Build Description
1. Tower boost on bridge can boost all the lightning towers.
2. Minions placements. But do you really need them?
3. Should be obvious, but all your auras should be buffed with just the two buff beams.
4. The hidden buttons for the secret are in those locations
5. After hitting the buttons, it's time to dance to open the door to the left of the DDR machine~
I use this same build on nightmare hardcore with 2k tower stats.
