Portals exist in dungeons as an alternate means of ascending/descending levels. They appear visually in the game display window as rectangles on the floor and/or ceiling. A key, depending on the computer system used to play the game, allows the party to travel, although ascending is impossible without the Levitation or Major Levitation spells active and descending without either of these spells results in (minor) damage to all party members.

It is worth noting that some portals are one-way only.
