How about a spell three ways? First for DnD 5e
Casting Time: 1 action
Range: 60 feet
Components: V, S, M (a bit of fulgurite )
Duration: Concentration, up to 1 minute
A 5-foot-diameter sphere of lighting appears in an unoccupied space of your choice within range and lasts for the duration. Each round, you may make a ranged spell attack emanating from the sphere at a creature within 30 feet. Upon hitting the creature, the creature takes 4d8 lightning damage, and you make a two more ranged spell attack at two different creatures in range of the first target. Upon a hit, each secondary target takes 4d8 lightning damage. You do not make the secondary attacks again. This attack takes no action.
As a bonus action, you can move the sphere up to 30 feet. As an action, you may make a second attack with the spell with the secondary attacks performed as normal.
When you move the sphere, you can direct it over barriers up to 5 feet tall and jump it across pits up to 10 feet wide. The sphere sheds bright light in a 60-foot radius and dim light for an additional 30 feet.
At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 4th.
