Cerulean Slicer

You manifest a blade of magical energy in your empty hand, swiping it in a wide arc. Make a melee spell attack against a target within 5 ft of you, and up to 2 other creatures within 5 ft of both you and the first target. On a hit, each target takes 1d6 force damage.

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