The Zu Online team (http://zu.igg.com/ ) is launching a campaign to introduce the refining of epic suits.
According to the introduction on its official website, the way to refine epic suits is through tradeskills, of which the complete steps are listed on the site. While adventuring in Zu Online, every player has the chance to obtain useful gear, gems and other good items. Players can use these materials to improve their weapons and armor and increase their attack and defense.
