Teleport Block
(Abjuration)

Range:  10 yards per level
Components:  V, S, M
Duration:  1 hour per level
Casting Time:  1 turn
Area of Effect:  One thousand cubic feet per level
Saving Throw:  Special

This spell prevents teleportation into or out of the region specified by the wizard, which may be of any shape and any size, up to 1000 cubic feet per level of the abjurer. No character can enter or leave the region by means of dimension door, teleport, or other-planar travel. Teleportation within the region is not restricted, and teleport without error has a chance of success equal to 1% per level of the wizard, though it has the same chance of failure as a regular teleport attempted under normal conditions. A wish will also provide transportation across the boundary, as of course will walking, riding, and flying.
Any attempt to teleport or dimension door across the block will automatically fail; all memory of the spell will be lost; and the wizard must make a system shock check or be killed by the shock of the rebound. Attempts at transplanar travel will also fail, but not in so dramatic a fashion. The material component is a glass globe.
