Acorn Shot

You magically imbue the acorn with druidic energy and launch it at one creature. Make a ranged spell attack against the target. On a hit, the target takes 1d10 force damage. Hit or miss, the acorn then explodes and roots spring out in all directions. The target ( at disadvantage ) and each creature within 10 feet of it must succeed on a Dexterity saving throw or take 2d6 piercing damage on a fail or half damage on a success.
