Bjork's Flying Icicle

You create a shard of ice and fling it at one creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 piercing damage and the shard explodes. Each creature within 5 feet of it must make a Dexterity saving throw or take 2d6 cold damage, or half on a success. The target immediately fails this saving throw. 

On a miss, the shard flies 1d6 tiles (5ft squares) away from the intended destination.  It will explode at its new destination and deal its area damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the cold damage increases by 1d6 for each slot level above 1st.
