Mystra's Miasma (Wiz 9; Abjuration, Evocation)
Range: 60 yds.
Components: V, S, M
Duration: 1 turn/level
Casting Time: 9
Area of Effect: 30 yds. + 2 yds./level radius
Saving Throw: None
When cast, thick shimmering silver mists billow out from the center to instantly fill the area of effect, and the miasma lessens all physical movement and magic within it's mists. Like heavy fog blanketing a sea town, it mutes much activity and makes it difficult to see within its area.
First and foremost, Mystra's miasma limits all visual senses (infravision included) to a maximum range of 30 yards while inside the area of effect. This field also slows all entrants' movement of all types by half, and maneuverability classes are dropped by one. The miasma also affects all active magic and spell effects so all operate at absolute minimums (1 point of effect per die; i.e., a 7th-level caster's fireball only deals 7 points of damage) or at -2 against permanent effects (bracers of defense AC3 now act as AC 5, etc.).
Multiple castings have no additional effect on the area or its effects on those within it (i.e., no quartering movement), they will add on to the duration of the mists and the spells standard effects.
Notes: Known by the Chosen of Mystra.
