Is there a spell to see through illusions?
 

I've been looking around, checking the books and pyramids I have available (not as many I would like to have though) and I couldn't find a spell that can see through illusion without extraordinary conditions attached (a resisted check against the illusion's caster is ok).

Mage Sight would say the object/subject I see has a magical aura, but not that is a illusion per se.
See Secrets would see a secret passage behind an illusory wall but will not work against the illusion of a goblin walking through a corridor.

Is there something usable for that purpose (of seeing through illusions) available? It can be as specific as only works against illusions or broad similar to D&D's True Seeing spell.

There's Know Illusion, but that's not a generic sight effect, it's something you cast on a particular illusion.

That only tells if it's a illusion or creation, and you must cast the spell on it directly so you would need to know the need to cast it. I was looking for something more dynamic like the See Invisible spell.

Aura would detect illusions of living/undead creatures.

Re: Is there a spell to see through illusions?
 

Yes, but Aura has the same problem of Know Illusion, that is, you have to be actively casting it on whatever you're suspicious of. In contrast, See Invisible will let you see if something invisible passes in your line of sight while the spell is active, you suspecting it or not (although you probably suspect it since the spell is active).

You can always add one, but think carefully before you do it. See Illusion would entirely eliminate the functionality of an entire style of magic. Once you give a wizard See Illusion, or worse allow a See Illusion magic item you have entirely eliminated any use for illusion magic forever for foes and dungeons.

Maybe ETS can see through an illusion, like it can holograms and the like?

I agree, making an easy spell to tell an illusion seems a bit too easy (and cheap to purchase).

I doubt it. Magical illusions have no reason to have frames per second.

If a human creates a flower illusion, does it include the ultraviolet colors he isn't aware of? Would a bee be fooled?

Re: Is there a spell to see through illusions?
 

Probably would not include colors he isn't aware of unless he got some specific training from someone who could see them. But bees aren't very smart or picky.
