Heading across the ballroom and up the stairs in the back takes you to the upper level of the ballroom. To your right on the upper level is a door that leads to a hallway of spectres of ill repute, so to speak. Fight your way down the hallway and you'll find the Maiden of Virtue standing in the room at the end. Wait, what's virtuous about a hallway of ghostly prostitutes, anyway? Killing the Maiden is an easy task at level 85. Knock her over and try not to think about the logic of Karazhan.
Tier drops The Maiden isn't interested in carting tier gear around.
Remember the upper ballroom? Head back to it and look to your right -- you'll see the entrance to the opera house, guarded by skeletal constructs. Fight your way through the trash and keep heading right, through the door and under the stage, then up the stairs and through the backstage area. After killing all the trash, you'll find Barnes the stage manager; talking to him will start the encounter. This event must be completed before you can continue to the upper levels of Karazhan. Barnes will start one of three different shows, and much like the bug trio, each show has its own loot as well as loot shared with all three shows.
Wizard of Oz Wizard of Oz will set you up against Dorothee, her dog Tito, Tinhead, Strawman and Roar. They will animate one by one, but watch out -- if you kill them too quickly, it can bug out the event. Wait for all five mobs to animate before you kill any of them. Feel free to get their health down low, but don't knock any of them over until the last mob has animated. Killing them all will start phase 2, in which the Crone will appear. Kill her for your loot -- and watch out for the random cyclones that spin around the stage.
Items of interestLegacy is a huge two-handed axe that is the epitome of Draenei weaponry. Casters may like the look of the Blue Diamond Witchwand. The Wicked Witch's Hat is a black witch hat with a purple band. And of course, the Crone drops Ruby Slippers -- red cloth slippers with an on-use effect that will hearth you to wherever your hearthstone is set.
Red Riding Hood This fight is pretty simple. Talk to Grandma to start the encounter, and she'll transform into the Big Bad Wolf. The wolf will occasionally cast Little Red Riding Hood, transforming a player into Little Red. All you can do while you are under this effect is run away from the wolf -- and it's a good idea, since the spell reduces you to 0 armor. When you change back, beat the stuffing out of the wolf. Rinse and repeat till the wolf is dead.
Romulo and Julianne These two are probably the toughest to fight, simply because of mechanics. Julianne will appear first by herself. Knocking her over will spawn Romulo. After killing him, both will come back to life -- and both must be killed nearly simultaneously. The best way to do this is to knock Romulo to within an inch of his life, then beat the stuffing out of Julianne, interrupting her heals. When she's almost dead, switch back to Romulo, finish him off fast, and then knock Julianne over before she has a chance to rez Romulo.
Items of interest Cloth wearers will love the Masquerade Gown -- a purple and gold delicately embroidered robe that is recolored mage tier 1. Romulo and Julianne also have a chance to drop Despair, a massive two-handed sword with a gorgeous model in red and silver with purple accents. Also with a chance to drop is the Blade of the Unrequited, a deadly and delicate one-hand dagger in silver and purple with a faint white glow at the hilt.
Now that the opera is cleared, you may proceed to the upper level. You can fight your way up the stairs on the other side of the opera stage and through a host of spectral opera patrons to get there, or you can zone out and take the bridge to the upper spire. There's a decrepit room here with wooden stairs going up. On your left, you'll notice a door leading out to a balcony; follow the balcony around, and you'll notice a Blackened Urn sitting on the ground. Clicking the urn will spawn Nightbane, a charred skeletal dragon boss.
Nightbane isn't particularly hard; the most difficult part is that he has two phases, air and ground. In the ground phase, he will cast Charred Earth, a ground effect that you shouldn't stand in. In the air phase, Nightbane will fly around overhead and spawn multiple skeletal adds. Both are pretty easy to handle, and aside from standard fears to deal with, Nightbane should fall pretty quickly.
Tier drops Skeletal dragons do not have the pockets required to carry tier gear.
No tier yet? No worries -- there's still half a tower to complete. Come back next week when we'll traverse the upper spires of Karazhan, pick up a couple pieces of tier, say hello to Medivh's daddy, and try to figure out exactly how Medivh managed to squeeze a dragon into an observatory.
