Blue arrows are for mortars / Yellow arrows for rocket launchers.
Start wave 32, build everything and up buff beams. I use EV upper + App upper. App upper focus on upgrading Hint 3, while EV upper focus on upgrading Hint 1. On hint 1, place the stack on top of the stone pilar.
I spam wheel triple swords on CD.
For last wave, use EV to spam wheel, guardian summ (app + hunt) on Hint 3, and EV + Squire builder.
