School: Chronomancy (Divination)
(Intended for use with the Chronomancer subclass)
Range: 90 ft / level while cast is in Reality, Unlimited while on the demiplane of time

When this spell is cast, the caster is attuned to turbulence in the timestream and can scan a 90-degree by 90-degree area (one eighth of a sphere) each round while concentrating. After locating an anomaly, the severity can be determined by concentrating on it for an additional round. The caster has a 5% chance per level to recognize the cause. On the demiplane of time, distance is not a factor, and the spell detects the nearest source of turbulence in any scanned direction. On a Prime Material, Elemental, or Outer plane, the range is 90 feet per level. In both cases, sight is also a limiting factor.  The spell can effectively be maintained for as long as the caster concentrates.

Based on the 2e AD&D spell of the same name, from the Chronomancer suppliment (TSR 9506).
