Build Description
The required stats are the stats I run this with, could probably work with lower stats.
Split the LTs into two stacks and north aura stack is to the left of the crystal.
Before the first wave, upgrade the buff beam to max rank.
On the first wave use a monk guardian to boost the auras onto the buff beam.
Use two guardian summoners with huntress guardian and monk guardian on both.
For higher stats you can replace minions walls with phys beams, just sell some LTs.
