Phase one remains the same as on normal mode, except that the adds spawn faster, have a lot more health and do a lot more damage. The same goes for the boss. Thank god her shield stayed the same, the hard thing for some people seems to be not falling asleep during phase 1, it can become quite boring after a couple of tries.
Once the shield is down on good timing to get rid of adds quickly as she breaks the real fun starts. Adds keep spawning in phase two, luckily it’s only 3 at a time instead of 7. The best thing to do is bring the caster adds close to the boss so they die quickly and have a warrior tank with piercing howl kite the melee adds, a la Razorgore.
The real problem seemed to be ghosts however. She spawns her little ghosts as always, except now if they touch you they explode in your and everyone else in a 20 yard radius’ face for 25k!
To deal with the ghosts simply run away from them, they exist for only 5 seconds, then they despawn. But people seemed to have problems seeing them at first, luckily after some tries we figured out how to spot and avoid the ghosts, finally resulting in a kill!
