Arcane Beam

A beam of pure arcane energy streaks toward a creature within range. It takes the form of your choice before reaching the target. Make a ranged spell attack against the target. On a hit, the target takes 1d8 + primary casting modifier of fire, cold, lightning, thunder, acid, poison, radiant, necrotic, psychic, or force damage.

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