|This spell creates a gate allowing long-distance travel in relatively ordinary environments (i.e., the Dungeon only). The portal lasts long enough for the caster and nearby creatures to enter. Casters are never taken past the level limits of the current area.|
Portal was a level 7 Translocations spell which allowed the caster to move up to 9 floors up or down through the Dungeon. The spell had to be cast on a standard floor tile and always delivered the player to a staircase of the floor they selected. Standing on a staircase, doorway, or over water would make the spell fail, as would being in a dungeon branch. If the player attempted to move beyond the limits of the dungeon, they would be prompted to select a different floor.
This spell stopped working once you picked up the Orb of Zot.
Portal was formerly found in the following spellbook:
Portal was removed from the game in 0.8.0.
