A grey ray flecked with red springs spings
from your outstretched hand. You must make a range touch attack to hit
target. A target struck is covered with a glittering red field that
usurps some forms of planar travel Forms of travel usurped by desert
diversion include dimension door, etherealness, ethereal jaunt, gate,
greater teleport, plane shift, shadow walk, teleport, teleport object,
teleportation circle, and similar spells, spell like abilities, and
psionics. If the subject of the desert diversion casts one of the above
spells, she and those traveling with her are diverted. This spell can
also be cast on a gate or teleportation circle, thereafter diverting
all who use the affected spell for the duration of desert diversion.
Subjects are diverted to a random wasteland location. There
is a one in eight chance of a wandering encounter. Until desert
diversion ends or is dispelled, the subjects of the spell cannot use
any of the abovementioned spells to travel from the area. If they try,
casting simply returns them to the same spot in the middle of the
desert. When the duration ends, they are free to teleport away but
those abilities requiring you to know where you do not function unless
teh haracter can determine that.
