Blackrock Caverns Dungeon Guide

Blackrock Caverns is found in the Blackrock Mountain, which can be entered in Searing Gorge. The dungeon entrance is on the Eastern side of the mountain, near Upper Blackrock Spires dungeon entrance.

Here we will give you a full rundown of what you can expect from each of the bosses found here on both Normal and Heroic difficulties as well as the items they drop.

• Quake
• Chains of Woe
• The Skullcracker
• Wounding Strike

Clear the room around Rom'ogg Bonecrusher first as he will Call for Help when engaged. He will also frequently cast Quake, spawning a dust cloud underneath each players feet. This will explode after 4 seconds, dealing massive damage to anyone nearby, and spawn an Angered Earth at each cloud. Be sure to quickly move out of the dust cloud to avoid dying, and have the tank grab all of the adds and quickly AoE them down. At 66% and 33% health, Rom'ogg Bonecrusher will use Chains of Woe, pulling all enemies into melee range and rooting them in place. He will then begin to cast The Skullcracker, which will instantly kill anyone in his melee range at the end of the cast. Quickly kill the Chains to free yourselves, then run away from Rom'ogg Bonecrusher to avoid dying to The Skullcracker.

• Evolution
• Aura of Acceleration
• Dark Command
• Evolved Twilight Zealot
• Force Blast
• Gravity Strike
• Grievous Whirl
• Shadow Strike

Corla, Herald of Twilight will start the fight with 3 Twilight Zealots worshiping her. Corla will channel beams of energy into these Twilight Zealots, giving them stacks of Evolution every second. Upon reaching 100 stacks of Evolution, the Twilight Zealots will transform into an Evolved Twilight Zealot, gaining multiple deadly abilities. To prevent this from happening, a player will need to be assigned to each beam to "interrupt" it, by standing between Corla, Herald of Twilight and the Twilight Zealot. This will instead cause the player to gain stacks of Evolution, rather than the Twilight Zealot. If a player reaches 100 stacks of Evolution, they will instead transform into a Twilight Drakonid, attacking their allies. To prevent this, stand in the beam until you have around 80 stacks of Evolution, then move out until your debuff resets. Corla, Herald of Twilight herself is rather weak, with her main threat being Dark Command, as this can fear a target away from their beam and prevent them from soaking the stacks.

• Quicksilver Armor
• Superheated Quicksilver Armor
• Heat Wave
• Burning Metal
• Cleave
• Lava Spout

Karsh Steelbender starts the fight with Quicksilver Armor full stacked, reducing his damage taken by 99%. The tank will need to drag him through the flowing lava in the middle of the room to damage his armor, giving him a stack of Superheated Quicksilver Armor for every 2 seconds he is under the lava. While under the lava, Karsh Steelbender will cast Heat Wave every second, dealing more for each stack of Superheated Quicksilver Armor. Because of Heat Wave and the Burning Metal damage he will be dealing while debuffed with Quicksilver Armor, you will only want to briefly drag him through the lava to gain 1 or 2 stacks of Superheated Quicksilver Armor. If you keep him under the lava for too longer players will start dying from his increasing damage output.

• Berserker Charge
• Flamebreak
• Terrifying Roar
• Magma Spit

The room Beauty is in will also contain her 4 pups, Lucky, Spot, and Buster, which will engage alongside their mother; Runty is found in the back of the room, and should not be engaged if possible. If Runty does enter combat, you must not kill him, or this will cause Beauty to enrage and wipe your group. Use as much crowd control as you have available on the pups, killing any besides Runty that you can not CC before focusing Beauty down.

Beauty will Berserker Charge the target that is farthest away, and often uses Flamebreak to deal Fire damage to all nearby enemies. She will also periodically use Terrifying Roar to fear your group, which may cause someone to run into Runty and engage him in combat. Lastly she will target a random player with Magma Spit, dealing damage over time and splashing magma nearby, which will explode for high Fire damage to any nearby targets. Avoid the magma as much as possible while continuing to finish off the boss.

• Transformation
• Stone Blow
• Twilight Corruption
• Thunderclap
• Shadow of Obsidius

Ascendant Lord Obsidius will be protected by three Shadow of Obsidius, which can be attacked but do not take damage. These Shadows will ignore threat and only attack the player that most recently attacked them, with each Shadow applying Crepuscular Veil to their target when they get close. These should be handled by having a DPS class with high mobility or DoTs to attack the Shadow of Obsidius clones and kite them around the room, ideally using any slows available to the group to avoid taking damage.

Ascendant Lord Obsidius will swap places with one of the Shadow of Obsidius at both 66% and 33% health, so be sure the group is ready to change targets. He will also cast Thunderclap often, slowing nearby members movement speed. If the player who is kiting the Shadow of Obsidius clones gets slowed by this, quickly dispel them to allow them to properly kite. Lastly, either dispel the Twilight Corruption debuff or simply heal through it.
