This spell summons a Class III intelligent mist from the elemental plane of air. The creature has spellcasting ability, and can cast its own spells as well as any spells given to it by the wizard (if the wizard had the spells memorised when he cast the Magic Mist spell).
Other than this increased ability, these mists conform to the attacking mist spell.

Intelligent mists are normally solitary creatures who exist on the elemental plane of air. They normally only occur on the prime material plane when summoned by a talking mist, attacking mist or magic mist spell, which summon a mist of class I, II, and III respectively.
Combat: messenger mists (class I) only attack in self-defense, and even then they can avoid a conflict by dissipating. Guardian mists (class II) attack by making whip-like appendages semi-corporeal. On an attack roll of 20, the mist has succeeded in either suffocating its enemy which causes 1d6 point damage for each roll (no attack roll necessary) until the victim is dead or the mist is destroyed.
When a mist's hit points reach 0 on the prime material plane, the creature is not killed, but is sent back to it own plane. Killing it on its own plane does kill it.
Monarch mists (class III) have the following spells which they can cast once per day: wall of fog; fog cloud; darkness, 15-foot radius; gust of wind; wind wall and lightning bolt. They cast these as 7th-level wizards.
The material component for a magic mist spell is a piece of paper with the orders for the mist written on it, which must be burnt in the casting. The ink used must be extracted from rare berries, worth at least 20 gp.
