Aqua Bullet

You create small concentrated orbs of water and launch them at one or multiple creatures within range. You may, up to the amount of d4, divide amongst your selected target(s). (2d4 equal 2 targets maximum etc.) Make a ranged spell attack for each new target. On a hit, the target takes 2d4 force damage. 

The spell's damage increases by 1d4 when you reach the 5th level (3d4), 11th level (4d4), and 17th level (5d4).
