Two phase fight. In P1 you fight Diurna and deal with regular waves of multiple different adds that spawn in groups.
In P1, split your raid in 2. One group deals with the boss and destroys the eggs. One group deals with the regular waves of adds. Keep the boss and the adds far away from each other.
In P1, constantly move Diurna near new eggs and use the beams of her staff to destroy them. When all eggs have been destroyed, or after 5 minutes, P2 starts.
In P2, adds stop spawning. There's only Diurna left and she deals increasing damage. Diurna cannot die until all eggs have been destroyed.
Wildfire now also launches small projectiles around the point of impact. Dodge those as well.
Diurna regularly fills ALL the trajectories of all the beams used to destroy eggs with lethal lighthning. Don't stand in it.
Hatched eggs by Rapid Incubation now spawns one add from the regular waves instead of a baby dragon that does nothing. The color of the egg determines which add it is. Don't let them hatch, or it's a wipe.
Every 7s spent in Diurna's range, your damage vulnerability increases by 1%. The group that stays on Diurna for the whole of P1 will take more and more damages during P1.
P2: The boss now applies a bomb on the tank that needs to be soaked when it expires. With the recent nerfs, tanks can solo soak them with an external defensive CD.
Groups of adds constantly spawn and need to be killed. Keep them 50yd away from Diurna and split your raid in 2 groups. One group deals with the boss while the other deals with adds.
Use the staff from the boss to destroy the eggs in the room. When all eggs have been destroyed, or after 5 minutes, P2 starts.
EVERYONE
DON'T STAND IN THE LIGHTNING
THAT FALLS ON THE PREVIOUS
BEAM TRAJECTORIES.
Diurna remembers all the trajectories from all the beams of her staff used to destroy eggs. She regularly fills all those trajectories with lethal lightning. Don't stand in it.
EVERYONE
LOCATE AND DESTROY THE
HATCHING EGGS TO AVOID
DEALING WITH ADDITIONAL ADDS.
Regularly, the 2 eggs closest to the boss are marked and will hatch, spawning an add, after 15s if not destroyed.
On Mythic it spawns one of the adds from the regular waves, the one corresponding to the "type" of the egg. If one egg hatches, it's a wipe, the add will be buffed and kill you all.
EVERYONE
USE THE BUTTON TO DESTROY
EGGS WITH THE BEAMS.
PRIORITY ON HATCHING EGGS.
After each Rapid Incubation, Diurna plants her staff into the ground and gains 3 stacks of a 10% damage done buff.
Players can use an extra action button when next to the staff on the ground. Using the button will cause a beam to follow that player, dealing damage to anyone hit and destroying any eggs in its path. 1 stack is removed on the boss per use.
When an egg is destroyed, the boss deals a burst of raid damage and inflicts 275% more damage on the same burst for 10s. Don't destroy more than 3 eggs at a time.
EVERYONE
SPREAD OUT
DODGE THE SWIRLS
WATCH OUT FOR NEW SWIRLS
Mythic Changes: Upon explosion, several small AoEs are also thrown around each player.
Marks all players with a circle that will drop a swirl at their feet and apply a DoT. Being too close to another player will give both players 2 DoT stacks.
The swirl will explode after a delay.

SPREAD WHEN TARGETED

THE TURNING FIRE BEAM
IS OBVIOUSLY NOT A BUFF.

BABY DRAGON GOING
CRAZY IS OKAY. IT JUST
DEALS DAMAGE AND SLOWS.
Cast by the Juvenile Frost Proto-Dragon (different from the baby dragon spawned from hatched eggs).
Deals damage every 1s for 6s to players within 50yd and slows them by 10%.
When Diurna plants her staff into the ground, after each Rapid incubation, the staff deals pulsing raid damage.
The boss has a 50yd aura which buffs the damage of nearby adds by 50%, gives them a 25% damage reduction, and heals them. Keep the boss and the adds far away from each other.
Split your raid into 2 groups. 1 tank, a few healers, and dps deal with the boss and destroy the eggs. The other half deals with the regular groups of adds that spawn in corners of the room.
The raid takes a burst of damage, a 30% snare, and a large dispellable heal absorption shield.
As long as the heal absorption is up, players take heavy ticking damage and are snared.
This add is part of the regular waves of adds in P1 (different from the baby dragon spawned from hatched eggs)
Presented above. Deals damage every 1s for 6s to players within 50yd and slowing them by 10%.
Each active egg makes 2% of the boss' health immune to damage. Destroy the eggs to kill the boss.
Mythic Changes: The 10% vulnerability is increased by 1% every 7s. You still keep one group on Diurna for the entirety of P1, and the other group deals with the adds.

Players more than 50yd away from the boss move 15% faster.

TANK SOLO SOAK THE EXPLOSION.
USE AN EXTERNAL CD TO HELP
THEM IF NEED BE.
Diurna now also leaves a bomb on the tank when she uses Mortal Stoneslam. Upon expiration, the bomb inflicts damage split evenly between all players in it.

KITE THE BEAMS INTO
THE REMAINING EGGS
OR AWAY FROM ALLIES.

HEAL, DAMAGE, DISPELL THE ABSORPTION
SHIELD TO PREVENT MORE DAMAGES
AND REMOVE ROOT.
The raid takes a burst of damage, a root, and a large dispellable heal absorption shield.
Healing or dispelling the heal absorption removes the ice. Destroying the ice removes the heal absorption.
As long as the heal absorption is up, players take heavy ticking damage and are rooted.
A general WeakAura pack that provides "icon" style mechanics/debuff as well as short descriptions for each. Pretty standard. We also recommend downloading Causese Sound addon to hear vocal announcements. Feel free to thank the amazing Causese here (sorry, no Twitter that I know of).
Another must-have by Causese if you play or are planning to play tank. It informs you when to taunt and how your co-tank is doing with their mechanics.
Make sure to checkout the Causese Sound addon to also pair it with appropriate sound announcements.
