How to Win Crash Impacts

This can feel like one of Impacts you’ll see the least, since it’s not tied to any offensive actions. Both characters performing a Step at the same time will trigger a Crash Impact. They’ll both punch each other’s fists if the timing is right.
You and your opponent will each take on a random role as a defender or attacker. One of two button prompts will show up in the middle of the screen. Whoever presses their prompt first will win an exchange. Up to three can take place, with the best of two winning the overall Crash Impact and punching the loser away.
Pressing the boost button is supposed to help with your timing. To be completely honest though, I’ve never noticed any difference. I’ve seen some claim that it helps with accuracy, but no aspect of the QTE seems to support that idea. The game itself simply says you need to press the prompts first. I’d only recommend using the boost if you’re constantly on the losing end with this minigame.
