Wall of Fog

By casting this spell, the illusionist creates a wall of misty vapors in whatever area within the spell range he or she desires.

The wall of fog obscures all sight, normal and/or infravisual, beyond 2-ft.

The area of effect is a cube of 2" per side per level of experience of the spell caster.

The misty vapors persist for 3 or more rounds unless blown away by a strong breeze (cf. gust of wind). 

The material component is a pinch of split dried peas.
