Build requires only 2 stacks of auras, consisting of 1 strength drain and ensnare each, placed where shown on the map. Hint 1 place the DST's as shown, and then spam the rest of the 9 LTs remaining onto buff beam, then you want to place your mushie where Hint 2 is placed, nature's pylon does NOT need placing on the buff beam. but good enough to catch both stack of auras. Hint 3: i placed my minions next to those barrels or whatever, close to the stairs, wrap your minions around that stuff there. Hint 4: make sure you place minions with the 2 orcs in front, if you have over 5K THP in your minions you should be able to AFK with this build. Hint 4 is the reason as to why this build is not AFKable enough, especially after W30. ( build is MOSTLY AFKable still ).  Hint 5: place your minions in front of the spawning chest, just close to the corner, or opposite side of the chest, they are mainly there as support, feel free to move these 3 minions wherever needed. also that solo spider I placed on the stairs close to forge (I would keep that spider there imo). you will also be having 2 webbed walls: x1 2DU webwall and x1 3DU webwall. 2DU webwall can be placed as shown on the map, or closer to the crystal, its there mainly for when ogres clog up next to crystal. 3DU web wall will be a bit tricky to place since you need to cover the air pathway the ogres and mobs come so that way it covers ogres going for the crystal or tryna get up the stairs :D      Edit: I forgot to mention that you can up defenses with your upping mage from halfway down the ramp I marked with the green arrow. I use one booster summoner with a Huntress and Monk guard pets, and after 1 or 2 upping waves I switch to another booster with the same stuff. Make sure to boost auras with your pets if you missplaced or not upped enough at the beggining the pylon. Enjoy!
