A person that wants to take an advantage in the game for being stronger, or having strong friends. Usually this is done by threatening weaker players with the fact that the power abuser(s) will kill them if they don't do what they say. Or alternatively, another way is to trap a player with monsters while Healing the monster until the player dies on Optional PvP worlds or on Open PvP without getting an unjustified kill. Power abusers are also known with abbrevation PA (PA also means premium account). They are commonly found on PvP worlds.
