A variation of the other build, this time minus the DPS summoner.
Everything needs to be max upgraded. I equip my upper Jester with a chicken baller for this map. I don't know what stats are needed, but if you don't have enough damage and tower health, this build will not work. With my stats, the auras should at most reach 1/4 of their health on the last wave.
Hint 1
Summoner with App/Huntress.
Build the tower stack on the small pillar.
Hint 3
Summoner with App/Huntress. This Summoner should be boosting the Forest Golem as well.
Place the SAMs pointed north so that one line of the angle marker is parallel to a line running directly west to east. In other words, the SAMs will be pointed more towards the north than they are to the east or the west.
Hint 4
Summoner with App/Huntress.
The Shroom Pit and Forest Golem is placed on top of the boxes as far as possible from the Reflect Beam. This is avoid the stack getting webbed by a spider.
