Ice Knife

You create a shard of ice and fling it at one
creature within 60 feet. Make a ranged
spell attack against the target. On a hit
the target takes 1d10 piercing damage.
Hit or miss, the shard then explodes.
The target and each creature within 5
feet of the point where the ice exploded
must succeed on a Dexterity saving
throw or take 2d6 cold damage.
