works best with a REAL E/Me AE spec, first part of the mission where you have to kill the mobs infront of the keep. There is a lever to open a door, press it, then hide id the corner behind Prince...then wait till they charge in and start attacking him, when they are ontop of him must attack quickly Cast: Fire Storm, then the Mesmer AE spell, and i use the glyph eaither before or after Fire storm, and just start attacking with fireballs at the mobs while they are dieing.
Or to do it quicker is use the Lava font spell while the other 2 are going off and boy do they die fast. usually get xp VERY fast if low lvl or solo. and drops rares and runes sometimes and good salvage and can do over and over
