Effect: This powerful spell enables the caster to
bring into being a cube of force, but it is unlike the magic item of that
name in one important respect: The forcecage does not have solid
walls of force; it has alternating bands of force with 1/2’ gaps between.

Thus, it is truly a cage rather than an enclosed space with solid walls.
Creatures within the area of effect of the dweomer are caught and
contained unless they are able to pass through the openings - and of
course all spells and breath weapons can pass through the gaps in
the bars of force of the forcecage. Furthermore, creatures with a magic
resistance can apply that resistance in a single attempt to pass
through the walls of the cage. If resistance fails, then the creature in
question is caged. Regardless of success, any and all other creatures
also in the area of effect of the spell are trapped unless they also have
magic resistance which allows them to escape. The forcecage is also
unlike the solid-walled protective device, cube of force, in that it can
be gotten rid of only by means of a dispel magic spell or by expiration
of the dweomer.

By means of special preparation at the time of memorization, a forcecage
spell can be altered to a forcecube spell. Forcecube has one eighth
the area of effect (a cube 1 “ on a side), and the dweomer then
resembles the magic of a cube of force in all respects except for the
differences between a cast spell and the magic of a device, including
the methods of defeating its power.

Although the actual casting of either application of the spell requires
no material component, the study of the spell required to commit it to
memory does demand that the magic-user powder a diamond of at
least 1,000 gp value, using the diamond dust to trace the outlines of
the cage or cube he or she desires to create via spell casting at some
later time. Thus, in memorization, the diamond dust is employed and
expended, for upon completion of study, the M-U must then
toss the dust into the air and it will disappear.
 

WSG: The spell description does not specify that the
cage must be anchored to a solid surface. There is a chance
equal to 5% per level of the caster that the spell could be used to
halt a falling character or creature in mid-air (assuming, of
course, that the target is within range when the spell is discharged).
Failure on this chance indicates that the intended target
was missed and the forcecage is formed around thin air.
Success indicates that the target is prevented from falling any
farther, and he only takes damage as for a 20-foot fall (the length
of one side of the cage). There must be a way to rescue the character
by other means before the duration expires, or his fall will
resume from that point when the cage disappears. It is possible,
for instance, to pass a rope through the bars of the cage; the
character can tie it around his waist and then be hauled to safety
when the duration expires or the magic is dispelled.

Q: The description of the forcecage
spell says that a creature with magick
resistance can make only one
attempt to get out. Is such a creature
limited to one attempt to pass
through the bars in either direction,
or can it force its way into the cage
and then try to get out again?
A: A creature with magic resistance can try
to force its way into a forcecage once only
(or once per day if the cage is permanent).
It can also attempt to escape the cage
using its magic resistance once (or once
per day). A creature could be trapped
after entering the cage in this manner.
Note that the forcecage does not prevent
teleportation, astral projection, or other
forms of magical travel, nor does it prevent
its occupant(s) from polymorphing
into something small enough to pass
through the ?bars.?
