I see I see. Hrm. Well, alright then, seems like you are right. And yes, you need to find Rare and Legend items out in the wild (though for orbs, muscles and treasures, there is the hospital prize exploit, if you have the patience for it.)

If there was a formula (like, a Rare always has X stats higher than a Common, Legend has Y stats higher, etc) that would help us simplify things, but for now, just report what you find.
