Passwall

A passwall spell enables the spellcaster to open a passage through wooden, plaster, or stone walls, but not other materials. The spellcaster and any associates can simply walk through. The spell causes a 5' wide x 8' high x 10' deep opening. Several of these spells can form a continuing passage so that very thick walls can be pierced. If dispelled, the passwall closes away from the dispelling caster, ejecting those in the passage.
