Waterball

You cast an extremely cooled down waterball at one creature or object within range. Make a magic ranged attack roll against the target. On a hit, the target takes 1d10 cold damage as the water explodes and instantly freezes when it hits the target. 

This spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
