(Alteration, Evocation)

Components:  V, S, M
Duration:  1d4 rounds + 1 round per level
Casting Time:  7
Area of Effect:  20-foot radius
Saving Throw:  Special

This spell creates a 20-foot radius cloud of purple and black smoke up to 10 feet away per level of the wizard. The smoke is impervious to all forms of vision. The smoke cloud is actually extradimensional, employing forces similar to distance distortion. The internal diameter of the cloud is 100 to 150 feet; furthermore, the vapours contain a powerful misdirection spell (saving throw at -2) which prevents those inside from wandering out. The cloud persists for 1d4 rounds plus one round per level of the wizard, after which it disperses. Only a strong wind will break it up prematurely. Extradimensional devices in the cloud are unaffected.
The material component is a black pearl worth at least 500 gp and a bent compass needle.
