Laura wins

Laura and Camilla sent spell after spell at each other. They deflected fireballs, ice spears, and other spells. The living room became a disaster area as furniture caught fire, and lamps were shattered.

The two battled for an hour and both were near exhaustion when Laura managed to get a immobilization spell past Camilla's defenses, and Camilla froze.

Laura put out the fires in the living room and walked up to the frozen Camilla. "Well, that was fun...not! But what to do with you?" She grabbed a lock of Camilla's hair and let it go. She walked are Camilla.

Camilla was frozen. She could move her eyes and breathe but nothing else. She was scared of what Laura would do.
