Build phase 1: add one or two LTs if possible, if not use temporary gas on both buff beams

Build phase 2 Just use up the rest of the DU on LTs 

Boss fight: Use twr booster, guardian summ and your app builder to max out the dps on the LTs. 

Hint 1: build LTs in the corner and use the big walls as shield from cupid arrows

Hint 2: Use minions here if your stats are not high enough. Those minions should make it doable with much lower stats :)

Hint 3: Use a dps monk here to kill the squires faster 

Washboard was kind enough to record a run with this build, so a big thank you goes to him :D
