Lately i find dex a more and more interesting stat. havent yet put any points in it and i doubt i will, but dodging attacks is great
my axe gives me 19dex, another 25 comes from my rings (when using the dex rings). throwing up an evasion scroll makes my fighter avoid like 1/4-1/5 off all hits from yellow named monster (usually. some mobs like procks seem to have a very high accuracy).
havent tested it much yet, but my first impression was, dex might be a better defensive stat then end o_O (for someone who is not using shields).
and about the accuracy, accuracy=damage when fighting higher level monster
