Method for granting skills for equipment items in online role playing game

The present invention relates to an online role playing game, wherein equipment items of a user character can contain various skills according to a user's selection. Users obtain equipment items that have empty sockets, and then the users mount various skills on the empty sockets of the equipment items depending on what the users want. Thus, the users of the online role playing game can possess equipment items having skills differing from those of others and unique to the users. Even though an equipment item is low in value and has few capabilities, the equipment item can show a sufficiently high level of performance according to the skills mounted thereon whereby discarded equipment items can be minimized and each equipment item can perform a respective role, thereby providing a balanced game instead of a game which is biased toward a particular item.
