Old School RuneScape Wiki
This article is about the strongest class of monsters. For other uses, see Boss (disambiguation).

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. 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.

Common PvM bosses

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

Commander Zilyana, holy champion of Saradomin

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.

Wintertodt, currently the only "skilling boss" in Old School RuneScape.

Skilling bosses

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.

Other bosses

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 labeled under the Wilderness category because PvP attacks are disallowed in his cave, whereas PvP attacks could happen while fighting the other bosses labeled as "actual Wilderness Bosses", even though the Corporeal Beast's cave is indeed 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.
  • 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


The Grotesque Guardians are a boss version of Gargoyles found on the Slayer Tower's rooftop, whose entrance is found on the 2nd floor[?]. In order to access the roof, players must obtain a brittle key from gargoyles while assigned them for a Slayer task. The Grotesque Guardians require 75 Slayer and can only be killed while the player is assigned gargoyles or the Guardians themselves. The pair consists of Dusk and Dawn.

Abyssal Sire.png

The Abyssal Sire is the boss version of the Abyssal demon. It requires level 85 Slayer to kill. Located within the Abyssal Nexus (accessible via fairy ring DIP or the Abyss), it can only be attacked if you have them as a Slayer assignment. This monster drops the unsired, which can be used at the Font of Consumption giving players a chance of receiving the Abyssal dagger and the three pieces of the Abyssal bludgeon (bludgeon axon, claw and spine) as well as its boss pet, the Abyssal orphan. It shares the Abyssal whip drop with its non-boss variant.

Cave kraken.png

The Kraken is a stronger and larger version of the Cave kraken. It requires level 87 Slayer to kill. Located at the Kraken Cove, it can only be attacked if you have it (or Cave Kraken) as a Slayer assignment. Along with these monsters and their non-boss variant, they are the only monsters that drop the Kraken tentacle. Other notable drops include the Trident of the seas and a pet kraken.


Cerberus is the boss version of the Hellhound. It requires a minimum of 91 Slayer to kill. Located at Cerberus' Lair, it can only be attacked if you have them as a Slayer assignment. Notable drops include the primordial, pegasian, eternal crystals and a hellpuppy. It shares the Smouldering stone drop with its weaker cousins, although at a far better rate.

Thermonuclear smoke devil.png

The Thermonuclear smoke devil is the boss version of the Smoke devil. These require a minimum of 93 Slayer to kill. Located at the Smoke Devil Dungeon, they can only be attacked if you have them as a Slayer assignment. This monster is the only monster to drop the Smoke battlestaff. Their non-boss variants, however, also drop the Occult necklace.


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 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 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 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:

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