This spell creates an ethereal passage through wooden,
plaster, or stone walls, but not other materials. The phase door
is invisible and inaccessible to all creatures except the
character, and only the character can use the passage. The
character disappears when the character enters the phase door and
appears when the character exits. If the character desires, the
character can take one other creature (Medium-size or smaller)
through the door. This counts as two uses of the door. The door
does not allow light, sound, or spell effects through it, nor can
the character see through it without using it. Gems of true
seeing and similar magic reveal the presence of a phase door but
do not allow its use.
A phase door is subject to dispel magic. If anyone is within
the passage when it is dispelled, he is harmlessly ejected just
as if he were inside a passwall effect.
A phase door can be made permanent with a permanency spell.
The character can allow other creatures to use the phase door
by setting some triggering condition for the door. Such
conditions can be as simple or elaborate as the character
desires. They can be based on a creatures name, identity,
or alignment, but otherwise must be based on observable actions
or qualities. Intangibles such as level, class, HD, and hit
points dont qualify.
