Crystallomancy

This spell causes a clear or translucent crystalline gemstone to serve as a scrying device. The spell does not function unless the priest is in good standing with Corellon Larethian. The gemstone becomes similar to a crystal ball. For every 1,000 gp value of the gemstone, the priest may scry for 1 round, up to a maximum of 1 hour (60 rounds).
For every three levels of the priest above 7th, it is possible to cast a single divination spell of 4th level or less into the area under observation (thus, one at 10th, two at 13th, three at 16th, etc.). Only detection spells, such as detect magic and detect evil/good, may be so cast, as adjudicated by the DM.
