Hello

Went into Karazhan here are my results:

Opera boss: in EU looks like we got Beautiful Beast this week, was pretty easy fight with some AoE that CC you, some fire on the ground and lots of stuff to interrupt, poped all my cds hoping to cleave them down but ... once they all were 10% and i killed one .. rest of bosses gained full health.. So in short u gotta nuke one by one.

Attumen the Huntsman: took me few tries, I did not switch any of my paladin spec to holy I did it as x5 prot, got Potion of the Old War for this one for more burst damage, saved my CDs and Drums once he jumps from horse I used all and burst as much I could, almost got him in 1 try, Divine Shield helped with Spectral Charge at the end where I had no place to run, one of easiest fights I would say.

Moroes: nuked Keria as first and just cleave AoE down the rest, all of them died before even my CD's has ended, then it was just tank n spank, easier than Opera fight.

The Curator: had some wipes at start, I decided to save my CD's for Evocation phase and just keep moving all the fight, got him on his 3rd Evocation phase, at start of it, he was about 5% when it start to cast.

Shade of Medivh: heeeere is where fun starts for me so I read
Shade of Medivh is probably the easiest boss in this dungeon and I was able to 1 shot it.
I didnt even go read boss abilities and just go try to kill him .. it was easy before he cast Ceaseless Winter and I didnt know I gotta move to remove stacks, I did wipe few times on Flame Wreath aswell .. once my Divine Shield didnt go off GCD as I was smashing my rotation and pressed it a bit too late, I would say it took me over 10+ tires, ended up killing him with 3 toons alive.

Edit: Forgot to say I had 1% wipe on this boss before I kill it

Tips: use Ardent Defender for Flame Wreath then heal to full with Hand of the Protector, I did not test Blessing of Spellwarding for it, I guess it should work as its magic damage, on Winter phase make sure to interrupt frost cast, once he freeze your toon it will start taking lot of dmg because you cannot move it around to remove stacks.

Im probably gonna give few tries on Mana Devourer before I stop for today. Will continue tomorrow as I got some other things to do and its been few hours in Kara already.
