World of Warcraft Top 10 Bosses of All Time

If you’ve been playing WoW for a long time, chances are, you already know the best and most memorable bosses in the game.

You know, the ones that had you pulling your hair out in frustration. Don’t worry, we’ve all been there.

So to take you down memory lane, here are the best WoW bosses of all time you’re sure to never forget.


The final boss for the raid of Blackrock Foundry, Blackhand is a three-phase encounter that is primarily single-target as well as the final boss for T17. In this battle, you have to go through a 3-phase encounter where, along with Blackhand, you’ll have to face many environmental tests and adds that need bursting down. As such, it calls for moderate to heavy movement, raid awareness, and quick execution of key mechanics by you and your team.

Lady Vashj

Lady Vashj is the final boss of Serpentshrine Cavern in Coilfang Reservoir. Before, players are required to defeat all prior bosses in order to unlock her. Now, you can battle Lady Vashj without having to clear the instance. This is an adventurous raid in general, and a battle for survival which tests the raids capability to function as a team. The tokens you can get after defeating Lady Vashj are Helm of the Vanquished Champion, Helm of the Vanquished Defender, or Helm of the Vanquished Hero.


Residing in the Molten Core deep within Blackrock Mountain, Ragnaros the Firelord is an incredibly powerful elemental lord and ruler of all fire elementals. Your goal is to get him down to 30%-40% before the first wave of sons, to be able to kill him before the second. This is particularly hard, considering this Molten Core boss has several abilities which he uses during battle, such as the Wrath of Ragnaros – Melee Knockback, Hammer of Ragnaros – Ranged Knockback and Damage, and Lava Splash – Localized Damage among others. Ragnaros has a low chance to drop Eye of Sulfuras, the key ingredient to making Sulfuras, Hand of Ragnaros.

Kael’Thas Sunstrider

Lord of the Blood Elves and the final boss encounter of the Eye in Tempest Keep, Kael’thas Sunstrider is definitely one of the most unforgettable and hard to beat bosses in WoW. In fact, the battle with Kael’thas covers a total of five difficult phases – with the starting phases being a bit of a DPS race and the later phases showing a highly powerful Kael’thas. He is accompanied by his council of four advisors and known for spawning seven powerful legendary items that you have to fight, defeat and then equip in order to face Kael. He is also known for dropping Ashes of Al’ar, one of the most popular mounts in the game.

Illidan Stormrage

Considered a legend when it comes to WoW bosses, Illidan Stormrage is the final boss of the Black Temple and the twin brother of Malfurion Stormrage. The key to success in defeating Illidan, which raid consists of five phases, is good positioning. You’ll have to be at the right place at the right time in order to win over him. He drops two legendaries: Warglaive of Azzinoth and Warglaive of Azzinoth.

Imperator Mar’gok

Imperator Mar’gok is a two-headed ogre and the final boss of Highmaul Raid. With a watchful eye and an iron grip, he rules the Gorian Empire and oversees the Highmaul Coliseum. The Mar’gok encounter consists of four long, complex phases along with 2 transition phases. It’s a quite a complex raid, with Mar’gok starting the fight with a certain set of abilities which he empowered with activated Runestones. While Mar’gok is a hard boss to defeat, you’ll only need to pay attention and observe as he tends to use the same sort of abilities and spells with only slight modifications.

Operator Thogar

Another boss in the Blackrock Foundry is Operator Thogar, specifically in the Iron Assembly Wing. He’s not known for brute strength but famous for his cruelty and cleverness. Thogar is a train operator and oversees the operation of the Grimrail, coordinating the ongoing ground battle against the draenei in Talador, with entire battalions of troops and artillery under his command. Another thing you should know about Thogar is that he tends to crush the raid members with trains coming from nowhere. Which makes the raid strategically tough.

The Lich King

Who will ever forget the boss of Icecrown Citadel “The Lich King?” This boss is one of the reasons why World of Warcraft: Wrath of the Lich King turned out to be one of the best expansions from WoW ever. Battling this boss is definitely hard. You and your team need to have quick responses to different spells from the Lich King. That’s because a single mistake from a team member would result in an entire team wipe. And that’s something you don’t want to happen. Once you killed him though, you will gain 1,500 reputation with The Ashen Verdict if Normal, and 3,000 if Heroic.


C’thun is the final boss in the temple of AhnQiraj. Known as the ugliest eye ever, C’thun was considered the most difficult raid boss and practically unbeatable in the game for a very long time until the release of the original Naxxramas and later The Burning Crusade. During the initial phase, he uses his abilities in battle, including Eye Beam (Green beam), Dark Glare (Red beam), Eye Tentacles and Claw Tentacles among others. All of which provide a great deal of damage when used. Fortunately, this boss is much more controllable in the final phase.


M’uru has proven to be an extremely hard boss to kill, earning the top spot in this list. He managed to provide a very difficult DPS battle to the raid. It was almost impossible to get through that no raid has ever survived M’uru without a Protection Paladin on their side. Even so, the entire DPS team still had to be divided into groups in order to burst equal amount of damage. The spawns and sentinels are definitely not helping. In the early years of WoW, M’uru was basically an unkillable machine. But after a few changes, it was manageable. But just barely. Players still find it hard to bring M’uru to the ground.
