OSRS Boss overview and ultimate Tier List [2022]

The best thing about OSRS is bossing. Fighting a new boss and getting some great loot out of it is by far the thing we like to do the most on this Medieval clicking generator. While our RNG is never quite what we want it to be, it is almost always fun to solo, duo a boss, or go on a PVM trip with your clan. 

Killing bosses on OSRS isn’t just a ton of fun, and it is also one of the best consistent money-makers. This overview discusses the most interesting bosses RuneScape has to offer and rank them on a tier list.

OSRS Bosses tier list ranked

Unfortunately, Tiermaker does not have all the bosses, so we have made this amazingly designed Tier List table. 

Our Old School Runescape Boss Tier List criteria 

We use two different criteria for our OSRS Boss Tier list. These are fun and drops. We do consider the requirements, the difficulty, and if you can solo, duo, or fight them in a group. 

  • Fun: Playing OSRS in your late 20’s needs to be fun. The reason why the game is holding up so well is the fact that you can AFK a ton to get the skills you need. However, getting high-level stats still takes a ton of time. The time investment to get the requirements to fight the boss needs to be worth it in the end. We don’t want to see a one-dimensional boss with boring mechanics or one where the fight is just an endless drag. We just want to have fun doing bossing. 
  • Drops: Another essential requirement for our Tier list is what the bosses drop. While the giant mole, in our opinion at least, is a pretty fun boss to fight, the drops are so bad we don’t want to fight it ever again after getting the pet. While we don’t want every boss to be at least 10m gp/h, having yew logs as the most valuable drop won’t score a ton of points and won’t get the boss an S tier. 

What types of OSRS Bosses are there? 

Regular bosses

A ‘regular’ boss is one for which you do not need some special requirements. These are, for example, the God Wars Dungeon bosses, the KBD, and the Giant mole. While you sometimes need to have high agility or a decent enough combat level to kill them, they are not locked behind a slayer task and don’t (generally) appear in an instance. 

Slayer bosses 

Slayer bosses in OSRS are boss monsters that you can only fight and kill when you have 1) the appropriate slayer level and 2) you have a slayer task related to that boss. Generally speaking, the Slayer boss is a much more potent variant of the regular slayer monster. While they are much harder to kill, they give more exp and have far superior loot. Often they also have unique drops that only they drop. 

Mini-game Skilling bosses

Skilling bosses are a special kind of boss. You can only kill these by using skills. The best-known example of this is Wintertod. This boss, you need to defeat with your firemaking skill. There is also a fishing boss named Temporos. Both are pretty unique and can be fought at level 3 combat. 

There are also mini-game bosses. The most well-known of these are the barrows brothers. Yes, barrows is technically a mini-game in OSRS and RS3.

Quest bosses

A Quest boss is a monster you have to fight and kill during a quest. A famous example of a powerful quest boss is the Sins of the Father boss, Vanstrom Klause, Count Draynor (yes, he is a boss) from Vampire Slayer and Elvarg the Dragon Slayer are also very well-known examples of these monsters. Many quest bosses can be fought again in the Nightmare Zone in Yanille. However, they do not have (decent) drops. Quest bosses are as good as always solo fights. There are also bosses to unlock after quests like Vorkath and the Rabbit boss.

Instanced Bosses

Instanced bosses are bosses that are generated in an instance. These are areas only you can access. An excellent example of an instanced boss is Skotizo. You can only access him after using a totem in the Kourend Catacombs. Another instanced boss, is the Mimic. This boss is also named a sporadic boss.

As a matter of fact, all 2 F2P bosses are instanced. The significant advantage of an instanced boss is that you have the area to yourself and can’t get crashed by a team or a player with better gear. 

Obor

Obor is the hill giant boss and the first real F2P boss you can fight multiple times. However, he can only be accessed by killing regular hill giants and getting a giant key drop. When you have gotten this key, you can access the boss through a special door in the Edgeville Dungeon. 

While the boss is very easy in members, it can be slightly hard in F2P at the medium levels since your gear is much weaker. Therefore, I would strongly advise you to wait until at least level 70 combat and 40 prayer till you fight him in F2P.

