Scarlet Halls is a dungeon whose entrance is located in Tirisfal Glades in the World of Warcraft game. The minimum level for this dungeon is 90. The main anagonist race in this dungeon are Human. The instance was released in the Mists of Pandaria expansion. The dungeon contains 3 bosses. The end boss of Scarlet Halls is Flameweaver Koegler.
Scarlet Halls and Scarley Monastery are two dungeon instances located in the Scarlet Monastery in the north eastern section of Tirisfal Glades, home and starting zone for the Forsaken zombies.
In times before Looking For Group (LFG), Alliance groups would have to make their way to the Monastery and avoid being killed by the enemy. LFG made things a lot easier.
Scarlet Monastery used to be three dungeon instances before Mists of Pandaria expansion which revamped the dungeons and reduced it from three to two. The number of bosses were reduced in each section.
Scarlet Monastery is the home of the Scarlet Crusade, a bunch of religious fanatics that are holed up in Tirisfal Glades predominantly and who are obsessed with seeking the destruction of the Forsaken. As they have lost their way, they have turned against the Alliance which has resulted in everyone wanting to kill them.
The Scarlet Crusade can also be located in Desolace zone where there is an emissary who is friendly to both sides. They can also be located on the continent of Northrend where you are required to undertake missions in the area.
Braun appears in the middle of the courtyard where he attempts to call you out. Round the outside of the room are his pet bulldogs. During the fight, he'll call on a bulldog to intervene. When the bulldog does intervene, you need to switch to the bulldog and kill it.
At the end, Braun starts to bleed and that is when the dogs will turn on Braun and finish him off. If you are hard enough, ignore the dogs and do full on nuke on the Houndsman. Once the dogs have finished their meal, they will force open the route for you.
Armsmaster Harlan is an optional boss but most groups will kill him for the loot he gives. When you arrive in the room becareful getting into position in case you accidentally start the fight.
During the fight, he'll call upon two Scarlet Crusaders which when you hit them, they'll become naked bar their underwear. Soon after they become naked, he'll start spinning on the spot, this is the time to get out of the way as he will turn into a fire cyclone and suck you up. He'll spin up and then down the stairs. When you are caught in the firestorm, you will not be able to do anything. You will have to wait until he releases you.
In the final room, Koegler is praticising his fire skills until you get close enough to start the encounter. The main things to be aware of are Book Burner and Greater Dragon Breathe.
Koegler will send a fireball into a bookshelf and start it a light. The burner bookcase will throw out lots of flames but are easy to avoid, you just have to avoid them.
Greater Dragon Breathe is where he'll spin on the spot and spout flames like what you saw when you first entered the room. For both spells, you need to move out of the way.
