Chromatic Lash

You flick a streak of vivid, magical pigment toward a creature you can see within range. The pigment lashes out like a whip of living color. Make a ranged spell attack against the target. On a hit, the target takes 3d6, chosen from acid, cold, fire, lightning, or poison (your choice when you cast the spell). Additionally, the target is splashed with lingering color until the end of your next turn. The next attack roll made against the target before then has advantage, as the bright pigment outlines its form.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
