Or maybe it shapeshifts?? My mistake!
Weapon tally: Ruby’s, Pyrrha’s, and Nora’s shapeshift, and Weiss’ has different settings; Ruby’s, Pyrrha’s, Nora’s, and Ren’s shoot things; Weiss and Yang seem to have some inherent magic; Blake I think has that whip thing from a few episodes ago. This show really likes its weapons.
Know what the best weapon would be? Supersharp magical paper airplanes. You could throw them at angles like boomerangs, stab people with them, and make a really big one and fly around on it. Yeah.
