As he resumed a more relaxed stance, I willed the claws to disappear, and they vanished in a manner similar to the whip. "This weapon is capable of extending and retracting quite easily. Even if damaged, it barely costs anything to replace them, and despite their current size, when I put more of my magic energy into them, I can make them grow in size. I can even separate parts of the claws to serve as restraints able to seal away a person's magical energy." I left out how it was weak against fire, and that currently the time it takes to decrease or increase the weapon's size is still slow. However, with proper training, I can make it change size just as fast as it takes to materialize something like a black key.
