Fist now: weak as heck. (I say this because monsters with a brain can just... walk backwards a bit... I'm a MX main and anyone who tries this on me just gets destroyed. Doesn't help that its loud.)
If I happen to have the gauntlet, and my jogo avatar on, thanks to this video I will always yell in chat and vc KAKUSEN or BLACK FLASH to the monster every single time and it's worth it always
