build works with lower, i do recommend a minimum 6k range aurus though, i run 2summoners with 2x huntress 2x monk guardians and boost monk, i dont bother goldening but if your higher stats this deals with goldens no issues, you could do 1x dst instead of golem but i like golems :D
yes i stack all the dps towers in 1 spot, the pylon should reach the str drain on other side, if your pylon range or aura too short just move the str drain till it gets boosted or leave unboosted, doesnt really make a difference if your not goldening enemies anyways.
