A sun slowly lit up between Leon's palms.
This wasn't any spell that Leon had cast before. Nor was it some sort of magic-infused item. It was a concentration of pure heat and light!
Leon had abandoned all the external forms of spells and instead concentrated all of the core of his fire powers. He manifested them using the powers of planar laws, causing Blazing Light, the purest form of power, to appear.
It didn't have the mixed physical and fire damage of the Magma Fireball, or the terrifying flame shockwave of the Explosive Fireball, and especially not the amazing radius of the Scarlet Firestorm. But having abandoned all of this, what was left to the Blazing Light was intensely concentrated light and... heat.
It was just a ray of light!
Its attack radius was not wide. Concentrated within Leon's palms, it was only as large as an egg and its external form was like a thicker Scalding Ray.
