Infernal Rain

Before Superior Zombie could lunge, Altair disrupted the asphalt with Mold Earth, changing its properties from a solid to a liquid back to a solid so that its ankles were trapped. The Zombie tumbled over face first, hitting the earth with a solid thud, when the asphalt began to crack beneath its scrambling. 

Altair pointed a finger as Mana coalesced into a sphere, igniting into a great ball of fire so black it appeared like shadows dancing beneath the moon. The presence of the Vale was tangible, commanding authority like a king over its subjects. The ball of flames shrunk to the size of a marble compressed by the Authority of the Vale. 

'I wonder if it's possible to use heat convection to pull the heat of my surroundings into this flame? I ought to make a formula,' Altair thought, igniting the flame that blazed brighter than any sun; it pierced through the Zombie's brain, incinerating the head in the blink of an eye.
