At '2': Summoner with Djinnlet (ranged gather mana) and Imp (auto repair aura). The summoner will be safe on this side of the wall and any chip dmg will be healed by the aura.
Place Monk/Hunt, Monk/Hunt, App/App Summoner by towers. If your Aura HP is too low you might need to heal the auras at '3', I have no issue IIRC at 3k aura HP. The auto repair summoner should hit the left and middle aura stacks.
'4' I am not 100% sure these are needed, no mobs seem to come up this ramp but I always put 2 archers here and 2 mages behind. Make sure your auras at the center crystal reach the spawn below or these summons will die.
Round 1, place serpent staff upgrade aura adept on towers and aim at '5'. You might want to beef up the towers but not all the way to 3 star, before getting them to 3 star you might need to upgrade the summons a few times.
I don't know the exact archer amounts, just place them shoulder to shoulder and 2 mages behind each row. You should have be able to block off all sections with 1 archer to spare. I usually put it near the row at '5' just to make sure nothing slips past.
The Gas Traps are not required but can be useful if you are having issues with the suicide bombers killing minions.
Stack all auras on top of each other, they are just split like that so you can see it's a full 3 stack.
