Under 1:30 minute initial build time. Total run time is under 10:30. Build auras first starting with the bottom middle aura stack and then go counterclockwise in building auras and collecting chests. You don't have to be too accurate with the aura stacks as the buff beams can be adjusted to make up for any larger than 4du buff beam discrepancies with the extra DU leftover.

For the first combat wave, start with your upper and just go around upping. It will take you until at least the second combat wave to completely upgrade everything. Afterwards, take out your TB and just boost all the Electric auras from the middle of the map. Or just huntress guardian and AFK. Or just don't bother and go ahead and AFK. Whatever works.

With my stats, you could go without upgrading or repairing anything other than maxing the buff beams, except for the last wave - you'll need to repair the west and northeast Strength Drain auras.

Tip

• For the last wave, pull out all of the same characters that use only 1 weapon type to maximize end of map rewards armor drop amounts. In this case, I pull out all monks, with one being the builder monk. Similar end of map rolling logic from Lab Assault appears to apply here from the small testing I did (which the logic probably applies to all maps). This map dropped some ult armor for me, so it will eventually drop a ++ sometime hopefully. For the quality modifier of the armor drops in this game mode, I have no idea.
