Heroic Changes
In P1, breaking an egg inflicts a burst of damage to the raid and applies a 10 second 200% vulnerability to this burst. Don't burst more than 3 eggs at a time.
In P1, the Wildfire debuff on players now also gives stacks to nearby players. Make sure to spread! In P2 she casts 2 Wildfires back to back, dodge twice.
Most adds gain an extra ability. You can read through them below.
Mythic Changes
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.

Broodkeeper's Bond: Add Buff

https://www.wowhead.com/en/spell=375809 - 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.
keep the adds far away from the boss

baby dragon going crazy is okay. it just deals damage and slows.
