Time: 10 minutes	Key Skill: Arcana
Duration: 1 hour

You create a passage through wooden, plaster, or stone walls, but not through metal or other harder materials. The length of the passage depends on the arcane check that creates it. If the wall’s thickness is more than the depth of the passage created, then a single passwall simply makes a niche or short tunnel. When passwall ends, creatures within the passage are ejected out the nearest exit. Consider the effect a conjuration for dispelling purposes. Place the passwall as if it was a wall, only it can only be placed in squares of blocking terrain.
