Before wave 1  - Get two chests closest to where you spawn, and build auras and buff beam (on top of bridge)

Wave 1 - bring in TB and Guardian builder, and drop mana to Guardian who builds 12 owl nests. After building owl nests, builder runs around doing secret. TB upgrades buff beam. I aim TB towards spawn at 2

Wave 2 - Bring in upper adept and aim at spawn near 3. Around 300 mobs killed, I finish the secret if i didn't finish it with guardian first wave.

Waves until boss wave: Guardian summoner with 2 huntress guardians + TB and afk

Boss Wave: I do |DPS monk with HB Spec and eye | + |TB| +  | DPS Hermit with Eye|  + | DPS Hermit with huntress guardian|. You could do 3 hermits + TB for one more shield, do a cat instead of huntress guardian (prob works but not tested),or summ with 2 huntress guardians. The choice is up to you. I cut TB boost around 580 / 590 or so mobs and its usually up in time for boss fight.

Boss fight: Stand under bridge with all chars, TB and HB and sit afk. If you HB with your DPS Monk, you can use N on keyboard to drop half of ur mana from TB to your dps monk to keep the HB going longer.

Extra Notes:

You can remove 1 or 2 owl nests to add in a golem / pylon or golem + pylon / extra ensnare + strength if you want the extra safety. A little slower in build but a considerably safer run if your stats are lower.

I think the only hard stat requirement would be the range on monk if you're only doing 1 aura stack as it needs to cover both crystals with a fully upgraded buff beam. With a pylon the stat requirement is likely lower. Guardian /EV stats are just my stats.

I don't think this is a tower kill build, DPS chars with eyes are required I would say.

When building Wave 1, a spider may spawn close to you, just be careful to not get webbed

I do take core damage but it's usually minimal and probably just owl targetting, i've never lost a run with this build.

You have extra DU for reflects but i didnt find them necessary

My combat time varies depending on boss fight but i can consistently hit under 10 minutes total with this build (12 owls). 11 owls for me was also sub 10 minutes total, and 10 owls will likely be sub 10:30 total.
