Ar'ticae's Lair  

This zone works very similar to the non-raid zone.

Upon zone-in, you need to clear all the entrance trash as quickly as possible as it has fast respawn timers. Once that's done, go into the left room and kill everything in there. This will unlock the right-hand room, so run over there to kill everything in there too. Be aware that the trash in the front room might already be up again, so you may need to kill this once more. Once everything in the right hand room is dead, the middle door will now unlock. Again, be aware of respawned trash.

Go through the middle door and just slaughter everything you can on the way to Ar'ticae herself. For her, you want your MT to rush her and tank with his back to the wall. The rest of your raid force wants to be on the side of the room nearest the door. This should avoid her frontal AOE and any potential knockback. Just burn her down nice and quick to finish the encounter. There should be no more nasty surprises.
