Coward's Reprieve (3.5e Spell)

You banish yourself into an extradimensional labyrinth of force planes. Each round on your turn, you may attempt a DC 20 Intelligence check to escape the labyrinth as a full-round action. If you don’t escape, the maze disappears after 10 minutes, forcing you to leave.

On escaping or leaving the maze, you reappear where you were when the coward's reprieve spell was cast. If this location is filled with a solid object, you appear in the nearest open space. Spells and abilities that move a creature within a plane, such as teleport and dimension door, do not help you escape a coward's reprieve spell, although a plane shift spell allows you to exit to whatever plane is designated in that spell. Minotaurs are not affected by this spell.
