Weather Weaving

Spell Type: Utility; Mana Cost: 8 MP; TN: 16
Test: None; Requirements: None

You shape and direct the weather in an area with a radius equal to your Magic in miles. You can choose any natural weather condition normally possible in the area for the given time of year (so you cannot make it snow in the middle of summer, for example, or rain in the desert). The weather forms within eight hours of your casting, so generally only limited changes are possible. You can make it warmer or colder by about 20 degrees Fahrenheit (12 degree Celsius), cause it to rain or snow (or stop doing so), or make the sky overcast or clear.

Multiple castings (and expenditures of mana) over multiple days can extend the spell’s effect, creating more dramatic shifts in the weather. Note that you do not control the weather from moment to moment. Once you have set it in motion, it follows its natural course.
