We tried one time and didn't quite understand what to do and then got it on the second time. We had 5-6 people there. Several stood under the platform shooting the eyes and normal ogres, while others ducked behind the rocks DPSing the Servile Ogre as best as they could. Upon taking down the Servile Ogre, we all bum rushed the Wizard with our supers -Nightstalkers and Storm Callers- and heavies. Swords are great for the wizard portion, but everything works. You have to kill the wizard quickly or the Servile Ogre respawns, so take the wizard down as fast as possible. Try to have a few higher light level players when you try it. One friend -who had the antiquated rune- was roughly 250 and barely did any damage to the yellow bar enemies.
