a) Utterly destroy Act 1 and die on the rarest of occasions, killing stuff rapidly while knowing where a lot of elite/champions are and getting bags full of i55-i62 with the occasional i63 rares. 2% for i63. (Then go to Whimyshire for fun at the end! -i63 8%)
b) Do ok in Act 2 but still die on occasion, killing stuff at a moderate pace but not knowing where elites/champions spawn too well. 4% for i63.
c) Get owned in Act 3 but still be able to take down elites/champions slowly. 8% for i63.
d) See c for Act 4.
