you may wish to read the thread ' SPOILER: Alchemy - create/combine potions ' as it has a somewhat similar discussion involving stats.

speed.
this will help your attack speed. please be aware that the sword itself will often have a minus to it's attack speed rating. i believe you're far better off (at least for the first couple acts 'til speed is built up) giving up a little bit in damage to gain a flat speed (no minus), or even better, a plus speed.
also recognize that many items you could be wearing actually detract from your speed rating.