  • Location: Southern part Edgevill Dungeon
  • Combat level: 106
  • Requirement: Giant Key
  • Best drops: Hill giant club and various rune items
  • Tier: Ctier

Bryophyta

The other boss that is available to members next to Obor is Bryophyta. She is the Moss Giantess and can be accessed after getting a Mossy key drop. You can get this drop from Moss Giants. The Bryophyta’s essence is worth more than 5m and thus a great way to get a bond. This monster is a bit stronger than Obor at 128 combat, making Bryophyta the strongest F2P boss in OSRS

  • Location: Varrock 
  • Combat level: 128
  • Requirement: Have a mossy key
  • Best drops: Bryophyta’s essence and various rune drops. 
  • GP an hour: 1m
  • Tier: B tier

Skotizo

Skotizo is a boss that is found in the Kourend Catacombs. Much like Obor and Bryophyta, you need an item to access it. This time you require a totem. You can get this by killing monsters in the catacombs of Kourend; however, you will need three different pieces to make one. Skotizo is known for its consistent good drops, the guaranteed hard clue scroll, and sometimes an elite clue. 

  • Location: Center of the Catacomb of Kourend
  • Combat level: 321
  • Requirement: A Dark totem
  • Best drops: Jar of darkness, Dark Claw, hard clue. 
  • GP an hour: up to 5m if you have the totems
  • Tier: A tier

Barrows Brothers

One of the oldest bosses is OSRS are the Barrows Brothers. These had completely changed the meta when they came out, thanks to the chance of getting barrows armor from the chest they guard. They also consistently drop death, chaos, and blood runes and have quite a large chance of giving you an elite clue. 

  • Location: Barrows grave hills
  • Combat level: up to 115
  • Requirement: None
  • Best drops: Barrows armor
  • GP an hour: 1m
  • Tier: C tier

Callisto

Callisto is one of the wilderness bosses in OSRS. That means that while you are fighting this monster, you can be attacked by other players. Since Callisto is in a multi combat zone, you can fight him in a group. However, that also means that multiple Pkers can attack you. One of the best ways to fight Callisto is in full Verrac since it can negate Callisto his massive defense bonuses. Ironman fight this monster to get the Dragon Pickaxe drop. Callisto attacks with both melee and magic. 

  • Location: Wilderness, South of Demonic ruins
  • Combat level: 470
  • Requirement: None
  • Best drops: Tyrannical Ring and Dragon Pickaxe. 
  • GP an hour: 2.5m
  • Tier: B tier
OSRS boss tier list callisto

Vet’ion

Another popular wilderness boss is Vet’ion. Unlike Venenatis and Callisto, Vet’ion has two different stages and can summon two skeleton hellhounds to assist him in the fight. He can attack with both melee and magic and is pretty strong. However, his defense bonuses are a lot lower than these of Callisto. Because Vet’ion is in a multi combat zone, you fight him in a group, but multiple Pkers can also attack you. 

Vet’ion drops the best prayer ring in the game and also drops the dragon pickaxe. 

  • Location: Wilderness North of the Boneyard
  • Combat level: 454
  • Requirement: None
  • Best drops: Ring of the Gods and Dragon pickaxe. 
  • GP an hour:
  • Tier:

Kraken

The Kraken is a Slayer monster that requires level 87 slayer to fight, and you need to be on Kraken slayer task. They are a very easy monster to fight and can even be AFK’ed for a bit if you have high enough stats or use blood burst, blitz, or barrage. Players often skip them because their GP an hour is quite slow, and they take quite long to kill. You can pay 25k to have an instanced area all to yourself. 

  • Location: Kraken Cove
  • Combat level: 291
  • Requirement: 87 slayer and a slayer task
  • Best drops: Kraken tentacle, the trident of the seas, and Kraken pet
  • GP an hour:
  • Tier:

Abyssal Sire

I absolutely hate this boss, but the Abyssal sire does have some decent drops. Our co-writer Huang absolutely loves the mechanics for some reason, but I imagine this is one of the least popular bosses to kill on OSRS.

The Abyssal sire is a slayer boss and a stronger variant of the abyssal demon. It is a pretty strong monster, but like most slayer bosses, you can grind out multiple in a trip—the abyssal sire attacks with melee. 

