Boss

The RuneScape Wiki also has an article on: rsw:Boss

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

This article or section requires a cleanup in order to meet the Old School RuneScape Wiki's quality standards. Reason: Inconsistency throughout page presentation You can edit this page to improve it.

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".

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

Raids' bosses

• Chambers of Xeric is where the raids activity takes place featuring 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 raid can contain any of the five sub-bosses (Vasa Nistirio, Tekton, Vespula, Vanguard, and the Muttadile), but the final boss will always be Great Olm.

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

• Theatre of Blood is where the raids activity takes place featuring multiple bosses with many mechanics. This uses a performance system, where the better the player performs, the more likely they are to obtain a drop, such as justiciar armour and scythe of vitur. These raids always contain five sub-bosses in the following order (The Maiden of Sugadinti, Pestilent Bloat, Nylocas Vasilias, Sotetseg, Xarpus), with the final boss being Verzik Vitur.

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 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.

Boss slayer

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:

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

Minigame bosses

The fearsome and mighty TzKal-Zuk, an ancient adversary to the TzHaar.

These bosses are fought as parts of minigames.

• The six Barrows brothers can be thought of as bosses, as each is quite powerful and together they are fought during the Barrows minigame. The brothers and their combat styles and levels are Ahrim the Blighted (Magic, 98), Dharok the Wretched (Melee, 115), Guthan the Infested (Melee, 115), Karil the Tainted (Ranged, 98), Torag the Corrupted (Melee, 115) and Verac the Defiled (Melee, 115). Each is an undead spirit and wears a certain set of equipment that gives a certain set effect; this equipment, known as Barrows equipment, can be obtained from the activity, and is highly popular as the sets are among the most powerful combat equipment in the game.
• TzTok-Jad is the final boss of the TzHaar Fight Cave minigame. It is level 702 and is extremely dangerous as all of its attacks, which hit from every side of the combat triangle, can each deal up to 98 damage. Additionally, TzTok-Jad summons Yt-HurKot to rapidly heal it once it reaches half health. The reward for defeating TzTok-Jad is 8,032 Tokkul and the Fire cape.
• TzKal-Zuk is the final boss of the Inferno minigame. It is level 1400 and possesses a max hit of 251, meaning getting hit by one of its attacks is almost certain death. Its attacks can be avoided by hiding behind the shield that appears during the fight. However, Jal-Xil and Jal-Zek will appear periodically throughout the fight and attempt to destroy the shield. Additionally, it will summon a JalTok-Jad and Jal-MejJaks at different periods of the fight. The reward for defeating Tzkal-Zuk is 16,064 Tokkul and the Infernal cape.
• The Penance Queen is the level 209 boss of the Barbarian Assault minigame; she is fought during the tenth and final wave. She uses rapid Melee and Ranged attacks and can only be damaged with omega eggs fired from the egg launcher. Defeating her earns players 80 honour points in their chosen roles, and five points in the other roles.
