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.
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.
- The Giant Mole is, true to its name, an enormous mole, level 230, that lives in its lair under Falador Park. A light source is required to fight it. During combat, the Giant Mole attacks with Melee and burrows around its rather large lair. Its chief drops, mole skin and mole claws, may be given to Wyson the gardener in exchange for bird's nests.
- The King Black Dragon is an enormous, level 276, three-headed black dragon that resides in his own lair beneath the Lava Maze. He has the ability to drain stats, freeze players, and poison with different forms of his dragonbreath, all of which are unique among dragons to the King Black Dragon. The KBD has a unique drop, his own heads, which can be mounted in a player-owned house or traded along with 1,000 Slayer points in order to colour a Slayer helmet black. He also drops valuable items, such as the draconic visage and the dragon pickaxe.
- Three level 303 Dagannoth Kings lair deep under Waterbirth Island. Each uses a different combat style: Dagannoth Supreme attacks with Ranged, Dagannoth Rex attacks with Melee, and Dagannoth Prime attacks with Magic. Altogether, the Kings drop several unique items, such as Seercull, dragon hatchets, berserker rings and mud battlestaves. They also drop a variety of Fremennik-related arms and armour, such as archer helms and skeletal armour.
- The Chaos Elemental is a level 305 creature of pure chaos that resides in deep Wilderness, near the Rogue's Castle. In addition to attacking with all three combat styles, it can teleport players around it and unequip their items. It drops the dragon two-handed sword and the Chaos Elemental pet.
- The Kalphite Queen is the ruler of the kalphites; she can be found at the bottom of the Kalphite Lair in the Kharidian Desert. Unlike many other bosses, she has two forms, both of which are level 333, and she uses protection prayers to block different attack styles. Her attacks are extremely accurate and very deadly for players who are unprepared for them. She drops the dragon chainbody and dragon two-handed sword; she also drops her head, which can be mounted in a player-owned house.
God Wars Dungeon generalsEdit
For each warring deity in the God Wars Dungeon, there is a very powerful leader commonly referred to as a 'general'. Each general also has three bodyguards, one of which uses each style of combat: Melee, Magic and Ranged. In addition to the 60 Strength or 60 Agility required to enter the God Wars Dungeon, each general's encampment has further requirements to enter.
- Commander Zilyana is the level 596 Icyene general of Saradomin, attacking rapidly and accurately with both Melee and Magic. Her bodyguards are Starlight, Growler and Bree. She drops the Saradomin hilt, and she and her bodyguards drop the Saradomin sword and Armadyl crossbow. 70 Agility is required to enter the Saradomin Encampment. Two ropes are needed to access her chamber if entering her encampment for the first time.
- K'ril Tsutsaroth is the level 650 demonic general of Zamorak. He is extremely poisonous and can hit through protection prayers with his powerful Melee and Magic attacks. His bodyguards are the demons Tstanon Karlak, Zakl'n Gritch and Balfrug Kreeyath. He drops the Zamorak hilt, and he and his bodyguards also drop the Zamorakian spear and Staff of the dead. Entering the Zamorakian encampment requires 70 Hitpoints, which implies but does not strictly require 70 Hitpoints (boosts such as Saradomin brews can be used).
- General Graardor is one of the last known living ourgs, although he may very well be the only ourg in existence. He is the level 624 general of Bandos and is the most popular God Wars Dungeon general to kill, despite his devastating Melee and Ranged attacks. His bodyguards are Sergeant Strongstack, Sergeant Grimspike and Sergeant Steelwill. Along with the Bandos hilt, General Graardor and his bodyguards drop pieces of Bandos armour. 70 Strength and a hammer (Dragon warhammer also works) are required to enter the Bandos encampment.
- Kree'arra the Aviansie is the level 580 general of Armadyl. Being a guardian and leader of the Aviantese, he cannot be attacked with Melee weapons, though he uses all three styles himself. His bodyguards are Flight Kilisa, Flockleader Geerin and Wingman Skree. Kree'arra himself drops the highly valuable Armadyl hilt, and he and his bodyguards drops pieces of Armadyl armour. Entering Armadyl's encampment requires 70 Ranged and a mithril grapple.
- The Corporeal Beast was the highest level monster in Old School RuneScape with a combat of 785. Although it is extremely dangerous to fight, players often team up as it is the only monster that drops sigils for spirit shields.
- Zulrah is a powerful, solo-only boss, where one cannot attack with Melee and must use Ranged or Magic. Partial completion of Regicide is required to access this boss; however, completing the quest is recommended to unlock faster traveling routes. With a combat of 725, he is currently the third highest-level monster in the game. He is the only monster to drop the Tanzanite fang, Magic fang and Serpentine visage.
- Wintertodt is the only skilling boss in Old School RuneScape. Players must light the braziers and burn logs or make them into kindling, using the roots found near the braziers. This is the only place where the tome of fire can be awarded and has a very rare chance of receiving a dragon axe, an alternate for Ironman skillers who cannot kill the Dagannoth Kings.
- Chambers of Xeric is where the raids activity takes place features multiple bosses with many mechanics. This uses a score system which improves the chance of receiving unique loot, such as dragon claws and twisted bow.
A demi-boss is a monster possessing boss-like abilities but is slightly weaker than a traditional boss. Although lizardman shamans and demonic gorillas are conventional monsters, they also fit the demi-boss category and are thus considered demi-bosses.
