Corrupted Blast

A beam of darkened energy streaks toward a creature within range from the mouth of the skull. Make a ranged spell attack against the target. On a hit, the target takes 1d10 necrotic damage. If the attack roll is a critical, they must succeed a Wisdom saving throw or become stunned.

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.
