The Blood-Queen is a fairly unique encounter. The gimmick here is that Lana'thel will bite one of your raid members seconds after the fight begins. Doing so will turn that player into a vampire. Before too much longer, that person will feed on another, and then that person will need to feed. This horrible pattern of events will continue until everyone's a vampire.
Like many other boss fights, Blood-Queen Lana'thel has an attack that can cause you to damage nearby allies. The range for this fight is 6 yards, but doing a range check for 10 yards is a good way to be safe -- there's plenty of room. Because of the need for distance, the best positioning for a caster is somewhere in the outer circle of the room.
