the mystery delay is the only thing that annoys me about this game tho

Ok, i understood what happened - i think - you just had used kushina mystery in that round, somehow you endured 6 hits with her and the cd got reset so you clicked or the auto did it for you on her mystery again, but since the mystery couldn't go off again in that round was delayed to the following round. In that case can be interrupted even by slower mysteries. Every dance of impetus user know about this.

naa bro it was the 1st turn, he did shisui combo on my kushina, after that i activated her, he activated his lightning and stopped mejust like that...i never activate the kushina mystery 2 times in the same round cause there's always that risk of getting stopped
