Attack Rating

From Diablo Wiki

Attack Rating is diplayed on the Character Screen. It shows the percentage chance that you will hit the targeted monster, as well as the chance of the targeted monster hitting you. If your Attack Rating is too low, you will notice that your attacks often miss. The chance to hit increases if you are at a higher character level than the monster you're attacking. Your Attack Rating can be improved by increasing your Dexterity, and by equipping magic items that specifically increase your Attack Rating.
