Blur + Displacement + Mirror Image?

[Lamoni]

Just confused as to how to handle these when used in conjunction with each other. Seperately, they make perfect sense. Let me quote the SRD so you don't have to bother looking up the exact wording...

Blur
The subject’s outline appears blurred, shifting and wavering. This distortion grants the subject concealment (20% miss chance).
A see invisibility spell does not counteract the blur effect, but a true seeing spell does.
Opponents that cannot see the subject ignore the spell’s effect (though fighting an unseen opponent carries penalties of its own).

Displacement
The subject of this spell appears to be about 2 feet away from its true location. The creature benefits from a 50% miss chance as if it had total concealment. However, unlike actual total concealment, displacement does not prevent enemies from targeting the creature normally. True seeing reveals its true location.

Mirror Image
Several illusory duplicates of you pop into being, making it difficult for enemies to know which target to attack. The figments stay near you and disappear when struck.
Mirror image creates 1d4 images plus one image per three caster levels (maximum eight images total). These figments separate from you and remain in a cluster, each within 5 feet of at least one other figment or you. You can move into and through a mirror image. When you and the mirror image separate, observers can’t use vision or hearing to tell which one is you and which the image. The figments may also move through each other. The figments mimic your actions, pretending to cast spells when you cast a spell, drink potions when you drink a potion, levitate when you levitate, and so on.
Enemies attempting to attack you or cast spells at you must select from among indistinguishable targets. Generally, roll randomly to see whether the selected target is real or a figment. Any successful attack against an image destroys it. An image’s AC is 10 + your size modifier + your Dex modifier. Figments seem to react normally to area spells (such as looking like they’re burned or dead after being hit by a fireball).
While moving, you can merge with and split off from figments so that enemies who have learned which image is real are again confounded.
An attacker must be able to see the images to be fooled. If you are invisible or an attacker shuts his or her eyes, the spell has no effect. (Being unable to see carries the same penalties as being blinded.)

Now, the questions... How do you handle Blur + Displacement? Displacement + Mirror Image? Blur + Mirror Image? All 3 together?
Here are my thoughts... but they are only guesses. Please tell me whether I am right or wrong.

Blur + Displacement: Your blurred image becomes displaced. Therefore, they have a 50% chance of hitting the displaced image... but since you can't have more than total concealment, you ignore the 20% miss chance from blur.
Displacement + Mirror Image: Each mirror image is displaced so in order for an attack to dispel an image, it would have to also succeed on the 50% roll to see if the attack hit.
Blur + Mirror Image: Each mirror image is also blurred and has a 20% miss chance (preventing the attack from dispelling the image)
All 3 together: Treat as Displacement + Mirror Image and ignore Blur since you can't have more than a 50% miss chance.

Thanks for any input.

I'd say you've got it about spot-on. That's how I run mine, although really, Displacement shouldn't displace the images.

Displacement would only affect the main caster, since *not* having it affect the Mirror Images wouldn't necessarily ruin the Mirror Image spell, or make them look different. However, this isn't too overly powerful a combo for a wizard, and I wouldn't think it's too much to use a more generous interperetation.

My .02 (for the moment, naturally)

That's how I run it (though the 3e MI is really whacked; I just leave all the images in the caster's square).

Displacement don't interact with Mirror Image at all, Blur will give the miss chance to the images as well.

If an Image gets hit it goes away.

Making the image blurry messes up your ability to hit it. Moving the image to the side (Displacement) just moves the image and doesn't impart a miss chance becaue the image reall is there.

 

[Thanee]

Yeah, I don't think displacement has any effect on the images.

I'd probably do it this way:

Roll what you hit as normal; if you hit the caster, roll 50% miss chance, if you hit an image, roll 20% miss chance.

For what it's worth, the 3.5 FAQ has this to say:

The mirror image spell description says the images have
an Armor Class of 10 + size modifier + Dexterity modifier.
Is it possible to improve this with spells the spellcaster casts
on herself, such as shield or mage armor? If so, why doesn’t
the spell description say the images have the caster’s Armor
Class? What happens if the caster has cover from her
surroundings? Will cover improve the images’ ACs? What
about concealment? Will fog or foliage produce a miss
chance for a foe that aims an attack at an image? What
about magical concealment, such as a blur or displacement
spell?
The images from a mirror image spell don’t use the caster’s
Armor Class. Use the formula in the spell description to
calculate each image’s Armor Class (10 + caster’s size modifier
+ caster’s Dexterity modifier). Use the caster’s current
Dexterity modifier for each image’s Armor Class, no matter
how the caster happened to get that modifier. Any Armor Class
improvements the caster might have from equipment she
carries or wears, or from magic operating on her person, don’t
apply to the images. For example, a Medium user with a
Dexterity score of 16, a shield spell, and a suit of +2 leather
armor has an Armor Class of 21 (10 +4 shield, +4 armor, and
+3 Dexterity), but her images have an Armor Class of 13 (10
+3 Dexterity).
It’s easiest to assume the images share the user’s location
on the battlefield, and gain any cover bonuses that might apply
to the spell user in that location. If the character in the previous
example were behind cover, she would have an Armor Class of
25 and her images would have an Armor Class of 17.
If the user has concealment from her surroundings, the
images have the same concealment. The images also look just
like the caster, and they share purely visual effects such as the
blur or displacement spell. If the mirror image user is also
using either of these effects, an attack aimed at an image has
the same miss chance an attack aimed at the caster has.

So striking the apparent location of a displaced figment still misses the actual location of the figment; there is a 50% miss chance to strike a displaced figment.

My initial impulse was to agree with Thanee, but since other forms of cover don't stack, I've changed my mind. The displacement overrides blur.

Thanks Hypersmurf. That helps a lot. I think that my character is just going to ignore the blur spell then. I was asking this because I was planning how to help my caster stay alive. He'll have plenty of HP's with a CON boosted to 18, but an AC of only 12 at level 9. I know there are plenty of other options too, but I think that displacement + mirror image will probably be all I need... plus I could always fly on top of that since I believe there is no restriction that the mirror images have to be on the ground.

Thanks for all the responses, they were fun to read and it is good to have multiple confirmations. I just need to reference the FAQ in the future before posting my question.

 

[Thanee]

Well, of course only one of the two concealment effects could work (displacement or blur), but I wouldn't have thought, that the images can be displaced.

Anyways, the FAQ is pretty clear on that matter.

It's worth noting that displacement says that it is an effect LIKE concealment, and lists one of the ways in which it differs.

Which would be a point for both spells having full effect - ie 20% miss chance then a 50% miss chance...
