You can burn it but not easily. She has a ton of hit points for a group mob and the adds make it difficult. At around 50% or so, she ports downstairs and takes your tank with her. Your dps will likely want to follow her and then after a bit she ports back up and your dps has to run back up. At 30% health, she casts one of three debuffs on each of the group members. One debuff drastically multiplies the damage you take, one reduces healing, and the other drops your dps if I remember right. If you cast a high level disease cure, you can toggle between the three. So the key is getting the correct debuff on each of your group members. If your tank gets the first one and doesn't change it, you'll wipe. Getting some disease cure potions and creating some holyshits/downshits is probably the best way to approach this. Seriously, read the comments section on the fight at Eqresource and work out a strat that will work for you. What works for me will likely not work for you. If you still struggle with it, my suggestion is to break your group down and box fewer characters and get some friends to join you. Having six real players makes this event easy. Boxing six is damn hard.
