If the difference in strength is 5k or more, the damage to the enemy will be 0 (weak) and the damage multiplier + constant crit will not help to pass the stage.
My power is 10k, and the recommended power of the stage is 15k, my damage at a multiplier of 100x does not pass. We need to do something about it, because as I said earlier, this mod loses its relevance at high stages. It is necessary to pump the heroes necessarily.
