The air blackens, the shadows of the alleys lengthen, and the wind shrieks as the Shadow and Material Planes collide.
Black labyrinth causes substantial disorientation within the area it affects. Direction and distance become impossible to determine, as the world itself bends and twists.
All attacks have 50% miss chance.
Area effects with a source or target within the black labyrinth have a 20% chance of improper placement. If this occurs, the spell is 1d4 x 5 feet in a random direction from where the caster intended. To determine direction, use the rules for a missed splash weapon.
All Search and Spot checks take a -10 penalty.
Any movement, from a 5-foot step to a full run and everything between, occurs in a random direction. (Again, use the rules for a missed splash weapon to determine direction.) Reroll any result that places the creature in an "illegal" space (in another creature's area, within a wall, and so on). A random roll that results in a fall off a ledge (or similar mishap) is allowable. A successful Will save negates this particular effect, but that save must be repeated for each round of movement.
Any teleportation effects with a destination inside the black labyrinth deposit their passengers 1d% x 5 feet from the intended destination. If this would put them inside a solid object, treat as a mishap described in the teleport spell. If this would send them outside the mystery's area, roll again. A teleport effect cast within the black labyrinth and intended to transport the subject to a point outside the affected area requires a successful Will save; failure indicates that the subject instead teleports to a random point within the black labyrinth.
When within your own black labyrinth, you are immune to the last two effects (movement and teleportation) but not the others. You may attempt to guide your companions through the black labyrinth; this does not allow them to find their way automatically, but it does grant them a +4 bonus on Will saves to resist those two effects.
