Soon as we held the stones we'd know something had changed about us, the next is to accept that what the woman who released us said about the stones abilities as true. Accepting that means we now have to use our minds to focus them which means an exercise of will and confidence; as an acrobat Laura has to trust herself and others, she must focus on the risky signature stunts. She only knows a bit about Alchemy and Philosopher Stones but what she knows is it is the practice of the Transformative allowing the alteration of one element to another and or the reshaping of the object that is the focus of Alchemy....She has a Pottermore account lol
