@Mohrpheus Yes, that's what I meant. Parallel to her sword rather than in a straight line. In the first interpretation, the swords are tip-to-end in a straight line increasing the length of her attack. In the second, they are always parallel to her sword, so when swung horizontally, there is a blade on either side of hers, and when swung vertically, the three blades are essentially stacked.
