WoW Crucible of Storms: Raid Guide for All Difficulties
Crucible of Storms is a two-boss raid released with patch 8.1.5 in Battle for Azeroth. You find the entrance in Stormsong Valley, and the whole place revolves around the Old God N'Zoth and his influence over the Tidesages. The raid is short, usually cleared in 20 to 40 minutes on Normal or Heroic, and it supports flexible groups of 10 to 30 players.
WoW Crucible of Storms at a Glance
The raid has four difficulties: Raid Finder, Normal, Heroic and Mythic. Normal and Heroic scale between 10 and 30 players. Mythic is fixed at 20. Both bosses drop gear from the 8.1.5 tier, with item levels around 370 to 385 when the raid launched, though modern scaling now makes most of it obsolete for current progression.
Today people run it for transmog, achievements, and a fast weekly kill. The setting is small, and the fights are quick.

Crucible of Storms Mythic: Boss Tactics
The Restless Cabal
This is a council fight against two priests, Zaxasj and Fa'thuul. Each phase of the fight gives one of them the spotlight. Zaxasj summons Crushing Grasp tentacles and mind-control effects, while Fa'thuul pushes Void-based spells that need spread positioning.
On Mythic, the dangerous mechanic is Agent of the Deep, a debuff that forces the affected player to step away from allies. Assign two or three people to handle adds quickly. Dispel Shadow Mend casts when you can, because they heal the cabal faster than raw damage can keep up with.
Uu'nat, Harbinger of the Void
Uu'nat has three phases and a hard enrage timer around eight minutes on Mythic. In the first phase, the tank swaps at around three stacks of Gift of N'Zoth. The second phase brings Void Crash, which punishes anyone standing in the middle of the room.
Use your raid cooldowns at the transition into the final phase. Most failed Mythic attempts come from poor positioning during the Trial of Servitude mechanic, not from low damage. Keep one player on each side to soak the orbs and cover for deaths.
Loot, Mounts and Transmog
The raid drops a handful of tier-appropriate weapons and trinkets, but the real draw is cosmetic. Uu'nat drops a unique transmog set and the Shadowbarb Drone mount is tied to the later Eternal Palace content rather than here. If you want the rare ride tied to this story arc, check the nzoth mount route, since it comes from Visions of N'zoth and not from this raid.
The achievement Ahead of the Curve: Uu'nat, Harbinger of the Void is awarded for a Heroic kill. Cutting Edge needs a Mythic kill before the next tier opened, so it is no longer obtainable.
Crucible Boosting Service: What to Know
Many players search for a crucible boosting service to pick up the Mythic transmog or the old achievements. Because the raid is small and outleveled, groups of friends or guild members can clear it with little help. Paid carries in the community exist, but expect to pay roughly 100,000 to 400,000 gold for a Mythic run, and always check that the seller uses an in-game trade rather than asking for your account details.
Never share a password. A legitimate carry only requires an invite and a trade window. If you are looking for a bigger target, a bod mythic carry is more common than anything for this raid, since Battle of Dazar'alor has more value to sell.
Where It Fits in the Eternal Palace Storyline
The raid is a short prologue to the Nazjatar campaign. After you finish, the story moves on to wow eternal palace, where Queen Azshara waits and the full 8-boss lineup starts. Clear Crucible first if you want the lore in order, because it explains why the Old God corruption is spreading through Kul Tiras.
