All defences are Fused with the exception off Reflect Field and OC Beam 2-4 Players
1 Tank, 1-3 Tower Boosters

Electric, Ensnare, Dst's & Healing Fused Solo

Hint 1: Have a squire with striking range gem to bait ogre's away from core. (2-4 Player's)
Solo i would recommend having a monk on militia set that can put down fused healing and stand there with range gem.

Hint 2: Place the inferno (Huntress) Trap's so they will hit OC beam with the Gem. 
I spread out the aura's so they are easyier to see. I like to stack them all on top.

Hint 3: I place those reflects to stop ogre projectile's from blowing up before the tower's (Kobolts)
Strength Drain Aura 2-4 Players, Solo i cut out the Strength Drain from the build and make art with Reflect Field's

Hint 4: you can swap out aura's and traps if your stat is not high enough for this build. 
etc Gas Trap, Darkness, Electric, Ensnare.
Just remember to have 4 in the stack that the Gem will boost

Hint 5: these are the 2 angle's i have my DST's set to.

The stats listed are just my stats idk what the thresshold is for completing the build
