I've done some Mind-stat-testing myself, and my result is that 1 Point of Mind equals around 1.5 healpoints on Physick. Thus I'm considering of using the Int-Hero-Ring (my current ring is still the DL ring so i'd be losing 9mind and some piety). In other words, if my assumption is correct i'd lose 13.5 healpoints on physick and about 70 mana (or something like that), while gaining 13 (or was it 16?) crit.

On a side note: Congrats
