Why are you healing at the evil healer and not the good or neutral?
Why are you not using preps that you can buy very cheaply (protection, stoneskin)
Why are you not using teleportation potions that you can buy very cheaply (this is a big one. Every time you flee, I guarantee you half the people reading this board are thinking "QUAFF, QUAFF, QUAFF" .. and you never do. Ever.) :(

I mean, if you just did these things, especially the last one, it would be make happy :)
