Decaying Winter Sledge Queen Oneshot Paradox

One thing i probably did get right in my previous Sledge Queen oneshot attempt is that there is an anti cheat to prevent you from Actually oneshotting her. Which is pretty stupid considering all the powerful hacks there are for this game. I did 1350 damage with one hit and she didn&die, and no it didn&just not count the damage because she died instantly from the next hit. Why did i waste my time doing this...
