Arctic Spear

You fire an icy spear, that flies in a straight line up to 10 feet in a direction you choose, before shattering into a cone of ice shards, shattering early if it strikes a creature or impacts against a solid surface. If the spear would strike a creature, that creature must make a Dexterity saving throw. On a failed save, the target takes 2d6 cold damage and 2d4 piercing damage as the spear strikes it and shatters. Any creatures within a 10-foot cone behind the the original target (or the space it shattered if it did not hit a creature) must make a Dexterity saving throw. On a failed save, the creature takes 2d6 cold damage.
