what about the game crash? the crash every time i use this method
Well, I don't really like this method, but if you're really annoyed by those solo raid boss, then go ahead and use it
Actually you don't have to multiply the damage till you one hit kill the boss, just make sure you deal a lot of damage (killing is better)
For example:
When one of your hero die, set the damage multiplier to 2000x or 3000x, then pummel that boss
if your game crash with that much amount of damage, then lower the multiplier to 1500x or 1000x, no matter the boss dead or not the damage still applied
my record is 8000x without crash
