively available here.