  • Location: Abyssal Nexus
  • Combat level: 350
  • Requirement: 85 slayer and a slayer task
  • Best drops: Abyssal Pet, Unsired, which can be used to get an abyssal bludgeon
  • GP an hour:
  • Tier:

Chaos Elemental 

The chaos elemental is one of the oldest OSRS bosses. You can find him/her/it in deep wildy, so do not bring items you are not willing to lose. While the drops are nothing special, they have a pretty high chance of dropping pet chaos elemental. Killing this monster is one of the fastest ways to get yourself. The Chaos Elemental attacks with magic, range, and melee and is the only monster in OSRS that drops the dragon 2H. 

  • Location: West of the Rogues Castle
  • Combat level: 305
  • Requirement: None
  • Best drops: Dragon pickaxe and Chaos elemental pet
  • GP an hour:
  • Tier:

Alchemical Hydra

By far, one of the best monsters to get as a slayer task are (alchemical) Hydras. Unfortunately, these monsters are locked behind a massive requirement of 95 slayer. However, the rewards are well worth it, and the Alchemical Hydra is a ton of fun to fight. The Hydra has four different stages and can two hit you quite easily if you do not pay attention. The rotations are quite easy to learn, and you can fight a whole ton of them in a single trip.

The only downside is that a single task tends to take multiple days. Of course, you can fight the regular Hydra’s too, but we think it is a waste of your slayer task as it is some of the best money in the game

  • Location: Karuulm Slayer Dungeon
  • Combat level: 426
  • Requirement: 95 slayer and a slayer task
  • Best drops: Hydra leather, Hydra’s claw, Hydra pet
  • GP an hour:
  • Tier: S

Cerberus

Cerberus is the one slayer boss that every ironman is striving though kill. Cerberus has a ton of useful drops and is a very good exp both in combat and slayer. Therefore, you do need to have a task to kill him. However, since hellhounds are often assigned, and he counts as one, this generally isn’t a problem. 

Cerberus has a ton of mechanics that can make him quite a hard boss to kill if you aren’t used to bossing. However, if you have decent enough gear, you can easily defeat him ten times a trip or more. High agility is recommended since he is far away from a teleport unless you have the specific one. Cerberus attacks with melee ranged and magic. 

  • Location: Cerberus Lair
  • Combat level: 318
  • Requirement: 91 slayer and slayer task
  • Best drops: Primordial crystal, Pegasian crystal, eternal crystal, and Hellpuppy. 
  • GP an hour:
  • Tier:

Grotesque guardians

The grotesque guardians are not one but two monsters, Dusk and Dawn. The two work as a team to defeat you, but they aren’t very strong. They are the first slayer exclusive boss you will come across. They only require a slayer level of 75 and are a (much) stronger version of gargoyles. 

Dusk and Dawn attack with all three combat styles; melee, ranged, and magic. Generally speaking, they aren’t worth killing. They have abysmal drops and take quite a while to defeat. However, the Grotesque Guardians are excellent to learn how to boss in OSRS. 

  • Location: Slayer tower, top floor
  • Combat level: Dusk is combat 248, and Dawn is combat 228
  • Requirement: 75 slayer, access to the roof, and slayer task
  • Best drops: Granite gloves, Granite ring, Granite hammer, Black tourmaline core
  • GP an hour:
  • Tier:

Giant Mole 

The Giant Mole is one of the easiest bosses in OSRS. You can find her under Falador Park. Giant Mole is best fought after doing the Falador Hard Diaries since it has a very annoying mechanic where it can run away after you hit it. The Falador Shield will give you a very handy arrow indicator on your map to show you where exactly the Giant Mole reappears after it ran away. The Giant Mole uses a melee attack. 

  • Location: Under Falador Park
  • Combat level: 230
  • Requirement: Use a Spade to dig 
  • Best drops: Mole skin, Mole claw, pet mole 
  • GP an hour:
  • Tier: 

King Black Dragon

The King Black Dragon or the KBD is one of my favorite bosses to fight as soon as my combat is high enough. While extremely iconic and very nostalgic, the KBD is easy to defeat and has mediocre drops. You also need to travel a bit through the wilderness, so make sure you are not bringing anything you are unwilling to lose.

