The AC for each image tends to be 10 + Dex which tends to fall in the 10 to 14 AC range (for the most part). And, there are from two to eight images (two to five images at low level).At low level, this means that most opponents will be able to minimally dismiss an image the majority of the time, even if the attack would have normally missed the caster.Let's take a fairly common example.Third level Wizard with a Dex of 16 and a Mage Armor (or Shield using 3.5 rules) spell up in addition to 4 images from the Mirror Image spell. He has an AC of 17.Opponent with a +4 to hit (which is fairly low for an opponent of a third level wizard), one attack per round.Round one: 48% chance to take out an image, 8% chance to hit Wizard, 44% chance of missing both.This is about the same as if Mirror Image gave the Wizard a +6 AC.Round X (once one image is destroyed): 45% chance to take out an image, 10% chance to hit Wizard, 45% chance of missing both.This is exactly the same as if Mirror Image gave the Wizard a +6 AC.Round Y (once two images are destroyed): 40% chance to take out an image, 13% chance to hit Wizard, 47% chance of missing both.This is about the same as if Mirror Image gave the Wizard a +5 AC.Round Z (once three images are destroyed): 30% chance to take out an image, 20% chance to hit Wizard, 50% chance of missing both.This is exactly the same as if Mirror Image gave the Wizard a +4 AC.As can be seen, this is not (at lower levels) that much more overwhelming than the caster casting a Mage Armor or Shield spell (in 3.5, in 3E, a Shield spell would often be a lot more useful than Mirror Image at lower levels).For a few rounds, the spell is more potent than many other defensive spells, but it quickly starts lowering.This example also assumed that 2 defensive spells were up (e.g. Mirror Image and Mage Armor).At higher level, the spell caster gets more images. However, his attackers often get more attacks per round. So, the utility of Mirror Image at higher level starts decreasing. For example, most high level archers can take a Mirror Image spell out completely within 3 rounds (and probably hit the spell caster a few times in the process).And, there are even low level ways to minimize this like BlindFighting and closing your eyes. In the example above, that would relegate the Mirror Image to a +2 AC bonus for the duration of the spell. Even without blindfighting, closing your eyes lowers the AC adjustment of the example above to +4 (just like a 3.5 Shield spell or a Mage Armor spell).</blockquote>
