You create a ball of lightning that flies toward a target of your choice that you can see within range. The size of the Ball of Lightning is determined by the size of the metal ball used.
If the ball of lightning touches a solid conductive material, then any creature within a 5 feet by 5 feet sphere zone around the impact point takes half the damage of Ball of Lightning on a failed save and a quarter of the damage on a successful one. If the Ball of Lightning touches a liquid conductive material, then any creature within a 15 feet by 15 feet sphere zone around the impact point takes the original damage of Ball of Lightning on a failed save and half of the damage on a successful one.
A target must make a Dexterity saving throw. The target takes 10d8 lightning damage on a failed save, or half as much damage on a successful one.
At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, one additional bolt leaps from the ball to another target for each slot level above 6th.
* - (A metal ball of any size)
