Boss

A boss is a powerful, usually unique monster that is fought to accomplish an objective. 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.

Each boss has its own hiscore table, tracking the players with the most kills, or raid completions in the case of raid bosses. Each of these bosses has unique drops in the collection log. Most bosses will generate a message upon kill telling the player what drop(s) they have obtained. For example, if players are at Callisto and kill him (and drops Voidwaker hilt), a message will appear in the game box saying "Player name received item: Voidwaker hilt".

List of bosses

Wilderness bosses

The following world bosses are specifically located within the Wilderness, where players may attack each other. The one exception is the King Black Dragon: his lair where the fight takes place is not located in the Wilderness, but it can only be accessed through Wilderness, and is thus still considered risky.

Warning: As these bosses are located deep within the Wilderness, and wander around in a multi-combat zone, beware of player-killers! Do not bring items you are not willing to lose.

World bosses

World bosses spawn across Gielinor either out in the open or in their lairs. World bosses are defined as bosses which spawn naturally, on their own, and can be killed at any time, as opposed to instanced bosses which spawn only in private lairs based on the actions of the player to whom the instance belongs.

Instanced bosses

As opposed to world bosses, instanced bosses can only be killed by a single player in the boss's lair, without the aid or even presence of other players.

Sporadic bosses

Sporadic bosses are those that cannot be fought whenever the player wishes. Instead, they require a special item of some sort to gain access to them, which is obtained by partaking in other more common activities. Naturally, these bosses will also be instanced given the nature of their sporadic logistic.
