Stat requirement should be around 5k, and less if you wheel alot.
Hint 1: Put every character when fighting the boss colse to the Physical beam(It blocks the cupid arrows)
Hint 2: Dst facing in these directions, 6 towards the boss spawn (stacked on the 4 du buff)
Hint 3: I use 6 Archers on each Buff beam and yes they are stacked to fit them on the buff. Just add more minions or mages if you are having trouble
Wheeling Damage all on jester is really nice for this map so might even wanna add extra characters that can wheel.
Boss will only be doing damage to that physical beam so make sure to heal it mid fight and this should work just fine :D gl & hf
Update: For boss you want to join in with a guardian summoner, tower boost monk and that should kill the boss all on its own. 1 dps character is nice to have just in case(never had any problems letting my dst's kill the boss)
For update 6: removed dst facing wyverns getting stuck inside the wall on shout core, that dst is now facing towards the boss instead for more dps.
