Piercing cold mutation

Hey guys, just a quick question i made a kinda hybrid build between sword attacks and signs, then delved into this cool mutation stuff, and saw a video on how piercing cold mutation could freeze enemies mid-attack an such, so i decided to try it but it didn't freeze neither monsters nor bandits, it just killed them instantly and ripped bandits apart, and that's too op in my opinion, i play on death march on with up-scaling and level 46 in my first play-through, so can anyone suggest how to get the desired outcome of just freezing enemies or could share a build or a save game, that have these effects.
much appreciated guys.

Did you read the ability description?
It's supposed to freeze/slow enemies, but it's also Aaard, so it has a chance to knock them back.
What it happens there is that when you "roll" both a freeze and a knockback in the same attack you trigger an instant kill. That's pretty much it.

If you're playing on PC, you can request a mod in this forum and perhaps someone would make it. I have very little experience in modding, but I imagine it shouldn't be too hard.

Lowering your sign intensity would give you the slow or immobilized effect without getting the knockback for an instant kill but that would weaken your other signs. A mod to get rid of aards knockdown effect would probably be what you'd want.

in my new game plus end game Geralt (enemies ranged from level 62-78, I could only freeze them or make them slower, rarely once or twice killed something with it. In my end game Geralt it was instakilling a lot of enemies ( they were ranged from level 32- 48 Both saves death march
