Storm Summoning

Usage: cast storm-summoning
Save: None
Element: Air

When cast inside, this spell conjures up a miniature thunderstorm to harm the caster's foes, doing a moderate amount of damage. However, when cast outside, this spell influences local weather patterns to create an actual raging storm in the caster's area, which inflicts significantly more damage. The side effect is that the storm remains in the area, which may have other effects.
