Advanced Dungeons & Dragons 2nd Edition Wiki

By casting this spell, the wizard creates a billowing wall of misty vapors in any area within the spell range. The wall of fog obscures all sight, normal and infravision, beyond two feet. The caster may create less vapor if he wishes.

The wall must be a roughly cubic or rectangular mass, at least ten feet wide in its smallest dimension.

The misty vapors persist for three or more rounds. Their duration can be halved by a moderate wind, and they can be blown away by a strong wind.

The material component is a pinch of split dried peas.
