Build Description
Nice and simple.
Stacking
You want to have the side crsytal towers farther away than you expect. Not at all inside the circle. Ogres will hit the crystals. If these placements don't work then try closer to the edge of the map.
White djinn can be ignored as the towers will kill.
I used a monk for the boss kill with an okay mm and wizard.
if it doesn't work, you can throw in some ogres but it was completely unnecesary hope this helps people with the solo clear. ;]
