Mirror Image Random Hit

Rules Questions

I have a question regarding the spell mirror image. I've searched the forums for this answer, and found about a bazillion threads regarding mirror image, but they all seem to focus on either targeting the images specifically or finding a way to circumvent the images and hitting the caster directly.
My question however involves what is stated in the spell description itself. "If the attack is a hit, roll randomly to see whether the selected target is real or a figment. If it is a figment, the figment is destroyed."
What is this random roll? Do i roll vs AC, a percentage dice, what? If its AC, whose AC; if its percentage what is that number and why? or is it just a d6, assign the real caster a number and if you roll that number you hit him? Please help. Thanks.

I have always treated it as a percentage roll. For example. If the wizard has 5 images (for a total of 6 options), I would just roll a 1d6 and say that on a 1, it hits the wizards, 5-6 hits an image and destroys it.

If there are 5 total for example, you could still roll 1d6 and just reroll 6's.

If the roll is high enough to hit the caster assign the caster a number and roll a die based on the number of images plus the caster. EX: a Wizard has six images plus himself for a total of seven targets, assign the wizard #1 and roll a eight-sided die, ignoring eight. If the number rolled is a one it hits the caster, if not it hits one of the images.

Now my question is, what if the roll is high enough to hit an images AC but not the casters?

They all have the same AC. First you roll to see if it is a hit at all, using the wizard's AC. If it hits, then you roll to see if the target was a figment or the real wizard.

Wouldn't the images AC = caster's?

In pathfinder the images don't have an AC. If you roll high enough to hit the target AC you roll randomly to determine if it was the target or an image. If you miss the targets AC by 5 or less, you destroy an image.

Yeah, that was my bad. the AC difference was a hold over from 3.5 still stuck in my head.

Happler and I do this exactly the same way... Add whatever number of images + the actual caster and roll a die closest to that and if you roll 1 it hits the caster, anything else is an image.

I do the same thing, but have the player call out a number as the die in the air. If they get it right, then the wizard is hit. Gives them a bit more of a feeling of agency.
