About the Philosopher's Stone....unlike a lot of the stuff on this show, this was a real myth believed by a lot of people in early AD. However, its use here is off-base anyway. What the Philosopher's Stone was really supposed to do was change any metal into pure gold. That's all it was supposed to do if it existed...it didn't give you "all the powers of the cosss-moooss" like Mozenrath said it would a billion times. Hmm....on another note, it's awfully convenient that it self-destructed for no reason....lazy writers.
