Energy beam

As an action, you target one creature you can see within 90 feet of you. The target must succeed on a Dexterity saving throw or take 1d8 acid, cold, fire, lightning, or thunder damage (your choice).

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