Ray of Frost

A frigid beam of blue-white light streaks toward a creature within range. Make a ranged spell attack. On a hit, it takes 1d8 cold damage, and its speed is reduced by 10 feet until the start of your next turn. Damage increases to 2d8 at 5th level, 3d8 at 11th level, and 4d8 at 17th level.