The King Black Dragon is a great monster to work towards when you are a new account or if you want to go bossing with a friend. Due to the fun of fighting, the KBD gets a pretty high tier, but the drops really aren’t anything special, and the good ones are very rare. 

  • Location: His lair in the deep wilderness
  • Combat level: 276
  • Requirement: None
  • Best drops: Dragon pickaxe, Pet, and KBD head. 
  • GP an hour:
  • Tier:

Dagannoth Rex

At OSRS Boss, we are kind of based when it comes to the Dagannoth Kings. They are just one of the best monsters to fight for medium-high level players and are great money for the low requirements. 

The melee fighter of the dagannoth kings, Dagannoth Rex, is the easiest to fight. Since you can safespot him pretty easily, you can get over 30 kills a trip, even on lower levels. Unfortunately, Dagannoth Rex drops one of the most wanted items in the entire game, the Berserker ring. 

  • Location: Waterbirth Island Dungeon
  • Combat level: 303
  • Requirement: Another player or pet rock and a rune thrownaxe
  • Best drops: Berserkers ring and Pet
  • GP an hour:
  • Tier:
dagannoth rex osrs boss

Dagannoth Supreme

The dagannoth supreme is much harder to fight due to the location in the cave. Ou will be attacked by the Dagannoth supreme (which uses range) and the Dagannoth prime (which uses magic). It is best to go in a group or have almost maxed combat if you want to fight this dagannoth king. The dagannoth supreme drops the archer’s ring, which is worth a lot of money. 

The best way to kill the dagannoth supreme is by tribiriding at a high combat level. However, it is also a fun boss to do in a group. 

  • Location: Waterbirth Island Dungeon
  • Combat level: 303
  • Requirement: Another player or pet rock and a rune thrownaxe
  • Best drops: Archers ring and Pet
  • GP an hour:
  • Tier:

Dagannoth Prime

The dagannoth prime is the magic-user of the three. When in doubt, pray magic, as the dagannoth prime hits 60s and is very accurate. Unfortunately, despite hitting so much, their drops are pretty bad. Despite being buffed to give a +6 bonus, the seer’s ring is worth well under a mil. The Dagannoth prime is the OSRS Boss who is weakest to range.

  • Location: Waterbirth Island Dungeon
  • Combat level: 303
  • Requirement: Another player or pet rock and a rune thrownaxe
  • Best drops: Seers ring and Pet
  • GP an hour: 700k
  • Tier: A

Sarachnis

Sarachnis is a pretty recent addition to OSRS and is a massive spider monster. You can find this mid-level boss in the Forthos Dungeon. Sarachnis is pretty fun to fight with two or more in a team if you are under level 100 combat. 

For higher-level players, Sarachnis is great to get elite clue scrolls. They drop them at a one in 60 rates. They are, according to many, the fastest way to get these clue scrolls. They also have a pet named Srarachna. 

The boss’s mechanics are very easy to learn, and thanks to the grubby key, you can prolong your trips. This is one of the ideal monsters to learn how to boss.

  • Location: Forthos Dungeon
  • Combat level: 318
  • Requirement: No requirement
  • Best drops: Sarachnis cudgel, Giant egg sac, Pet, elite, and hard clue scrolls. 
  • GP an hour: 1.2m
  • Tier: B

Kalphite Queen

One of the oldest OSRS monsters that used to be almost unkillable back in the day is the Kalphite Queen. The Kalphite Queen in OSRS is pretty easy to take down, even if you fight it solo. The Kalphite Queen has two phases and can use overhead prayers. The boss attacks with all three combat styles; Melee, ranged, and magic. 

Unfortunately, the drops are nostalgic, even after the multiple buffs to the drop table. The only reason why players still fight the Kalphite queen is for the elite diaries, the KQ heads, or the pet. 

  • Location: Kalphite Lair
  • Combat level: 255 (both phases) 
  • Requirement: two ropes or done the hard desert diary 
  • Best drops: Dragon chainbody, pet, KQ heads
  • GP an hour:
  • Tier:

Zulrah

Zulrah changed the OSRS meta and probably saved the economy of a specific south-American country. Even now, after the multiple nerfs to the drop table, Zulrah is still a very well-loved moneymaker in OSRS.  

