Boss

A Boss is an opponent Non-player character (NPC) or monster, often of a high level who either must be defeated to obtain a reward in a quest, (normally at the end) or minigame, or is a significant high level monster such as the King Black Dragon that may be the only monster ingame to drop certain items. Most often there is only one type of the monster and it only has to be defeated once. In most high-levelled quest bosses and non-quest bosses, using prayer is only partly effective or you cannot use prayer at all. In addition, Dwarf multicannon cannot be used against most of these bosses, because they might destroy your cannon.

Non-Members can fight the following bosses: Count Draynor, Delrith, Elvarg, Melzar the Mad, Dragith Nurn, and Gunthor the Brave.
