I started off with KoD's genie farm build, which works great for the waves genies are on (wave 23-25), but I found I liked this map as an armor farm (with TB monk present it still drops a surprisingly high number of armors vs weapons) and wanted to keep going to 35 consistently, so made adjustments.  

Party Members include: Tower Boost Monk and 3 Summoners with 2 each every relevant guardian type (Huntress, Monk, Apprentice)

2 sets of auras to cover as much of the map as we can in slow/weak.

Hint 1: Mushroom stacked with 5 Seed Bomb Towers: 2 Seed Bomb towers facing east conrols the entire side--3 Seed Bomb towers with good clean angles facing Southwest

Hint 2: Stack of 5 LTs

Hint 3: 2 Golems for rock throwing and aggro.
