Wildfire Whip

The purest of your emotions flood from you like a wildfire, materializing in your hand for a brief instant as a flaming whip. Make a melee spell attack or a melee weapon attack. On a hit, the target takes 1d8 of fire damage. If the target is not resistant to fire, you can also make a Strength check against the target's Strength. On a success, you can move the target 5 feet closer to you. 

The spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
