Mists of Ghaunadaur

By means of this spell, the caster can cloak himself or herself in mauve or violet mists that eddy and flow, foiling attacks for which one must see the target (including magic missile), and thwarting infravision and heat-based detection abilities. The caster receives a +2 Armor Class bonus. The mists of Ghaunadaur can be pierced by true seeing. The caster's vision is unhindered by the enveloping mists.
