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. With the exception of Bryophyta and Obor, bosses are exclusive to members.
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".

Sporadic bosses[edit | edit source]
Sporadic bosses are those that cannot 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. Obor and Bryophyta are among the few free-to-play bosses.
|Name||Image||Level||Hitpoints||Attack style||Location||Requirement||Unique drops|
|Obor||106||120||Melee, Ranged||Western wall of the Hill Giant area, by the southern part of the Edgeville Dungeon||Giant key||Hill giant club|

Skilling bosses[edit | edit source]
Skilling bosses are not fought traditionally with combat, but rather by utilising non-combat skills to defeat them.

Raids[edit | edit source]
Raids are high-level activities with a set of bosses that players can fight either alone or with a team.
Chambers of Xeric[edit | edit source]
Bosses within the Chambers of Xeric are sporadic: as the layout of each raid is randomised, the bosses that players will encounter as well as their order may vary, with the exception of the Great Olm, which appears at the end of every raid. This is not the case if the Challenge Mode is enabled, where each boss is encountered and there is no randomisation. Each boss' stats also scale to the amount of players in the raid and their combat level. All bosses except ice demon and the Great Olm drop potions, seeds or ingredients to use in the raid; once the Great Olm is defeated, the exit is opened and players can collect their loot, the quality of which scales to their performance in the raid.
|Name||Image||Standard attack style||Special attacks or mechanics|
|Tekton||Melee||Regenerates health periodically and targets players with damaging sparks|
|Ice demon||Ranged, Magic||Must be thawed by lighting the braziers, attacks based on players' protection prayers|
|Lizardman shaman||Ranged||Summons spawns that explode; uses a moderately damaging acid attack; jumps on the player; all three special attacks can be dodged|
|Vanguard||Melee, Magic, Ranged||All three vanguards reset health if they are not within less than 33% of each other's health (or 40% if the raid has less than five people)|
|Vespula||Melee, Ranged||Spawns vespine soldiers; cannot be killed directly (the abyssal portal must instead be destroyed)|
|Guardian||Melee||Causes a boulder to drop from the ceiling|
|Vasa Nistirio||Ranged||Regenerates health periodically through glowing crystals; stuns players before casting a high damage attack|
|Skeletal Mystic||Magic, Melee||None|
|Muttadile||Melee, Ranged, Magic||Regenerates health from the meat tree unless it is cut down|
|Great Olm||Magic, Ranged||Has a multitude of special attacks|
Theatre of Blood[edit | edit source]
Unlike the Chambers of Xeric, bosses within the Theatre of Blood take place in a predetermined order. Their hitpoints are scaled depending on the number of players from three to five; if there are only one or two players, the scaling for three players is used, and five is the maximum number of players per team. Bosses do not drop anything, although there are resource chests where players can obtain potions and food for upcoming encounters; after defeating Verzik Vitur, the entrance to her vault is opened where players can obtain their loot, the quality of which scales to their performance in the raid.
|Name||Image||Standard attack style||Special attacks or mechanics|
|The Maiden of Sugadinti||Magic||Spawns Nylocas Matomenos and blood spawns; creates blood splats that damage players and heal her|
|Pestilent Bloat||Ranged||Spawns flies that deal rapid damage within line of sight; stomp attack that deals high damage within line of sight|
|Nylocas Vasilias||Magic, Melee, Ranged||Multiple waves of smaller nylocas must be defeated before the boss encounter; heals with and reflects damage done with the incorrect style|
|Sotetseg||Melee, Magic, Ranged||Launches a ball of energy where its high damage must be dispersed between players; teleports a player into the Shadow Realm with a maze for other players to follow|
|Xarpus||N/A||Heals from exhumes not blocked by players; spits acid on players' locations; can reflect damage|
|Verzik Vitur||Magic, Ranged, Melee||Has a multitude of special attacks across three phases|
Minigame bosses[edit | edit source]
These bosses are fought as parts of minigames.
|Name||Image||Level||Hitpoints||Attack style||Associated minigame|
|Penance Queen||209||250||Melee, Ranged||Barbarian Assault|
|Crystalline Hunllef||674||600||Magic, Ranged||The Gauntlet|
|TzTok-Jad||702||250||Magic, Melee, Ranged||TzHaar Fight Caves|

Boss slayer[edit | edit source]
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, or 36 if Barrows is assigned) to kill that boss. Upon finishing a boss task, the player will get an additional 5,000 Slayer experience.
The following bosses can be assigned:
- Abyssal Sire
- Alchemical Hydra
- Barrows (Brothers only, not chests)
- Chaos Elemental
- Chaos Fanatic
- Commander Zilyana
- Crazy archaeologist
- Dagannoth Kings
- General Graardor
- Giant Mole
- Grotesque Guardians
- K'ril Tsutsaroth
- Kalphite Queen
- King Black Dragon
- Thermonuclear smoke devil
