Just I had a 58lvl new dd spell from Ayu that i decided to give it a try and also I had "gathering mana" aa which provides me another full bar of mana to do the dmg so.
No secret that all I did is dd>dd>dd but, in case of I dont get too much attention from AOW that I had my lowering aggro aa fully trained and I covered myself with Glamorous Visage(lowering aggro buff) during the whole fight and I'd always kept 20% of mana for spare for rebuff
