Chilled Bones

A frigid beam of blue-white light streaks toward a creature within range. Make a ranged spell attack against the target. On a hit, it takes 1d4 cold damage, the target must make a Constitution saving throw. On a failed save, it is stunned until the start of your next turn.

The spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
