This spell creates an ethereal passage through wooden, plaster, or stone walls, but not other materials. The phase dooris invisible and inaccessible to all creatures except you, and only you can use the passage. You disappear when you enter the phase doorand appear when you exit. If you desire, you can take one other creature (Medium 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 you see through it without using it. Thus, the spell can provide an escape route, though certain creatures, such as phase spiders, can follow with ease. A gem of true seeing or similar magic reveals the presence of a phase doorbut does not allow its use.
A phase dooris 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.
You can allow other creatures to use the phase doorby setting some triggering condition for the door. Such conditions can be as simple or elaborate as you desire. They can be based on a creature’s name, identity, or alignment, but otherwise must be based on observable actions or qualities. Intangibles such as level, class, HD, and hit points don’t qualify.
Phase doorcan be made permanent with a permanency spell.
