Arctic Spear

Description:  You conjure a 10ft long spike of ice and launch it in a direction of your choice. Any creature in its path must make a Dexterity saving throw or take 2d12 cold and 5d12 piercing damage, taking half as much on a successful save. If the creature fails its saving throw or is killed by this spell, the spear will pierce through them and continue on its path until it is stopped or reaches its maximum

range.
