You can do this with or without a huntress DPS. Having a huntress DPS in will speed up the boss fight, typically about 30 seconds to a minute faster.

I haven't tested stats lower than what is listed, but it might still work.

First Build Phase

• Build everything, but the Forest Golem and Hint 4's Cloud Towers. You don't need the reflect beam protecting the "middle" crystal if your stats are high enough.

During Waves

• Fully up the buff beams first, starting with the north buff beam so that the aura stack is able to protect the two northern crystals. After everything is upgraded, pull out your Tower Booster and boost the north towers.
• Boost in front of the Forest Golem at Hint 3 pointing towards Hint 5. This will help prevent mobs from getting stuck and also attract more enemies to the north crystal rather than the "middle" crystal.

Second Build Phase

• Build the rest of the structures.

Last Wave

• If you are using a huntress DPS, switch to your huntress and then spawn in 2 summoners (one with double huntress guardian pets and the other with double apprentice guardian pet) and your Tower Booster with some Hero Boost stats.
• If you don't use a DPS, then stay on your Tower Booster and spawn in the 2 summoners mentioned above along with your builder Warden.

1. Move all characters but your Tower Booster to the safety of the reflect beams at Hint 2 and 4. Have your Summoners Phase Shift into the towers as space will be tight since all 4 characters will be there eventually.
2. When there are a few enemies left, turn off the Tower Boost and move the Tower Booster to where the rest of your characters are at.
3. Tower Boost to kill the bosses. Hero Boost as well if you are using your DPS actively. Warden Boost if you can.
   • The northeast cupid will be attracted to attacking the north towers, but they will be protected if the reflect beams are placed correctly.
     • If you have your DPS in, you can shoot at it to change it to go towards the south towers instead.
     • If you don't have your DPS in, you'll just have to wait until the northeast cupid wanders into the line of fire.
   • If you leave the reflect beams and a cupid decides to shoot at you, be careful about going back behind the reflect beams as any dodged/late cupid arrows can duck under and curve back up, hitting the towers. So leaving the reflect beams is risky.

Hint 1

• The Cloud Towers are not built as a stack. They are built against the door "frames", pointed in the opposite direction. In other words, the Cloud Tower built against the east part of the door frame will point west, and the Cloud Tower built against the west part of the door frame will point east. In other-other words, the Cloud Towers will be staring into each other's eyes very lovingly.
• The Reflect Beams need to be built right up against the outer wall and door frames to protect the towers from the northwestern cupid boss.

Hint 2 & 4

• Make sure the Reflect Beams are making a small enough angle so that the towers and characters are protected from the southwest cupid.
• Make sure the Wisp Towers are forward enough so that Cloud Towers can fit behind them.
• You'll have to jump on the mana chest during the second build phase in order to be able to build the Cloud Towers.

Hint 3

• The Forest Golem is built at the end of the buff beam so that it helps attracts more enemies into the north "room" while protecting the towers and also taking the webbing from the spider.
