Pretty quick easy/clean build.  Faster to hunt Jester Guardians on NM (and lower level final wave).

Building right next to the forge.  Couple monk auras.  4 DSTs--one in each direction.  6 LTs. Small pile of hermit stuff as back up when things get close.  All on a boost beam.  Uses the default DU cap of 115.

Fully load it with players at start; 3 summoners (2 of each guardian pet types, huntress, monk, apprentice) and then use Tower Boost monk near the stack to upgrade/boost and keep the fires going, pew pew pew.  Alternately, if stats are high enough, just skip the Tower Boost Monk and bring in an upgrader 1st wave, then a 4th summoner to collect armor drops on your runs.

Can 'probably' drop all the hermit stuff, but it's habit for me now, so I keep it.  

Trivia:  As of this writing I still have not seen a tier 6 Jester Guardian roll for me, but I've gotten about 20 Tier 5's, so still chasing it.  I will continue to hunt.
