Once again, I will be using my epic fire pet throughout this series unless I decide to go to a life for the much later levels.
The main strategy here, like most, was focused around the epic fire pet and the star tower. Then I just bought some ice towers to let the fire really take effect. Finally, I just added a couple fire towers at the start to make them burn the second they leave the gate. Although not all necessary, this worked well.
Hope this helped and I'll see you all next time.
