She'll ignore that comment and keep her concentration on the spell. Within a short moment a small fire appears above her and as she continues casting it grows in size. The ball continues to grow until it's nearly nine feet in diameter. The exertion is rather visible on her face as her brow furrows from concentration and small beads of sweat trail down her face. Then with a short cry she releases the ball of fire sending it flying into the wall.

BOOOOOOOOOM.

The structure of the building shakes for a moment from the impact. And Fiona collapses to her knees from the effort. She'll try standing again after being still for sometime, much of her weight on her staff. "Not good enough." She'll curse to herself.

Still she manages a small smirk when she finally faces him. "You could say that." She'll say through heaves of breath.
