On paper it seems useful to create 3 illusions of yourself and gain +9 AC. But it only takes less than a turn (3 attacks) to remove all 3 illusions. When you get hit, it's bad; and when you don't get hit, it's STILL BAD, because it removes one illusion and takes away 3 AC. A spell should at least benefits you for at least one turn. And this one is good for possibly less than 1 turn -- all 9 AC gone in three quarter of a turn! When an enemy casts Mirror Image, I LOVE IT, because it's an easy spell to beat as I described above. If I cast it, is there any scenario that would exploit more benefits out of it?
