A billowing cloud of misty vapors is created by the use of this spell. It radiates outward from the caster to fill a 20-foot radius spherical area above and below the caster's ground level, penetrating all obstructions that are not airtight. At the end of the round of casting, the magic takes effect, and the mist changes in hue from blue-gray to green, becoming poisonous. All breathing creatures within the area of effect not possessing a (magical) separate air supply—except the caster, who is immune to the effects of his or her own murderous mist— must immediately save vs. spell. Those who successfully save are unharmed. Those who do not suffer 2d4 points of damage from the vapor, which is corrosive to flesh but does not affect clothing or items. Creatures that can't move out of the area of effect within the round take a further 1d4 points of damage on the following round as the vapors begin to combine with the air and disappear. Tiny creatures such as those making up an insect swarm or creeping doom are killed by the mist on contact.
The globe of murderous mist is a magically bound, stationary, precise area unaffected by natural or magical winds. Dispel magic or part water will cause it to disappear before expiration of the spell, and various magic or items (such as rope trick or a portable hole) will protect an individual by providing escape from the mist, but it is otherwise unaffected by natural or magical forces.
Notes: Uncommon or rare spell from the Forgotten Realms setting. Known to be in Sabirine's Specular.
