An ice ball that grows more and more jagged as it travels is launched from your hand in a straight line and upon impacting a creature it explodes in icy shrapnel. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 4d6 piercing damage on a failed save, or half as much damage on a successful one. Each creature in a 30 ft cone in front of the impact must make a Dexterity saving throw. A target takes 4d6 cold damage and their movement is halved, or half as much damage on a successful one and they are not slowed.

The ice covers the ground in the affected area making it difficult terrain. To move full speed one must make a DC 12 Dexterity saving throw or fall prone.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 piercing for each slot level above 3rd.
