‘Even as Legion troops patrol the streets, casting a pall over the grand city of Suramar, the socialities of the Nightborne nobility continue to cling to custom and routine. On this clear night, the cry of revelers echoes through the chill air, as the largest mansion in the Noble District opens its doors for a grand gala. Rumor has it that Grand Magistrix Elisande herself may be making an appearance, in an effort to reassure several of her closest allies despite recent turmoil.‘
The new Seasonal Affix for Dragonflight Season 1 is Thundering.
Throughout the Dungeon, Thundering spawns blue voidzones on the floor that must be avoided by players. Additionally, all players will be affected by a certain buff, that increases their damage and healing done. Three players in your group will be affected by Mark of Lightning, while other two players are affected by Mark of Wind. Tanks will always be affected by Mark of Wind. Coming in contact with the opposite debuff will clear this debuff. If not cleared by walking over a player with the opposite buff will cause the players to be stunned for 8 seconds, taking heavy lightning damage over 8 seconds.

The first Boss you will encounter in Court of Stars is Patrol Captain Gerdo. In Court of Stars, many of your professions will be able to grant you additional perks you can use during this dungeon.
As soon as you start the dungeon, talk to the Signal Latern to order a boat that drives you to the next location.
Whenever you travel further to the first Boss, you will encounter multiple Arcane Beacons. Duskwatch Sentry will attempt will cast Sound Alarm, running to the Beacon. If this cast is successful, it becomes Secured.
Player’s must deactive them in order to avoid the first boss Patrol Captain Gerdo to spawn additional reinforcement during the encounter.
Guardian Constructs are located throughout the the Gilded Market, and pack a few abilities.
These can be deactivated by Engineers, Goblins and Gnomes by clicking the Arcane Power Conduit. This Ball is located in the House to the left of the bridge, crossing the river to the first boss.
You will encounter a few Mana Wyrms which leave a Voidzone on the floor on death.
Mana Saber leaps to random party members and uses Mana Fang to deal heavy AoE damage in a 5-yards radius.
The first Boss in Court of Stars is Patrol Captain Gerdo. Make sure to deactivate all 3 Arcane Beacons to prevent the boss to summon additional adds during the Boss encounter.
Before the Boss fight, Rogues and Alchemists can poison the flask that Patrol Captain Gerdo drinks during the fight to instantly kill him.
‘Captain of the Duskwatch, Gerdo has devoted his life to keeping the peace within the walls of Suramar. Though he has a growing unease since the arrival of the Legion, he remains faithful and loyal to the leadership of Suramar. Elisande has safeguarded them for generations, and she knows what is best for the people of the city. Tonight, Gerdo’s task is to ensure that only citizens with the proper credentials are able to enter a gathering of particular importance at the manor.’
Players that are Alchemists, or Rogues can click the Flask which the boss will drink during the fight, in order to instantly killing him and saving your group a lot of time.
It is really important to note again that players have to deactivate all Arcane Beacons in the Gilded Market. Otherwise, the Boss will spawn reinforcement during the encounter which will cast Hinder, stunning random players for 6 seconds.
Frequently, the Boss will spawn a beam Streetsweeper, dealing heavy damage to players stuck, which can be dodged by walking out of it very quick.
The Boss will use Resonant Slash, aimed towards the Tank. This will spawn a cone infront and behind the Boss which deals heavy damage and stuns players for 4 seconds if hit.
The Boss will apply Arcane Lockdown to all players, a debuff that inflicts periodic damage aslong it persists. To remove a stack of this debuff, players have to jump! This debuff cannot be removed by moving your character. This debuff will deal heavy damage as long it persists and slows your movement speed, which makes it very difficult to dodge Gerdo’s other abilities.
At 25% health, Gerdo runs to the Flask of the Solemn Night, granting him 30% Haste and 30% increased damage. If this Flask has been poisened by Rogues or Alchemists, the Boss will instantly die.
After defeating the first boss Captain Gerdo, you have to fight your way trough the Midnight Court in order to slowly eliminate the adds protecting Talixae Flamewreath. If not, they engage into the Bossfight and deal more damage and increases their healthpool with Bond of Flame.
In order to engage every single Demon protecting Talixae Flamewreath, players have multiple creative options to achieve them getting seperated.
Defeating a Felbound Enforcer will trigger one of the demons protecting the boss to run to the location where the Enforcer died. Those Enforcers are indicated on the Minimap.
They will cast Fel Detonation, dealing heavy damage to the entire party and leaving a debuff dealing even more damage. This can be avoided by tanking this Enforcer at a corner, so players can quickly Line of Sight this cast before it goes off.
Each demon protecting the boss has a unique ability that
players need to deal with.
Players can also trigger these demons to engage by different Class/Profession-based perks.
After eliminating all Adds protecting Talixae, you can finally start the encounter with the second boss of Court of Stars.
‘A sadistic eredar sorcerer, even as she understands the importance of the nightborne to her master’s plan, Talixae chafes at the indignity of standing guard over a building full of elves. Nevertheless, she and her lieutenants remain vigilant, and while they live, no intruders will disrupt the gathering.’
Most important Ability of this boss fight is Infernal Eruption. This spawns a pool of fire below each player, out of which an Infernal Imp spawns. This Imp has to be killed, otherwise it attacks random players with Firebolt and Drifting Embers. Keep in mind that the pool of fire on the floor deals damage to all players standing in it, so you want to position your group close to each other in order to kill those Imps very quick.
Burning Intensity is unavoidable damage and has to be healed off by the Healer in your group. This damage increases over time, the more stacks Talixae receives.
Talixae Flamewreath will cast Withering Soul in the attempt to reduce all players maximum health by 5% per application. This must be interrupted.
After defeating Talixae Flamewreath, its just a short way to the final boss of Court of Stars – Advisor Melandrus. Talk to Ly’leth Lunastre in order to receive your Masquerade illusion, which grants you entrance into the Jeweled Estate.
While you are in the Jeweled Estate, you will find many NPC’s that you can talk to. Your Goal is to find the spy which will walk you into a secret room when the spy transforms into a Dreadlord.
You have to talk to all 5 NPCs marked on your minimap in order to get all clues of who is the spy.
Addons like Deadly Boss Mods or a Demon Hunter using Spectral Sight after talking to all NPCs will make your life way easier.
As soon as you found the correct spy, he will make you follow him to a secret room. The spy will transform into the Dreadlord Gerenth the Vile, which drops a key on the floor that must be picked up by players in order to unlock the room to the last boss Meladrus.
Blade Surge will target a random ranged player. The boss will charge to the indicated location, and leaves an Image of Advisor Melandrus on its location. Additionally, this deals heavy damage whenever a player gets hit by it.
Range players could potentially coordinate the location of this, so other abilities are easier to handle with. Standing close to an Image of Advisor Melandrus has no effect, and players are free to position themself ontop of them.
The most dangerous ability is Piercing Gale. This will deal damage in a straight line infront and behind the boss, and every Image of the boss.
If ranged players positioned themself ontop of old Images, this will allow players to easily dodge this ability. Otherwise, this can become very difficult to avoid. Getting hit will knock players away and deals heavy damage.
Use your strongest damage cooldowns and Bloodlust on this Boss.
The Boss will spawn Enveloping Winds frequently. Those Tornados are travelling trough the room, and stun all players coming into contact with them.
The Boss will use Slicing Maelstrom, a strong AoE damage that cannot be avoided. This damage becomes more and more deadly the more Images of Advisor Melandrus are alive, echoing all of his abilities.
