So my champion have double dicks and when I decided to TF them it's only affected one of them no matter what I do, is there a way to choose which one I transform or if I can can transform both of them or not ?
If you want both of them to be the same type just take another shot of the same TF again. Otherwise if you want one to be x and another to be y you'll have to rngesus and hope it targets the one you want.
