If we're talking characters I had a young Holy Knight who uses blade weaving. A form of magical projection that lets him form magic into a physical entity (still glowing), so he can patch up or reinforce his own weapons with it, or create floating blades that fly at foes, and other similar applications. For more I want to know how magic functions so I can expand more on how it works and make more advanced techniques.

But with how his magic is he can basically turn bladeless swords into lightsabers with his magic, which is cool. They just won't be straight laser lightsabers, just a magic blade.
