Finally made it to Camp.2 lvl 60 Boss, but... cant beat it, as expected. Anyone there? Any tips? Everything seems so ridiculously OP at that lvl

The only idea i came with was to lure boss and fight him at left side without bothering to go past the archers. The question is, is it even possible to out-dps the healers and kill the boss in time. Also, unlike lvl 60 easy, he is hitting for like 800k a hit which isnt helping at all. Trying to heal doesnt seem viable at all. Will try Bilie/Zera/Heat/Daphne combo to try freeze/kill him but i suspect i wont have enough dps. Probably another fire dps maiden instead of Daphne would work better, but i dont have unfortunately
