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.

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.

Most bosses (e.g. bosses like the Corporeal Beast) also reside in a multi-way area; very few reside in single-way areas or instances. Most bosses will also generate a message upon kill telling the player what drop(s) they have obtained. 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".

Common PvM bosses[edit | edit source]

The monsters included in this section wouldn't better fit in any other categories, and are located in some spot in the game-world that are accessible/reachable to anyone, without any restrictions. However, despite their accessibility, many players prefer to have certain diaries done before killing these with dedication, since the rewards from those Diaries can be game-changing in the long-run: those rewards could range from making it significantly easier to access the Boss to making the manner in which you earn the drops, from these bosses, significantly more convenient.

God Wars Dungeon generals[edit | edit source]

General Graardor, powerful champion of Bandos

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.

The Great Olm, the final boss in the Chambers of Xeric and the third strongest monster in the game.

Raids' bosses[edit | edit source]

Verzik Vitur, the final boss in the Theatre of Blood and strongest monster in the game.

Sporadic bosses[edit | edit source]

Sporadic bosses are those that can't be fought whenever the player wishes to, instead, they require a special item of some sort to gain access to them, which is obtained by partaking in other more common activities. The bosses in this category can also be considered demi-bosses.

Skilling bosses[edit | edit source]

  • The 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 Ironmen who can't successfully kill the Dagannoth Kings.
Wintertodt, currently the only "skilling boss" in Old School RuneScape.

Other bosses[edit | edit source]

Corporeal Beast, currently the fourth strongest monster in Old School RuneScape.
  • The Corporeal Beast was the highest-level monster in Old School RuneScape with a combat of 785. It is not labelled under the Wilderness category because players can immediately reach its lair via a Games necklace, even though its cave is located "within" the Wilderness. It can be extremely dangerous to fight as a solo player, therefore, players often team up to kill it. It is the only monster that drops Sigils for spirit shields.
  • Vorkath is a very powerful blue dragon who was first encountered during Dragon Slayer II as a penultimate boss. After completion of said quest, he becomes stronger and available for solo battle, possessing a combat level of 732. He is the only monster to drop the skeletal visage and dragonbone necklace.
  • 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 travelling routes. With a combat of 725, he is currently the sixth highest-level monster in the game. He is the only monster to drop the tanzanite fang, magic fang and serpentine visage.
  • The Deranged archaeologist, actually a demi-boss, is mostly inspired by the Wilderness "Crazy archaeologist". This one, though, is located in the Tar Swamp of Fossil Island. He can attack with both melee and ranged combat styles. His combat level is 276 but has no unique drops on his drop table. When you enter his "lair", you'll get hit with some big damage, something above 40. His special attack is a "devastating" multi-area attack that can deal a stack of multiple damage hitsplats if the player doesn't avoid it quick enough by running away.

Slayer bosses[edit | edit source]


The Grotesque Guardians are a boss version of Gargoyles and are found on the rooftop of the Slayer Tower, whose entrance is found on the 2nd floor[?]. In order to unlock the roof permanently, players must first use a brittle key on the entrance, which is obtained by killing regular gargoyles under a Slayer task. The Grotesque Guardians require 75 Slayer and can only be killed while the player is assigned the usual gargoyles or the Guardians themselves. The pair consists of Dusk and Dawn and can drop a pet version of them with an option to metamorphosis between the two.

Abyssal Sire.png

The Abyssal Sire is the boss version of regular Abyssal demons. They require level 85 Slayer to kill. Located within the Abyssal Nexus (accessible via fairy ring DIP or the Abyss), this boss can only be attacked if you have it or the regular Abyssal demons as a Slayer assignment. Its unique drop is the unsired, which can be used at the Font of Consumption, giving players a chance of receiving either a Jar of miasma, an Abyssal orphan, an Abyssal dagger, an Abyssal whip, an Abyssal head or one of the three pieces of the Abyssal bludgeon (bludgeon axon, claw and spine).

Cave kraken.png

The Kraken is a stronger and larger version of the regular Cave krakens. These require at least level 87 Slayer to kill. It is located at the Kraken Cove, and everything in said cove can only be attacked if you're under a Slayer assignment. It has chances to drop the Pet kraken. In addition, the boss Kraken and the non-boss variant are the only monsters that can drop the Kraken tentacle and the Trident of the seas.


Cerberus is the boss version of Hellhounds. It requires a minimum of 91 Slayer to kill. Located at Cerberus' Lair, it can only be attacked if the player has it or regular hounds as an assignment. Unique drops include the primordial, pegasian and eternal crystals, and of course, a hellpuppy. It shares the Smouldering stone drop with its weaker cousins, although at a far better rate than those.

Thermonuclear smoke devil.png

The Thermonuclear smoke devil is the boss version of Smoke devils. These require a minimum of 93 Slayer to kill. It is located at the Smoke Devil Dungeon, and everything in this dungeon can only be attacked if you're under a Slayer assignment. This monster is the only one to drop the Smoke battlestaff and its respective pet. The non-boss variant, however, shares the Occult necklace drop with the boss.

Alchemical Hydra (two heads).png

The Alchemical Hydra is the boss version of regular Hydras. These require a minimum of 95 Slayer to kill. The boss is located at the Karuulm Slayer Dungeon and can only be attacked if the player has it or regular hydras as a Slayer assignment. It can drop the Ikkle hydra and two more uniques: the Hydra leather and Hydra's claw, involved with the creation of Ferocious gloves and the Dragon hunter lance, respectively. This boss also shares a few more notable drops with its regular variants: the Hydra tail (used to create a Bonecrusher necklace) and the Hydra's eye, fang and heart (which would create a Brimstone ring upon combining the three together).

Boss slayer[edit | edit source]

Not to be confused with the actual Slayer bosses themselves. Players who have unlocked the Like a boss ability via spending 200 Slayer reward points can have Konar, Nieve/Steve, Duradel, or Krystilia 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 any player (since there are no special requirements), but Commander Zilyana can only be assigned if the player has 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 (a maximum of 15 if Zulrah is assigned) to kill that boss or those bosses. 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:

Minigame bosses[edit | edit source]

The Penance Queen, nemesis of the Barbarians

These bosses are fought as parts of minigames.

Quest bosses[edit | edit source]

The Culinaromancer, the evil culinary sorcerer, and main antagonist of Recipe for Disaster.

A large number of quests involve and/or conclude with a battle against a powerful monster, which often is or is related to the quest's main antagonist. Except where otherwise noted, these bosses can only be fought in the Nightmare Zone once their respective quest has been completed.

A sub-boss is a powerful or semi-powerful monster fought as a prelude to the actual boss fight.

Glod, a giant who resides at the top of the beanstalk in Grim Tales.
Vorkath, a very powerful blue dragon and penultimate boss encountered during and post-Dragon Slayer II.
Glough, an antagonist of the gnome quest series in his mutant form in Monkey Madness II.

Quests with multiple bosses[edit | edit source]

Some quests have several boss monsters that must be defeated, usually one after the other.

Nightmare Zone[edit | edit source]

Main article: Nightmare Zone

The Nightmare Zone is a minigame that allows players to fight bosses from quests they have completed. Players can fight up to 42 unique boss monsters from previous quests.
