Blindsence and Mirror Image?

[Perun]

A question to all the DMs out there.

If a creature with blindsence attacked a character with the Mirror image spell active, what would happen? Would blindsence ignore the images created by the spell? And what if the creature with blindsence also had Blind Fight feat?

Thanks in advance.

Regards.

Reading over the SRD, there's no mention that Blindsight or Blindsense let you ignore figments or any other illusions (with the exception of illusions like Displacement, Blur, and Invisibility that provide concealment). Presumably the illusions simulate sound and scent, so they appear just as real to blindsenses as they do to visual senses.

Mirror Image says it won't work against creatures without sight, I'd say that's pretty damning evidence against it providing signifigant non-visual output.

I think they could use blindsense to find the real image then just use vision to track that image until the mage moved again. MI isn't the best definated spell.

Tremorsense should work and BlindSIGHT definately.

I wouldn't allow Blindsense to penetrate Mirror Images for the sole reason that it lets you pinpoint, but not see invisible creatures. For example, if an invisible person were in front of you, a Dragon could tell what square he was in, but he'd still have the miss chance if he tried to attack his foe, because he still can't see his target- just sense which square he's in. Since Mirror Image says nothing about them taking up more than one square, knowing what square your target's in doesn't help you if there's five other him's in that same square.

Excellent points. However, as that is the case, I would allow the attacker with Blindsense to close his eyes (I'm assuming he has normal vision). He'd ignore the Mirror Images, but treat the defender as invisible. Being able to sense which square the defender is in, he could attack him each round, but with a miss chance. Then his Blind-Fight feat kicks in, and he gets one re-roll on any misses caused by the invisible state.

It says they must stay within 5 feet of the caster or at least one other image.

It's theoretically possible for every image to occupy its own square in a line 45 feet long, and still fulfil that requirement. (Unlikely, but possible.)

The FAQ suggests that for simplicity, one can treat them all as occupying the caster's square, but then the 88% miss chance can be turned into a 50% miss chance by anyone - you know which square the caster is in, so you close your eyes, attack his square, and open your eyes again.

By anyone who has knowledge about that spell (Spellcraft) or is metagaming.

Blindsense does not help. It would only allow to pinpoint the caster, but you can do that anyways, since you do not have to guess a square or anything even normally. Relying on Blindsense only and not normal sight would give the standard 50% miss chance (or 25% with Blind-fight). Using Blindsense combined with normal sight, would do nothing at all. Blindsense is not accurate enough to distinguish the caster from the images.

Blindsight, however, completely foils the spell.

Spellcraft isn't required - just that someone's said to you "Your eyes can deceive you; don't trust them" with regards to MI.

It would only allow to pinpoint the caster, but you can do that anyways...

Only if all images share the caster's square. Which the 5' rule doesn't require them to do.
