(Evocation)

Range:  10 yards + 5 yards per level

Duration:  1 round per 3 levels
Casting Time:  6
Area of Effect:  10 square feet + 5 square feet per 2 levels
Saving Throw:  1/2

This spell will cause a sheet of corrosive acid to fall from the sky (actually, it will appear 10 feet over the target spot). All creatures or objects underneath will be subject to its effects. The acid will corrode wood, metal, cloth, and flesh. The initial inundation will cause 1d6 damage per level (with a maximum of 10d6). A successful saving throw will cause half damage, and adds +1 to subsequent saving throws. All items exposed to the acid must also save. If a magical item saves successfully, no further saving throws are necessary.
Armour loses one point of Armour Class per round. If it loses all of its points, it disintegrates and falls to the ground. Weapons lose one point per round. The number of points is determined by size (large: 3, medium: 2, small: 1). When all points are gone, the weapon is too weak to use in combat.
All damage done to items (other than loss of magical properties), can be repaired with a mend or the like, unless the item was destroyed. Subsequent damage to flesh is 1d6 per round. All subsequent damage can be avoided if victims immerse themselves in water, to wash off the acid.
The material components of this spell are rain water and sulphur.