Zulrah has a pretty high learning curve. So if you have never done an OSRS boss fight, you will have a pretty rough time here and probably get smacked back to Lumbridge quite a few times. Zulrah has different phases, hits high, and attacks with melee, ranged, and magic. 

Despite having such a generous drop table and being one of the best moneymakers in the game, the requirements to go and try and fight are pretty low. 

  • Location: Zul-Andra
  • Combat level: 725
  • Requirement: Completion of Regicide Quest
  • Best drops: Tanzanite fang, Magic fang, Serpentine visage, and pet. 
  • GP an hour:
  • Tier:

K’ril Tsutsaroth

K’ril Tsusaroth or the Zammy boss is one of the five bosses you can find in the God Wars Dungeon. The Zamorakian general is a greater demon, so that you can fight him during a demon slayer task. Moreover, you can also use an Arclight to boost your damage since it is a demon.

K’ril Tsutsaroth is considered to be one of the stronger bosses in GWD due to his mechanics. However, it is pretty hard to kill a ton per trip. So it is strongly advised that you duo this OSRS boss. 

  • Location: Godwars Dungeon
  • Combat level: 650
  • Requirement: 70 attack
  • Best drops: Zamorakian spear, staff of the dead, Zamorakian hilt, pet
  • GP an hour:
  • Tier:

General Graardor

General Graardor – also named Bandos – is one of the easiest GWD bosses. He is pretty easy to defeat in a group if you have a tank that knows what he is doing. At the higher levels, it is possible to solo Bandos. Graardor is easy to reach since getting 40 KC doesn’t take long, and 70 strength isn’t a high requirement to get. 

Don’t forget to take your hammer if you want to enter his room. Alternatively, you can also take a Dragon Warhammer with you like a hammer. 

  • Location: God Wars Dungeon
  • Combat level: 624
  • Requirement: 70 strength
  • Best drops: Bandos Chestplate, Bandos Tassets, Bandos boots, Bandos hilt and a pet. 
  • GP an hour:
  • Tier:

Commander Zilyana

Another God Wars Dungeon boss that is very popular and is easy to do solo is commander Zilyana. Unfortunately, the Saradomin boss requires you to have 70 agility and two ropes the first time you go to her room. The 70 agility, in particular, is a pretty high requirement for some, making this boss one of the least killed in GWD. 

If you get the hang of soloing her and have optimal gear like a twisted bow, getting up to 30 kills per trip solo is possible. In addition, she has some good drops making her well worth grinding out as an ironman. 

  • Location: God Wars Dungeon
  • Combat level: 596
  • Requirement: 70 agility and two ropes
  • Best drops: Saradomin sword, Saradomin hilt, Armadyl crossbow, a pet. 
  • GP an hour:
  • Tier:

Vorkath

Vorkath is the boss you can fight after completing the Dragon Slayer II quest. He is one of the most famous bosses to grind for money in OSRS. He is straightforward to kill once you know his mechanics. Vorkath is also the easiest OSRS boss to fight on mobile. 

The downside about Vorkath is that he is locked behind a lot of quests and gets quite dull after a while due to being pretty tedious and monotone. However, keep in mind that he is very high combat, so he one-shots you pretty quickly—Vorkath attacks with Melee (when you are in range), Magic, Ranged, and Dragonfire. 

Generally, Vorkath his drops are better than Zulrah. Unfortunately, due to him being such a famous boss to grind in Runescape, his unique drops have tanked in value quite a bit. 

  • Location: Ungael
  • Combat level: 732
  • Requirement: Complete Dragon Slayer II
  • Best drops: Skeletal visage, Vorkath’s head, and pet. 
  • GP an hour:
  • Tier:

Corporeal Beast

The Corporeal beast was the strongest monster in Runescape for quite a long time. While today, it no longer is an extreme menace thanks to the strategies and gear we have nowadays in OSRS, the corporeal beast still poses a challenge for many. 

The Corporeal beast has some of the most valuable drops in OSRS. He can easily be accessed with the game’s necklace and even has an instanced area where you can pay gold to get the boss all for yourself. 

The Corporeal Beast can one hit you, so do not underestimate him when fighting it. The boss does not use ranging but uses Melee and Magic to fight. 

