Apollo's Wrath

As your connection to all forms of nature has grown through rigorous training, you have earned the blessing of Apollo and can call upon the wrath of the sun when needed.

Upon casting this spell, you gain 10 magical arrows wreathed in flame. Each arrow sheds bright light in a 10ft radius and dim light in an extra 10ft radius. When arrow hits its target, it explodes into a fiery sphere that has a 20ft radius and forces every creature in the vicinity to make a Dexterity saving throw. On a failure, each creature takes 3d6 fire damage. On a success, the creature takes half damage. If the arrow hits a creature, the creature automatically fails their saving throw and also takes damage equal to a nonmagical arrow or bolt shot from the caster's weapon (Example being 1d8+Dexterity modifier if the caster used a longbow). These arrows ignore resistances to fire and treat immunity to fire as resistance. These arrows rest in the caster's quiver for one minute or until the caster loses concentration. 

Each arrow gains 1d6 of fire damage per level above 5th when this spell is casted at 6th level or higher.
