Windstorm

Area
Create a circular windstorm with an “eye” of calm inside (a good place for the caster to stand). The radius of the eye can be up to half that of the storm – or smaller, if the caster wishes. By concentrating, the caster can move the storm any distance up to its own diameter per second; the eye moves with it. The caster may move up to half his normal Move inside the eye while concentrating on this spell.

Anyone within a full-strength Windstorm must roll vs. ST once per second to avoid being knocked over by the wind. All DX-based skills are at -5, and ranged attacks are at a -10 penalty for every yard of the windstorm they pass through.

For double energy cost, the caster may create a more powerful windstorm, like a tornado. ST rolls to remain standing in such a gale are at -5, ranged attacks through it are impossible, and visibility inside it is a yard at best. This powerful windstorm physically lifts and hurls objects up to 30 pounds per yard of radius.

Duration: 1 minute after reaching full strength.
Base cost: 2. Half that to maintain.
Time to cast: The storm starts immediately, but the caster must con- centrate for a number of seconds equal to the storm’s radius in yards to bring the storm to full strength.
Prerequisite: Shape Air.
