The Voids Retribution

A beam of cosmic energy aimed toward a creature within range. On a hit, the target takes necrotic damage.

The spell creates more than one beam when you reach higher levels. It creates two beams at 5th level, three beams at 10th level, and six beams at 15th level. You can direct the beams at the same target or at different ones, but make a separate attack roll for each beam.
