and the Inferno Hammer is:
5-10 FD <-- wait...
10 MSR <-- that's a new one!

Not knowing what these numbers mean doesn't impede my game play much- now that I've finally got some experience points to put into Dexterity and melee I'm not falling over as much
, it would be nice to experiment to see if they actually mean anything...
