School: Chronomancy (Divination)
(Intended for use with the Chronomancer subclass)
This spell allows the caster to scry people or places in other times. This operates within the caster's mind, and any innate abilities or permanent spell effects placed on the caster apply. Spells like Comprehend Languages, Read Magic, and Darkvision work through Temporal Eye. Spells like Tongues, Detect Magic, Detect Good/Evil, and Message have a 5% chance per caster level of working correctly through the Temporal Eye. Spells such as Locate Object, Domination, Suggestion, and True Seeing have a 5% chance per 2 caster levels of working correctly through the Temporal Eye. The chance for scrying success, as well as the chance for detection, are the same as those for the Scrying spell. Scrying into a different time offers no further penalty. In any case, a spell or effect capable of detecting scrying attempts will detect a Temporal Eye, but does not necessarily reveal its anachronistic nature.
There are many material components required. The eye of a far-seeing creature (eagle, hawk, etc) is held in the left hand. Blood from a Time Dog is mixed with a concoction of alcohol, sodium, and strychnine. Finally, hundreds of Strands must be collected from the demiplane of time, enchanted, woven into a veil, and worn over the face. All items are consumed by the spell, except the veil, which may be reused.
Based on the 2e AD&D spell of the same name, from the Chronomancer suppliment (TSR 9506).
