1. 

- 3x Lightning Tower

 - x (rest of DU) Golem

If your LT's arent killing fast enough exchange a golem for extra LT's

2.

Use traps here, or better yet place a summoner DPS or Tank with Damage/Heal pet to kill any stray mobs

3. 

This beam should be able to intercept both aura's (With around 5k Aura Range)

If it does not then you could use a monk guardian to boost them into it or just use seperate buff beams on each aura

4. 

This is where you place your boost summs and/or Tower Booster; behind the LT in the tunnel area

The Strat is to let the Queen Wasp fly into the golems.... and get beamed by rocks. With Tower Boost it should die very fast

If your golems aren't tanky enough I recommend placing summoner orcs in a circle around them with a mage infront of the golem.
