Spark Storm

Area
Creates a normal Windstorm, with a dangerous addition: every turn Lightning strikes one random victim in the area of effect. To resolve the bolt’s attack, roll against the caster’s Spark Storm skill, without any range adjustments. The victim gets an active defense, as usual.
At the GM’s option, the lightning strikes may not be completely random: tall targets may be at more risk than short ones, and metal armor may tend to attract the lightning. Mages who use this spell know what the true rules are in their world.

Duration: 1 minute after reaching full strength.
Base cost: 2 (1d-1 Lightning), 4 (2d-2 Lightning) or 6 (3d-3 Lightning) to cast. Half that to maintain.
Time to cast: The storm starts immediately, but the caster must concentrate for a number of seconds equal to the storm’s radius in yards to bring the storm to full strength.
Prerequisites: Windstorm and Lightning

Item
Staff, wand, or jewelry. Usable only by mages.
Cost to create: 300 energy, $500 in platinum ,and a $500 opal.
