Corrosive Blast

You shoot a sticky blob of acid at a creature you can see within range. Make a ranged spell attack against the target. On a hit, the acid sticks to your target dealing 1d6 acid damage. At the beginning of the target's next turn, the target must make a Dexterity saving throw or take an additional 1d4 acid damage.

This spell’s initial damage increases by 1d6 and secondary damage increases by 1d4 when you reach 5th level (2d6, 2d4), 11th level (3d6, 3d4), and 17th level (4d6, 4d4).