  • Location: The Corporeal Beast’s lair
  • Combat level: 785
  • Requirement: None
  • Best drops: Arcane Sigil, Elysian Sigil, Spectral sigil, pet. 
  • GP an hour:
  • Tier:

The Nightmare

The Nightmare is one of the most recent OSRS exclusive bosses. The Nightmare has a couple of unique mechanics. First, you can solo the boss despite the combat level of 814. The Nightmare has some of the best drops in the game at the moment and has the best GP an hour you can get together with Theater of Blood and Nex

The Nightmare is a fun boss with poor common drops but precious, unique, rare drops. In our opinion, that is how bosses should be. Not a constant money stream but big one-time payoffs.

  • Location: Sisterhood Sanctuary (Slepe)
  • Combat level: 814
  • Requirement: Complete Priest in Peril
  • Best drops: Inquisitor’s great helm, plateskirt, hauberk, mace, nightmare staff, Eldritch orb, Harmonised orb, Volatile orb, and pet. 
  • GP an hour:
  • Tier:

Nex 

Nex is the latest new boss in OSRS and the 5th and final boss of the God Wars Dungeon. She is a follower of the ancient god Zaros. Nex is a great boss to fight in a group and is very hard to solo. 

Nex has four powerful bodyguards (Fumus, Umbra, Cruor, and Glacies), and Nex has effective attacks that can give even max combat players a tough time if they are not wearing good gear or forgetting to use the correct prayer. Unfortunately, Nex also drops the best melee gear in the game, Torva. 

Nex is a lot of fun, gives us a ton of nostalgia, and has impressive drops that make killing her well worth your time. As a result, we grant this OSRS Boss a well-deserved S-tier rating! 

  • Location: God Wars Dungeon
  • Combat level: 1001
  • Requirement: Do the frozen door mini-quest and have defeated Dad. 
  • Best drops: Zaryte Vambraces, Nihil Horn, Torva full helm, Torva Platebody, Torva platelegs, Godsword hilt, and a pet.
  • GP an hour:
  • Tier: S

OSRS Demi-bosses

Demi bosses aren’t real bosses. They are more potent than regular monsters but too weak to be considered an absolute boss. The list of OSRS Demi bosses is kind of subjective, but most people agree that these are the demi bosses. 

Chaos fanatic

The Chaos Fanatic is known because it, for some reason, also drops the Chaos Elemental pet. He is a lot closer to the wilderness edge, so he is considered a lot easier to grind for the pet. 

Chaos Fanatic attacks with both melee and magic and easily avoids a special attack that deals with severe damage. But, like most demi bosses, the chaos fanatic does not drop anything worthwhile, except for his unique drops. We place the Chaos Fanatic in the E tier for that reason. 

  • Location: West of the Lava Maze
  • Combat level: 202
  • Requirement: None
  • Best drops: Malediction shard 1, Odium Shard 1, chaos elemental pet.
  • GP an hour:
  • Tier: E

Crazy Archaeologist

The Crazy Archaeologist can be found in the wilderness ruins around level 16 wild. He is straightforward to defeat with ranging. However, if you have 40 prayer to protect melee, the Crazy Archaeologist walks in the park. 

Just like the Chaos Fanatic, the Crazy Archeologist has a pretty strong – but quickly avoidable – special attack. Unfortunately, he does not have any good drops besides the unique ones. So we will put the Crazy Archaeologist in the E tier too. 

  • Location: Ruins south of the Forgotten cemetery
  • Combat level: 204
  • Requirement: None
  • Best drops: Malediction shard 2, Odium shard 2. 
  • GP an hour:
  • Tier:

Scorpia

Scorpia is another wilderness demi boss and the final piece of the puzzle if you want to collect all Malediction and Odium shards. You can find Scorpia in the deep wild in a cavern beneath the Scorpion Pit. 

The scorpion pit is multi combat and in level 50 wild. The odds are very high. You can be PKed here. While the drops are worth more than the Crazy Archaeologist and Chaos fanatics, Scorpia is much harder to grind and just not very fun. Being attacked by a clan and being killed quickly is also a significant drawback. Scorpia is an F tier OSRS boss for us. 

