0-level (Cantrip) Conjuration
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 1d8 cold damage, and its speed is reduced by 10 feet until the start of your next turn. The spell's damage increases by 1d8 when you reach 5th level ( 2d8 ), 11th level ( 3d8 ), and 17th level ( 4d8 ).
