A bright flash of light flew from your fingers to a point you specified within the casting distance, and burst into flames with a low growl. Each creature within a 20-foot spherical area around the target point must make a Dexterity save. Those who fail the save will take 8d6 points of fire damage, and if the save succeeds, the damage is halved.

The burst of flame will spread around the corner. And ignite all combustible objects that are not worn or carried in the area. When using a 4th-level or higher spell slot to cast this spell, the damage of the spell slot you use is increased by 1d6 for each level higher than the 3rd-level spell slot.
