Keith laughs as the burning goo hits him not attempting to dodge something that feels like jello to him he laughs as he starts charging Forrons magic. " hahahahahahaha is that all the heat you can muster?...if so then I'll show you a flame done right." He moves his arms Swiftly his opponent next to useless against Forron.

He finishes the ritual and calls out the spells name." Supernova!" Fortunately he doesn't explode. But the whole room swiftly begins to fill with fire hotter than thermite persisting as long as Keith can hold the attack the room roils an heats up burning away at jhedges that regrow as the inside of the boundaries burn like the inside of the sun. After about fifteen seconds  he relents dropping his arms.
