Effect

This spell creates a wall of dark mist that is 1 foot in thickness, 20 feet wide, and 15 feet tall. When something comes in contact with it, it is repelled from the wall.
Small objects and creatures are thrown 20 feet per caster level and disintegrated. If a successful saving throw versus spell is made, they are repelled half as much and stay in one piece unless the destination prevents that.
For medium creatures and objects, they are repelled 15 feet per caster level, save for half the distance.
Large creatures or objects are repelled 10 feet per caster level, save for half the distance.
Giant creatures or objects are repelled 5 feet per caster level, save for half the distance.
Anything larger must save versus spell to pass through.
If the spell is centered on a creature or object, they must save versus spell or the distance and damage taken will be double. If the spell is cast on a medium creature or object, they must save or be disintegrated.
