Cedric's Blazing Mane

You cause a volatile burst of flame to erupt from within you, forcing any creatures of your choice within 15 feet of you to make a Strength saving throw. On a failed save, a creature takes 4d10 fire damage and is knocked 10 feet back. On a successful save, a creature takes half damage and isn’t knocked back.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d10 for each slot level above 3rd.
