Wildwind

Creates a 150-ft. line of moving lights at a point within 100 yards. From the second round the caster steers it (straight or up to 45 degrees to either side, 60 ft/round); once moving it can't be stopped, only cancelled or dispelled. Creatures struck take 2d6 damage; any spellcaster struck mid-cast automatically triggers a wild surge (Table 2), and charged magic items touching it discharge a charge and also surge. Lasts 1d3 turns.
