Easiest thing to do is just to run/pull mobs into the lamplight as they pop up and move around. The adds from coffin are quite wimpy - was able to tank Ashanti and adds quite easily. With that said, this was tough to duo with shammy/pally; at the last 20% things would go a bit haywire with directional AE and add from coffin. Task is not meant to be done by botters really. Added a 3rd real player/toon and it was a cake walk.
