Al Huma

You create a sharp long spear of ice and shoot 50ft in straight line. Each creature in a 25-foot-radius sphere centered on that point must make a Dexterity saving throw. A creature takes 5d8 cold damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
