Area of Effect vs. Mirror Image

[Kristoffer O]

It is probably the Mirror Image that is borked. There is another bug on that spell. It doesn't prevent fatigue loss from life drain attacks IIRC.

To hit a mirrored unit for sure you need a 100% precision, 1 target spell (like Soul Slay, or Incinerate).

I'd agree AoE Spells should hit the unit ignoring the mirrors, as all the area is struck, so both the real unit and the mirrors.

[Ironhawk]

Another interesting thing: if I recall correctly, none of the mirror images were destroyed either. That was the third option that I was considering - that perhaps the ball spell hits all in the square, but has a chance of hitting a mirror image instead of the real mage (like a normal attack/missle/bolt spell would)

So... does this mean that Mirror Image makes you immune to area of effect spells?? Does anyone have solid experience which counters this?
