Yes, new abilities will manifest. What will they be? Sorry, no spoilers! :)
ima make a guess
I'm guessing it is going to be something about his combat because he usually uses his powers to fight and we don't have an ability to buff damage
So kind of like Yuji Itadori's Divergent Fist?
Also I'm honestly hoping that if we ever fight a Human form of the Eldritch (Maybe a Clone of the MC) it's gonna act Sadistic to Another Level to make the Final attack amazingly Satisfying-
