@Maki It must've been low level Dust sorcery because Weiss actually used Myrtenaster to draw a circle in the air, then held Myrtenaster pointing at the circle, and the circle became a shield with cyan shockwaves when the White Fang Lieutenant struck it. It was the same kind of shield with cyan shockwaves that Neo produced from her umbrella, which has a hole in the top of the shaft, possibly for expelling Dust.
