"Condense! Blaze!"

Cecilia's crisp voice emitted a peculiar magic within the camp. 

Although her voice wasn't particularly loud, it completely drowned out the clashing of steel between Sean and the two Dogheads Guard Captains, as if the world fell utterly silent for that moment, with only Cecilia's voice remaining.

Sean wasn't particularly knowledgeable about magic, but the final sequence of syllables Cecilia had just chanted was clear to him: "Condense" and "Blaze." 

Given these words and Cecilia's consistent performance, Sean immediately knew what kind of magic she was using.

Flame Arrow!

Among the few magic spells Cecilia had mastered, this was considered one of the more advanced ones. 

Unlike spells like Lesser Fireball, which had obvious area damage, Flame Arrow was a magic that required the mage to mentally lock onto the target and control it.
