A ball of liquid flame, white and Orange with magical hunger is conjured in your hands. You direct it to a place you can see and then it blossoms with a low roar into an explosion of white hot flame. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw.A creature takes 2d6 fire damage and 2d6 radiant damage on a failed save, or half as much damage on a successful one.

The fire spreads around corners. It ignites flammable objects in the area that aren't being worn or carried.

 For the next minute, any creature that failed it’s throw can repeat the saving throw and resist the flame, ending its effect, on a fail they take 1d6 fire damage and 1d6 radiant damage as the Wizard’s fire continues to burn and eat away at them. 

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the fire damage or the radiant damage (your choice) increases by 1d6 for each slot level above 5th.
