True Seeing {Wizard}

When the wizard employs this spell, it confers upon the recipient the ability to see all things as they actually are. The spell penetrates normal and magical darkness. Secret doors become plain. The exact location of displaced things is obvious. Invisible become visible. Illusions and apparitions are seen through. Polymorphed, changed, or enchanted objects are apparent. (The real form appears translucently superimposed on the apparent form: a gold dragon polymorphed to human form would appear human with a ghostly dragon looming over the human form.) Unlike the clerical version of this spell, the recipient cannot determine alignment. The recipient can focus his vision to see into the Ethereal plane or the bordering areas of adjacent planes. The range of vision conferred is 60 feet. True seeing does not penetrate solid objects: it in no way confers X-ray vision or its equivalent. Furthermore, the spell effects cannot be enhanced with magic.

The material component must be rubbed on the eyes during the casting of the spell.

Note that unlike the priest spell of the same name, the wizard version of true seeing is not reversible.
