Augusta was delighted the fireball seemed moderately effective against these creatures.  Though she had not expected Octavia to take a slash from a creature.  "Octavia!" She screamed as she heard the demon dog yipe, though she was quick to quiet as she saw the beast heal.  Her eyes widened slightly at the sight and it dawned on her even more that this was another world from Earth.  She clenched her teeth in anger and stepped forward.

She has figured out how to make a bolt of magical energy... And then, a bolt of fire... Now, maybe, she could spew fire out of her hand.  She stood over the wretch that Octavia pulled down and pointed her hand out.  If a bolt was gathering energy and firing it at once, maybe she could do the same thing but let it freely escape her hand.  Just use the same mechanics she had used earlier to make it spew fire and aim it right at the head and shoulders of this wretch that was held down.
