Hint 1: Stack Lightning towers. Look up a guide if you're unsure as to how you do it. There is no buff beam for the towers; you'll have your familiars boosting them instead. (Hint 3)

Hint 2: Archer Walls are on buff beams and meant to stop ogres; mages/spiders are far enough away to avoid interruption from ogre swings while still close enough to support the archer walls. You are free to use the extra minion units on whatever you desire.

Hint 3: Run 3 other controllers: 2 summoners with App/Hunt/Monk guardians along with an Imp and 1 tower booster monk; you will play as a jester with a genie and managun. Make sure your summoners have adequate armor with resistances/hero health.

Hint 4: Upgrade everything except for the darkness trap. It exists to nullify ogres elemental affinity before they reach the strength drain aura and allow lightning towers to grab their attention from the crystal.

Playthrough: At the start upgrade the outside crystals to max then go to the inside and upgrade; everything should be upgraded by wave 5. Have your Summoners with guardians boost your lightning towers and have your Monk's tower boost activated when possible using your Jester to feed him mana. As your Jester, use your wheel to roll Heal to restore outside defenses and Kill% to alleviate pressure from ogres. This build starts to bend around waves 12 - 13 when ogres hit 200m hp. The East Crystal might rarely be targetted by ogres who fail to agro to lightning towers; if the darkness trap doesn't work then remove it and use an EV wall by the crystal to prevent ogres from hitting it.
