Only a percentage of whatever is inflicted on the clone gets to MC right? I mean he used those broken potions and shards all the time on the clones and didn't get monster buffed skills

No the shards aren't safe for humans because of basically monsterfication of the person that's why he gave a bunch to his clones and they got red hulkfied
But even so it wasn't a new skill
Whatever mr mad scientist did actually broke the rule enough that if affected the main body to the point of he just manifested a new skill
It's this the Ick I've heard people talking about he is giving it off
