Spark Shower

This spell creates a cloud of sizzling purple sparks, originating from the caster's hands and spreading outward in a cone 20 feet long and 10 feet wide at the far end. All creatures in the area of effect take 4d4 points of electrical damage if in contact with metal (that is, wearing metal armor or holding metal weapons) or 2d4 points otherwise.

The material components are a piece of flint and a piece of iron, which are struck together when casting the spell.
