originally by dad bod, i made small adjustments though.
hint 1 requires stacking
before starting make sure to upgrade all darkness traps to have atleast 80 health (do not max them out) and make sure to max out the buff beams
start on wave 21 (or 22) with jester on main and 2 summoner hunt+monk guardian pets (make sure to have some health and res on them)
stand on your LTs and shoot towards hint 5, aiming slightly right and above the stairs where mobs go, as this is the best way to get mana. starting on round 21 ensures you upgrade all LTs and golem to three stars. after that from wave 22 onwards you should be on 2 summoner swith hunt+monk guardian pets. (if you cant max just the LTs and golem in 1 round, try starting earlier to make sure you can max them)
thats the whole build
NOTE: if you have lower health auras (like myself) you have to be pretty attentive and flash heal when they start getting low, also when the round ends, you should go around opening chests and you must repair the darkness traps, so that they dont die during the wave.
