Build Description
Hint 1: This buff beam can be the minimum size; the monk auras should overlap it and there's room for two minions.
Hint 2: because of the lump in the floor, you can only really make this buff beam long enough to connect the LTs and everything between them (the mage minion is actually aside from the others a bit and isn't covered, but some clever maneuvering might fit him in).
Hint 3: As you start getting more enemies in each wave, these auras (strength drain in particular) will drain fast. Make sure you're staying alive and on top of repairs or you risk having to rebuild your aura and the buff beam!
