You create a magical flaming orb that floats over your head. The orb sheds bright light in a 60-foot radius and dim light for an additional 60 feet. The orb has three charges. When a creature you can see within range takes damage, you can use your reaction to expend one of the charges and hurl a magical flame from the orb toward that target. Flames envelop the target, reducing the damage it takes by 1d4 + your spellcasting ability modifier. The creature that dealt the damage to the target must succeed on a Dexterity saving throw or take fire damage equal to 1d4 + your spellcasting ability modifier. The radius of light emitted by the orb then decreases by 10 feet. When you expend the last charge, the spell ends.
