This page also contains a short overview of all world bosses in game, including those that were nerfed, removed, or just not updated for the level cap. These bosses are considered raid bosses since it takes more than a party of 5 players to down them. Blizzard seems to have lost interest for a time in the idea of world bosses as none had been added between the 0200Bc icon Burning Crusade expansion and 0500Mists-Logo-Small Mists of Pandaria.

Spawn rates

Some people have roughly estimated their spawn rates:[citation needed]

Initial spawn:

  • Tuesday Night, very late (~1-5%)
  • Wednesday Night (50-80%)
  • Thursday Night (15-20%)


  • 2 days after previous kill (30%)
  • 3 days after previous kill (40%)
  • 4 days after previous kill (30%)

Server crashing or going down counts as that world boss having been killed, and starts its respawn timer

At the time of the testing, Boss 15 Azuregos/Boss 15 Lord Kazzak used to spawn a little earlier than the world dragons. The dragons spawn one unique per the 4 spawn locations, typically all at the same time. One continent being down without the other desyncs the dragons, possibly making them spawn duplicates. (Thus occasionally spawning 2 of the exact same bosses in different locations)

History of World Raid Bosses

Originally, Boss 15 Azuregos and Boss 15 Doom Lord Kazzak were added early in World of Warcraft. They were two of the game's greatest promotions of intra-guild cooperation and inter-guild rivalry, as killing them required tracking their spawn, forming a raid, beating the encounter, AND the opposing faction (and at times same faction griefers). Their loot was also among the best at the time of their popularity.

Shortly before the Ahn'Qiraj event, the four Dragons of Nightmare were created, and added an entire new round of World Raid bosses. They were initially killed for having the best items for their slots, and later farmed for their nature resistant gear when it became apparent that some Temple of Ahn'Qiraj encounters required it. They were also involved in the Scepter of the Shifting Sands green piece questline.

As time passed, and Naxxramas came out without accompanying world raid bosses, the popularity of the world raid bosses began to fade.

With patch 2.0, Boss 15 Highlord Kruul began to terrorize Azeroth, in place of Lord Kazzak (and his Azeroth loot table).

After the Burning Crusade came out, two new world raid bosses were introduced, Doom Lord Kazzak and Boss 15 Doomwalker (there were others initially shown in databases as ?? bosses, including a rare spawn from a quest in Blade's Edge in which you can spawn a raid boss who flies away, but is unaggro-able. But currently it is accepted that there are 2 BC world raid bosses). The popularity of the two was short-lived. After a couple months it became apparent that loot off of Karazhan was on par or better, while not having the additional faction vs. faction griefing factor.

In Patch 2.2, world bosses were often left untouched for long periods of time. There were occasional guilds that use them as either practice for raiding, or under-geared guilds trying to gear up. But with a couple of announcements by blue post that they did not plan to add additional world raid bosses,[1][2] the days of a new world raid boss came to an end.

Blizzard did not add any world raid bosses for 0300Wrath-Logo-Small Wrath of the Lick King or 0400Cataclysm-Logo-Small Cataclysm.

Outdoor bosses

In 0400Cataclysm-Logo-Small some rare elites were added that were more like outdoor dungeon bosses that usually required a good 5-man group or more to kill and loot.[3] They technically were not raid bosses, but the closest since 0200Bc icon Burning Crusade to a world boss.

Dragons of Nightmare

Icon-stub-22x22 The subject of this section has been removed from World of Warcraft as of Patch 4.0.3.

These world bosses were removed from the game in 0400Cataclysm-Logo-Small Cataclysm.

Boss 15 Emeriss



Location: The Great Trees
Raid 25? (was 40)

One of the Four Dragons corrupted by the Nightmare, Emeriss is a gruesome, rotting monstrosity. Along with his AoE Sleep, he also casts a disease which damages nearby allies, and turns the corpses of the dead into deadly mushrooms. And every 25%, he casts Corruption of Earth, a Shadow DoT that deals 100% damage to the players health over 8 seconds.

