I don't know what stats this build requires. 6-7k is my stat range
First build wave, I build everything except the 2 45-degree angled DSTs and the ev phys wall and 1 reflect (mana crunch). During second build phase, sell those 3 DSTs then build 5 new as described (for stacking). Or build during the first battle wave if that's how you roll...
The 4 DU buff linking the 2 northern aura stacks can be tricky to place. You can use the place-and-sell trick with another temporary buff on each stack if you need. Or you can sacrifice the southern most reflect for an extra DU to use on that buff.
You can bring in AFKs to level during the first wave, giving them guardians (duh). If using a monk guardian, make sure it's boosting the LTs, not the DSTs.
