Low stat variation on M4tt's infested build, split the lt's (15 total) in 3 stacks of 5 so each stack can be fully buffed by a boost summoner with a hunt and monk guard.

Make sure you upgrade the traps enough so they last through all the waves (I upgrade them 3 times). Summoner positions are the same as m4tt's build, top of the stairs (lt's at the bottom) to avoid wasps hitting your towers. Make sure that you buff the auras with your monk guardian at the start of the first wave so they are on the buff beam, this is very important and YOU WILL LOSE IF YOU DON'T. With these app stats the east darkness trap can also get desummoned occasionally, this won't lose you the run but i recommend rebuilding it the next build phase as it does make the run faster. Also make sure u start around wave 20/21 as you will want to fully upgrade all the towers and minions before wave 24. when you're done upgrading (which I reccomend you do with 2 summers and your upgrader in the game) you will want to swap the upgrader for the third guardian summoner. You don't really have to do much after upgrading, just make sure you flash heal after each wave (not really necessary early but it is for the later waves), enjoy.
