When a priest casts this spell, a green ray springs from his outstretched hand and unerringly strikes a creature within line of sight and the range of the spell, covering the subject with a shimmering emerald field that completely blocks bodily extradimensional travel. Forms of movement barred by the dimensional anchor include blinking, dimension door, etherealness, gate, phasing, plane shift, maze, shadow walk, teleportation, and similar spell-like or psionic abilities. The field persists for one turn plus one round per caster level and has no effect other than blocking extradimensional travel. The dimensional anchor does not interfere with the movement of creatures in astral form, nor does it block extradimensional perception or attack forms such as a basilisk's gaze.
Notes: Uncommon for clerics (PO:SM).