Boss 15 Lethon



Location: The Great Trees
Raid 25? (was 40)

One of the Four Dragons corrupted by the Nightmare, Lethon has become exceedingly evil, enough so to darken the hue of his scales, and his eyes have also been forced open, an oddity amongst Green Dragons. He has a massive Shadowbolt Volley, and every 25% he extracts shades from his enemy that will heal him.

Boss 15 Ysondre



Location: The Great Trees
Raid 25? (was 40)

One of the Four Dragons corrupted by the Nightmare, Ysondre's once beneficial healing powers have given way to dark magics. Casts an AoE Lightning Wave that deals direct Nature damage, and summons fiendish Druids every 25%.

Boss 15 Taerar



Location: The Great Trees
Raid 25? (was 40)

One of the Four Dragons corrupted by the Nightmare, Taerar was perhaps the most affected of Ysera's lieutenants. His corporeal form has been shattered and he exists as a specter. Has an AoE Fear, and creates 3 Shades of himself every 25%.

Others - Eastern Kingdoms and Kalimdor

Boss 15 Azuregos

0400Cataclysm-Logo-Small This section concerns content exclusive to Cataclysm.


Location: Azshara
Raid 25

A mighty blue dragon who resides in the wilderness of Azshara, perusing over the countless magical artifacts there. He randomly teleports himself and all players within 30 feet a short distance, wiping aggro, casts a blizzard-like spell that eats mana, and occasionally puts up a magic reflection shield. Also, in order to prevent graveyard-zerging, he places a debuff on players that he kills. Any living players with this debuff will freeze whenever they go near him.

Boss 15 Highlord Kruul

Icon-stub-22x22 The subject of this section has been removed from World of Warcraft as of Patch 2.0.3.

Highlord Kruul

Location: Blasted Lands
Raid 25? (was 40)

Highlord Kruul is a doomguard boss who appears in various parts of Azeroth during the Dark Portal Opens event, introduced in patch 2.0.3. After the Dark Portal reopened, he officially replaced Lord Kazzak (now Doom Lord Kazzak in Outland's Hellfire Peninsula) as the Burning Legion's field commander in Azeroth, residing in the Tainted Scar in the Blasted Lands, southwest of the Portal.

He has since been removed from the game as of the release of The Burning Crusade.

Boss 15 Teremus the Devourer


Teremus the Devourer

Location: Blasted Lands
Raid 10? (no longer a world boss as of 0400Cataclysm-Logo-Small Cataclysm)

Teremus was an immensely powerful black drake found in the Blasted Lands. He had an AoE Lifesteal, and wipes aggro when he uses a knockback attack. When he gets down to 20% health, he regenerates to full health, making him one of the most difficult and prolonged fights in the game.

He used to be a popular target for the makers of machinima, most frequently being kited by a hunter and a priest from the Blasted Lands to Stormwind or Ironforge, but as of some past patches, he is now chained to the Blasted Lands and will leash back when a player tries to kite him out of the zone.

Event/Quest - Eastern Kingdoms and Kalimdor

Boss 15 Omen



Location: Moonglade
Raid 25? (was 40)
Omen is a demon boss summoned in the Moonglade during the Lunar Festival.

He consumes the soul of all beings he slays to heal himself, casts a curse on players that makes their mana pools combust and if he isn't killed in 3 minutes, goes into his "supreme mode," allowing him to completely obliterate everything in his path.

Boss 15 Doomwalker

0200Bc icon This section concerns content exclusive to The Burning Crusade.


Location: 0200Bc icon Shadowmoon Valley - In front of The Black Temple
Raid 25 (at level 70)

  3. ^ Blizz Valnoth 2010-10-26. #7 - Thank you for the outdoor raid bosses. Archived from the original on 2010-10-26. There are a COUPLE of these bosses in Cataclysm, but they're not true outdoor raid bosses. They're just much harder group bosses that drop heroic dungeon level items and specialty items. Have fun!
