Here is the description I know of true seeing:


Divination
Level: Clr 5, Drd 7, Knowledge 5, Sor/Wiz 6
Components: V, S, M
Casting Time: 1 standard action
Range: Touch
Target: Creature touched
Duration: 1 min./level
Saving Throw: Will negates (harmless)
Spell Resistance: Yes (harmless)

You confer on the subject the ability to see all things as they actually are. The subject sees through normal and magical darkness, notices secret doors hidden by magic, sees the exact locations of creatures or objects under blur or displacement effects, sees invisible creatures or objects normally, sees through illusions, and sees the true form of polymorphed, changed, or transmuted things. Further, the subject can focus its vision to see into the Ethereal Plane (but not into extradimensional spaces). The range of true seeing conferred is 120 feet.

True seeing, however, does not penetrate solid objects. It in no way confers X-ray vision or its equivalent. It does not negate concealment, including that caused by fog and the like. True seeing does not help the viewer see through mundane disguises, spot creatures who are simply hiding, or notice secret doors hidden by mundane means. In addition, the spell effects cannot be further enhanced with known magic, so one cannot use true seeing through a crystal ball or in conjunction with clairaudience/clairvoyance.

Material Component
An ointment for the eyes that costs 250 gp and is made from mushroom powder, saffron, and fat.


Does see through illusions means that someone who use true seeing is immune to the spells Phantasmal Killer and Wierd?
I think that even though you can see through illusion you still see the illusion and you are still affected by the spell but a friend of mine understood that the caster knows that it is just an illusion becouse he see through it and therefore he is immune to it. Of course the DM is always right but I want to know your opinions about the subject.

Here my opinion,

Phantasmal Killer and Weird are not just illusions,t he're phantams.

"A phantasm spell creates a mental image that usually only the caster and the subject (or subjects) of the spell can perceive. This impression is totally in the minds of the subjects. It is a personalized mental impression. (It’s all in their heads and not a fake picture or something that they actually see.) Third parties viewing or studying the scene don’t notice the phantasm. All phantasms are mind-affecting spells."

I'd say True Seeing would be bypassed compleatly by phantasms.

[RedSlayer]

I agree with this. Phantasms' are essentially mind-affecting effects.

The other sub-schools of illusion would be negated for the most part, however.

Well tachnically phantasms are part of the illusion school which make them illusions. The spell description sais the subject "sees through illusions" (a quote from the spell description) so it seems that it is supose to include all spells from the school of illusion.

"A phantasm spell creates a mental image that usually only the caster and the subject (or subjects) of the spell can perceive. This impression is totally in the minds of the subjects. It is a personalized mental impression. (It’s all in their heads and not a fake picture or something that they actually see.) Third parties viewing or studying the scene don’t notice the phantasm. All phantasms are mind-affecting spells."

Maybe if the subject of a phantasm is protected by true seeing he see through the phamtasm (since it is an illusion) and can't realy percive it.

It's not an real thing, it is an illusion, and even if it is a mind affecting spell, if I remember the spell description(sorry, don't have the books handy right now), The person in question has to see the phantasmal killer in all its horror for It to effect them. Then they basicly have a heart attack. So it really come down to how the dm defines seeing through illusions. Can they just NOT see it, or do they still see it, just more of as a haze?
Even this way I would think it at LEAST give a bonus on the dc for the save.

[Dthclaw]

Part of the issue is a piss-poor choice of wording. One interpretation is that the line in question refers to the entire school of illusion; the other is the one most thus far have chosen to subscribe to. Unfortunately, there's very little information within the spell description to make a clear choice.

I think the interpretation that it only applies to certain parts of the Illusion school would be the more prudent one, as it offers both less of a decisive advantage (not to say it doesn't offer an enormous advantage to begin with) and it seems to fit more with the spirit of the spell's description if not the letter of it.

I remember seeing this post last year, but didn't know enough about it to venture an opinion. However, now that I reread the spells, I'm going to have to disagree with previous posters. Hopefully my argument will make sense (even if it isn't convincing).

From the PHB

pg. 173 - 174
Saving Throws and Illusions (Disbelief):
"Creatures encountering an illusion usually do not receive saving throws to recognize it as illusory until they study it carefully or interact with it in some fashion....A successful saving throw against an illusion reveals it to be false, but a figment or phantasm remains as a translucent outline....A character faced with proof that an illusion isn't real needs no saving throw."

pg. 260
Phantasmal Killer:
"Only the spells subject can see the phantasmal killer....The target first gets a Will save to recognize the image as unreal."

My argument is that even though only the target can see the phantasmal killer, it is still is a visual perception for that target; the target thinks he really does see something (I know that is confusing, since it is just in your mind, but, from what I understand, someone who is hallucinating thinks they are really seeing something). True Seeing allows the target to see things as they actually are. It doesn't say that the target doesn't know the illusion is there. So in the case of the phantasm, the target sees the phantasm, but he sees it as a phantasm, not as a nightmare. he is faced with proof of the illusion, and therefore he doesn't need the saving throw. If he doesn't need the saving throw, it should count as an automatic success.

I think that in this case, WotC really did mean Illusions, and not just some subclasses of Illusions. However, not all illusions have visual components.

That being said, all phantasms are definitely mind-affecting spells according to PHB pg 173.
