First build phase: run around with aura builder (ideally damage based, not range) to collect chests and build snare/drain on top and bottom crystals, elec and drain in the middle. When back at forge, it's faster to add the ev and app builders and then drop them out instead of running all the way back up to the forge multiple times. Build everything except the 2 DSTs marked at hint 3.
Double boost for every wave. Scimitars are essential to keep mana up for full waves.
Add app during the end of first wave, have her jump down, open the chest by the stack, and build the last 2 DSTs and then drop out.
This can easily support 6p, so duo is viable or just add a second account with 2 characters to afk. As long you have monk and initiate boosters, it doesn't matter what other characters you add, so feel free to do all monks if you want more Spear of Atlantis (trident replacement) or apps for 4 Elder Staff, or whatever mix you want. Adding the builder app does help build stability though if your stats are lower.
