The 6 LT's should be in the middle of the buff beam with the ensnare aura right in front of them on the south side. Use a summoner boost with expansive and speedy poly on the ensnare so the ensare and LT's are buffed. The DST should be on one side of the LT's and the other side should have the mortars and harpoons. The two mortars facing the upper crystals and the harpoons should be aimed so the edge of their line of sight can see where Hint 2 is.

For waves 32-34 use monk TB and the summoner boost stated above. Towers do take a decent amount of damage sometimes early wave so higher TB helps heal and better tower HP also helps but was possible with 3300 app tower hp. Wave 35 use monk and initiate TB and a second summoner boost with speedy and destruction poly's on the mortar/harpoon stack.
