Bubbling Mote

You waft a mote of potent acidic energy at a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d6 acid damage as the mote contacts their body. The target must make a Constitution saving throw or take an additional 1d6 acid damage as the acid causes their flesh to bubble and sear away.

Each instance of this spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
