Cindervines

You evoke a long, vine-like whip made of ash and cinder in your free hand. The vine is similar in size and shape to a whip, and it lasts for the duration. If you let go of the whip, it disappears, but you can evoke the whip again as a bonus action. 

You can use your action to make a melee spell attack against a creature within 15 feet of you. On a hit, the target takes 2d6 fire damage. If that creature is currently concentrating on a spell, the damage is doubled and the creature has disadvantage on the concentration check.

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