One of my players wants to play a charector who wants to be able to make things ,including himself, grow by touching them with one hand and and shrink by touching them with the other. The effect on himself would only effect a body part. For example he could touch one arm,leg or whatever and it would grow muscular and large, be super strong and the other hand would return it to normal. Im not sure how to handle partial growth, or should I be thinking str for arms, running and superleap for the legs. And the effect on other items get even more confusing. Any suggestions?
