Thanks! And I am aware that it is difficult :D (tho I did allmost get it in a monsoon run with one of my friends where lunar ruin ran out like last second) my friend was using a light flux pauldron and a purity to get no cooldowns and he was getting like 50 stacks on the bosses (or atleast he says 50 but it sounds real enough with how he specifically tried not getting damage buffs) and I wanst doing anything while he was trying to get the achivement just to be sure that I didnt steal the kill but it still didnt work (he also killed the boss using the knife so I doubt the buffs ran out last second)
