Aeonic Ruinga

You create powerful explosive spheres of magical force that darts forth from your fingertip and strikes the target creature within range creating a 15ft radius explosion of energy hitting all that is in the area of it. Make a ranged spell attack against the target. On a hit, the target takes 1d8+8 force damage.

The spell creates more than one small spheres when you reach higher levels: two spheres at 5th level, three spheres at 11th level, and four spheres at 17th level. You can direct the spheres at the same target or at different ones. Make a separate attack roll for each sphere.
