Scintillating Sphere

This spell causes a grape-sized sphere to appear near the caster. The sphere than travels in a straight line at high speed to a location in sight of the spellcaster.

Upon reaching this location, the sphere pulses outward twice and then disappears. Damage is caused by the second pulse only, and is electrical. Damage caused is 1d6 for every level of the caster, to a maximum of 10d6 (save vs. spell for half). Saving throws for items are made vs. lightning.

The caster chooses the location by pointing at the spot and speaking the distance for the sphere to travel. The sphere pulses at the distance spoken.

The material components are a small glass sphere and a pinch of iron oxide. The components are consumed in the casting.
