Cinder-Vines

You create a long, vine-like whip made of cinders that lashes out toward a creature that you can see within range. The target must make a Dexterity saving throw. On a failed save, the target takes 4d6 fire damage and is stunned.On a successful save, the target takes half as much damage and suffers none of the spell’s other effects.

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