still fine tuning, but this build works well
3x hunt/app guardians works best, one on each stack
wave 22 build - upgrade buff beams at top and bottom most core to 3 star
fully upgrade middle, then upgrade sides. should get all the upgrading done by the end of the first wave.
~36 minute combat, stuck mob issues near top-most core for the furthest spawn, but djinns come up behind your stack and can cause the beam to die unless you have 4x wisps, might be able to adjust the build a bit to make it more centered but ymmv
