My velocity is not working whatsoever, even if I put it on 0% and 100% chance its almost as if I take more knockback than vanilla minecraft. Any reason as to why?
Keep it at 100% chance. Do 90/100/100 for velo and it will have a small change. It is usually not noticeable. Also toggle blatant mode. It makes velo more smooth in modes like boxing and sumo.
