Works with both NM and RL, NM runs are 13 mins and RL are 22 mins
Green arrows are mortar directions.
Green bars demonstrate the cutoffs for mortar angles.
Reflects are around the square.
Bulwark is inside the EV walls. (It'll pull aggro if a wall goes down mid fight.)
Build everything except golem, both guardian towers, and EV walls first wave.
TB monk and use an upgrader, once everything is upgraded swap out your upgrader for a ranged DPS and 2 summoners. One with huntress/squire that sits on pin 2 and another with hunt/app that sits on pin 1. (HB monk instead of summoner might be good too.)
I didn't use a healing aura, instead I just rotate flash heals. If you decide to use a healing aura then delete the trap.
Screenshot is without golem and reflects to show positioning.
