Boss - OSRS Wiki

A boss is a powerful, usually unique monster that is fought to accomplish an objective, be it the advancement or completion of a quest or minigame, or as part of a team player-versus-monster event. Many quests feature boss fights at their climaxes; such bosses are often the main antagonists of the quests or quest series, or are somehow related to the main antagonist(s). Some monsters that are commonly referred to as bosses are very powerful monsters that reside in multi-combat areas; these monsters are commonly fought by teams of players in search of highly valuable drops. Many bosses have extremely high combat levels, and most of the strongest monsters in the game are bosses. With the exception of Bryophyta and Obor, bosses are exclusive to members.
