Build Description
First wave you will need to make the auras small so they do not get destroyed when the two outer crystals die. Boost monk with damage pet helps get past the first wave. Before second wave resize auras and traps with Jester.
Hint 1/2 - Minion stack on buff beam. Use them to make a wall so ogres do not get past.
Gas traps should be towards the back of the buff beam to help protect the lightning towers.
