I won't lie, this map is annoying to farm after the scimitar nerf. I took Dubu's old build and modified it to account for the fact that double boost might not always be up. For auras and traps, place them as close as possible to core. For traps, remove your gears before placing traps, so you can place them closer to the core, then re-equip gear. The low HP on gas traps won't matter since you'll upgrade them on wave 1. This is not the fastest build. It aims to take a reasonable amount of time while being safe, especially for people that don't have extremely high stats.

On the first wave you do have enough mana and time to build all except the spider queens. I start off on monk and place all auras and grab all chests. I then usually usually switch to traps, then to EV, and I finish on Apprentice for towers. 

Spider Queens are optional. They do help if you're solo. If both your boosts are down, these little spider queens can save you from ogres getting to towers. In a group there's no need for spider queens since other people can help boost and maintain 100% double bosot (2 monks and 2 initiates to boost). 

For the first wave you can Jester solo, or Jester with tower boost monk. During the first wave you should have time to max all buff beams except east, and you should have time to upgrade to 1 star auras north and south. Max upgrading would be ideal, but not necessary on the first wave. After the first wave, you'll have to switch out your Jester for your Initiate since ogres and cyclopes will start spawning and you'll need double boost. 

The stats I listed are the stats I think are required for this, but might go lower, I have no idea. First time I cleared it, I had similar stats, my apprentice had 7700 power though. 

If you have 2 tower boost monks and 2 initiate boosts

In this scenario you can keep double boost 100% of the time by alternating monks. In that case, you can get rid of everything on the east core, all auras and buff and trap. Instead, build the middle stack behind the wall close to the bridge and add an electric aura. The extra DU can go into more towers. The initiate boost will make it so the auras will kill mobs east.
