World Item

World Class Items are powerful and legendary items in YGGDRASIL.

Overview
In all of YGGDRASIL, there were only 200 World class items.

Each of them had their own unique ability, and some were powerful enough to destroy the game's balance. Of course, not all of the World class items had such game-breaking abilities. Even so, if a player managed to get hold a World class item, that player's reputation in Yggdrasil would jump to the highest level. Effects of a world class item can be resisted in only two ways : (1) Owning another world class item. (2) Getting special classes.
