Actual Chill Touch

Your hand is enveloped in a layer of frost. Make a melee spell attack against the target. On a hit, the target takes 1d8 cold damage, and its speed is reduced by 5ft until your next turn. 

The spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
