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 multicombat 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.

Dwarf multicannons often cannot be set up in the areas of many bosses. Others may have different restrictions; for example, Prayer cannot be used during the fights with the final bosses of Recipe for Disaster.

General bosses (e.g bosses like the Corporeal Beast) also reside in a multi-way area; very few reside in single-way areas. Bosses that are killed in multi-way areas will also generate a message telling the player what drop(s) they have obtained, regardless if there are other players around or not. For example, if players are at General Graardor and kill him (and drops Bandos tassets), a message will appear in the game box saying "Player name received item: Bandos tassets." If a boss is killed in a single-way area, this message will not appear, even if the boss resides in a multi-way area and is killed in a single-way zone.

Boss slayerEdit

Players who have unlocked the Like a boss ability via spending 200 Slayer reward points can have Nieve (Steve after Monkey Madness II) or Duradel assign them boss monsters in addition to the tasks they already assign. The Slayer Master will randomly assign a boss if they can meet those requirements; for example, they can assign the Dagannoth Kings to the player (since there are no special requirements), but will not assign them Commander Zilyana if they do not have 70 Agility.

Once a boss has been assigned, they will ask the player to select the amount that they want to kill for their assignment. The player can select anywhere from 3-35 times to kill that boss(es). Make sure that you want to kill that much of the boss, as once you hit enter, this decision cannot be reversed.

Note that the Slayer helmet (i) does work during boss slayer tasks. To progress towards a boss task, the player must either land the final blow or deal the most damage to the boss, just as in regular Slayer. Bosses will also give Slayer experience upon death, and upon finishing a boss task, the player will get an additional 5,000 Slayer experience.

The following bosses can be assigned:

Kree'arra Commander Zilyana General Graardor
K'ril Tsutsaroth Dagannoth Kings Cerberus
Giant Mole Kalphite Queen Venenatis
King Black Dragon Callisto Chaos Fanatic
Vet'ion Chaos Elemental Barrows (Brothers only, not chests)
Crazy archaeologist Scorpia Thermonuclear smoke devil
Zulrah Kraken Abyssal Sire

Common PvM bossesEdit

The monsters included in this section are often killed by clans or otherwise organised teams of players for PvM (player vs monster) events. Each is found in a multicombat area, allowing many players to engage them simultaneously, and are often killed for valuable and/or unique items that they drop. Most are extremely powerful, and some may require specific strategies to fight effectively.

God Wars Dungeon generalsEdit

K'ril Tsutsaroth