  • Location: Cavern beneath the Scorpion pit
  • Combat level: 225
  • Requirement: None
  • Best drops: Malediction Shard 3, Odium shard three, and a pet. 
  • GP an hour:
  • Tier: F

Chambers of Xeric

The Chambers of Xeric, also called CoX, is different from regular bosses. CoX is a raid. Meaning you need to fight multiple bosses in order to get a reward. CoX is one of the best ways to make money in OSRS and can be done in huge groups of people (up to 100) \ but also in a small group and even solo. 

You do not get all the bosses in one raid, and they appear in random order. The exception is the final boss, Great Olm, and you will always have this boss as your final boss. 

Ice Demon

The ice demon is one of the easiest to defeat bosses in CoX. You need to keep fire burning and attack it with fire-based spells. Killing the Ice Demons takes just a few minutes. He does not drop any loot besides in-raid items. 

Muttadiles

The muttadiles are two bosses encountered in the Chambers of Xeric. They look like massive crocodiles and come in a pair of two. They are pretty intense if you do not know what to do. The best way to fight them is to use range and/or magic and get them stuck with an ice barrage. 

Lizardman Shamans

Lizardman Shamans in Cox are just like the ones you can fight outside. That means they do significant poison damage if you are not wearing the appropriate gear when you get hit by their attacks. They also have the same jump attacks as the regular Lizardman Shamans. Unfortunately, the Lizardman Shamans in the Chamber of Xeric do not drop the Dragon Warhammer or any other drop from their regular loot table. 

Tekton

Tekton is one of the most challenging bosses to fight in CoX. You need to learn the specific mechanics of the boss to make sure you can damage it. He hits high and complex and should not be underestimated, even at max combat.

Unlike the other bosses on this list, Tekton does have a valuable drop. But, unfortunately, he has a very slim chance to drop an uncut onyx. 

Vasa Nistirio

Vasa Nistro is another boss that has some fascinating mechanics. However, the boss is straightforward to defeat if you know what to do and bring a good stabbing weapon like a Zamorakian Hasta. Vasa Nistrio can be defeated in under 5 minutes, but he does not have any valuable loot like Tekton. 

Vespula

Vespula is a giant wasp boss in the Chambers of Xeric. Vespula also has quite a few interesting mechanics. However, she and her portals are straightforward to take down by using range- particularly a twisted bow. Therefore, most players do need some practice to kill this boss effectively. 

Vanguards

The vanguard trio is more like a puzzle than an absolute boss. They do not hit high, but you need to defeat all three of them simultaneously. This can be quite a hassle if you are in a team that does not know what they are doing. However, vanguards are one of the easiest bosses to fight in the Chamber of Xeric once you get the hang of it. 

Skeletal Mystics

Skeletal Mystics are another easy boss that is more demi-bosses than actual bosses. They are best fought with ranging and are very quick. You do not need to learn intricate mechanics, and you can finish the Skeletal Mystics off in a couple of minutes at most. 

Great Olm (the final boss)

Great Olm is the most demanding boss in the Chambers of Xeric. He hits high, has multiple forms, and has a ton of hitpoints. That being said, he is one of your favorite OSRS bosses. He is an exclusive OSRS monster that you can not find on Runescape 3. 

Fighting the great Olm will not be easy for your first few tries, but fortunately, you can keep trying until you manage to defeat him. Of course, you will lose points if you keep dying, but that is to be expected if you are still learning. Olm is a major S tier for us. 

OSRS Boss FAQs

Osrs how to check boss kills

There are multiple ways to find out how many times you have killed a Boss in OSRS: The Highscores, the achievement gallery, and a Runelite command. 

The high scores: When you have killed quite a few bosses in OSRS, your boss kill count will appear in the high scores. You can also use the high scores to check how many times another player has defeated a particular boss. 

The achievement gallery: You can place an adventure log in the achievement gallery. This adventure log can be used to check how many bosses kills you have and how many slayers kills you have for a specific monster. You need 83 construction to build this adventure log in your POH. 

Runelite commands: If you use the Runelite client to play OSRS, you can use a chat command to find out how many times you have killed a boss. You do this by !kc [name of a boss]. So in practice, this would be !kc jad, if you want to figure out how many times you have fought and killed the Jad.
