Aqua Lance

You manifest and launch a piercing jet of sea water at a target within range. Make a ranged spell attack against the target. On a hit, it takes 1d6 piercing damage, and it must make a Charisma saving throw against your spell save DC, becoming frightened of you until the start of your next turn on a failed save.

The spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
