This spell magically bars a door, gate, window, or shutter of wood, metal, or stone. The magic holds the portal fast, just as if it were securely closed and normally locked. A knock spell or a successful dispel magic spell can negate the hold portal. For a portal affected by this spell, add 5 to the normal DC for forcing the portal.
