Make a ranged spell attack against a creature you can see within range. On a hit, the target takes 4d8 cold damage and ice is spread in a 5-foot radius around it, creating difficult terrain. Additionally, the projectile spreads ice bellow its trajectory to the target, creating a 5 feet wide line of difficult terrain. You can choose any number of creatures you can see within range to be unaffected by the difficult terrain created by this spell.
