Stat req, is my stats. may very well be possible with lower stats, i have not tried.
1: First buildphase, place down auras and beams/wall.
Place the 3 LTS, and 2 DST's west. Recommended: Upgrade the West beam 1 time, to increase range and make sure you dont take core damage
2: Place atleast 1 LTS and 1 DST covering south spawn. Continue building during wave.
I bring in T-Boost here and finish build during second combat phase.
3: Use the rest of your DU to place DST's facing the pillar/boss.
4: Stand here with tank preferably using fairy.
Last wave i have 1 App tank(90% Res), Builder apprentice, Guardian apprentice(With apprentice guardian) and Towerboost boosting DST for boss wave.
