Namine tilted her head in thought for a moment, then furrowed her brow in concentration. In her mind's eye she focused on the image of a ball of flame shooting towards (and hitting) a nearby wooden box. The box wasn't close enough for them to be in danger if it did catch fire, but it made a good, nonliving target.

Once she had the image firmly in her mind, Namine raised her hand and spoke. "Fire!"

A small ball of flame arced from her the box, not catching it on fire but at least charring a portion of it respectably.
