Crown of the Cosmos alternates a Coronation burn phase with a shielded Celestial Court add phase. Tanks trade Gravitic Crush under Weight of Rule, marked players bank Starfall scars on the rim, and the raid kills the three Crown Jewels in order to shatter the Aegis and unload during Dimmed Crown before Cosmic Scars consume the floor.
Keep the Crown near the middle with the raid loosely spread. Crowning Radiance pulses on a fixed timer; healers cover it with rolling throughput and save major cooldowns for the Court and the burn window.
The active tank takes Gravitic Crush and gains a stack of Weight of Rule. Swap after every second Crush; a tank eating a third stack during Radiance is close to unhealable.
Marked players walk to their assigned rim arc before the stars land. Stack new Cosmic Scars onto old ones and keep the center clean - lost floor never comes back.
When a Collapsing Star forms, the assigned group soaks it together to split the damage and end the pull-in. Never soak while carrying a Starfall mark; call your backup instead.
At full energy the Crown seals itself in Aegis of Stars and summons three Crown Jewels. Tanks pick up Dominion and Splendor, kicks rotate on Umbral Decree, and the raid follows the kill order while stepping out of each jewel's Shatterlight ring.
The last jewel death shatters the Aegis and stuns the Crown for 15 seconds of increased damage taken. Spend cooldowns here, then reset to opening positions before the next Coronation begins.
Treat the pulse as scheduled rolling damage. Keep the raid above the Gravitic Crush and Collapsing Star overlaps rather than reacting after them.
Failure: Spending major cooldowns on routine pulses leaves nothing for the Court, where Blinding Glory stacks the real healing check.
Swap after every second Crush. The debuff increases the next Crush taken, so the count is the plan - not health bars.
Failure: A third stack turns a routine tank hit into a one-shot, and a missed Crush splashes punitive damage across the raid.
Carry your star to the assigned rim arc and stand still for the impact. Overlap old scars whenever possible.
Failure: A star dropped in the center permanently shrinks the playable floor and ruins later Collapsing Star soak positions.
The assigned group stacks inside the star before it fully forms and splits the collapse. Personals cover the hit; the backup fills any gap.
Failure: An unsoaked collapse detonates raid-wide and drags scattered players across Cosmic Scars.
Kill Eternity first to stop Rewind Star, then Dominion, then Splendor. Every Umbral Decree gets kicked by the rotation, not by whoever notices.
Failure: Ignoring Eternity lets it heal back your kill-order progress, and a completed Decree hits the raid while it is already split.
Every jewel death sends an expanding ring from its corpse. Step out, then step back in - do not drift toward another jewel's ring.
Failure: Chained rings during the Court kill players who tunnel the next jewel through the explosion.
The named boss spells, their individual sub-abilities, and the response for each. Ability names with known spell IDs open their own WoW-God spell pages.
A raid-wide Shadow pulse on a fixed timer throughout the burn phase.
Raid response: Heal it with rolling throughput. Major cooldowns belong to the Court and the re-entry after Dimmed Crown.
A heavy strike that slams the active tank into the floor and applies Weight of Rule.
Raid response: Swap after every second Crush and use a major defensive when taking one at a stack.
Stacking debuff that sharply increases the damage of the next Gravitic Crush taken.
Raid response: The two-Crush swap cadence is fixed. A tank at two stacks stops taking the boss until it expires.
Marked players are targeted by falling stars that leave permanent void ground where they land.
Raid response: Walk to the assigned rim arc and take the hit there. Stack scars on scars.
A singularity forms, pulls the raid inward, then collapses for damage split among players inside it.
Raid response: The assigned group soaks together with personals. Everyone else plants against the pull.
The Crown seals itself in Aegis of Stars and animates three Crown Jewels around the arena.
Raid response: Kill order is Eternity, Dominion, Splendor. Tanks hold Dominion and Splendor apart while kicks cover Dominion.
An interruptible cast from the Jewel of Dominion that blasts the raid and hastens the caster.
Raid response: The assigned rotation kicks every cast. A completed Decree during the split Court is how Court phases fall apart.
Each dying jewel releases an expanding ring of arcane damage from its corpse.
Raid response: Step out of the ring, then return to the kill order. Never route through a second ring.
When the Aegis shatters, the Crown falls stunned for 15 seconds and takes increased damage.
Raid response: This is the fight's damage window. Send held cooldowns, and Bloodlust or Heroism on the first one.
Own the Crush count: swap after every second Gravitic Crush without being asked. In the Court, split Dominion and Splendor to opposite sides so Shatterlight rings never overlap the raid's kill target.
Roll Radiance cheaply, then spend for the Court - Blinding Glory ramps the whole phase - and again when Coronation resumes after Dimmed Crown. The Collapsing Star soak group needs topping before the collapse, not after.
Kill-order discipline beats meter value: Eternity first, every Umbral Decree kicked, and no cooldowns banked past Dimmed Crown. Melee should preposition on the next jewel before the current one dies.
The floor is a budget. Every Starfall in the wrong place and every panicked scatter across Cosmic Scars makes the last Coronation unplayable. Place mechanics like the fight lasts eight minutes, because it does.
