Rising Wave, as a foundational move, isn't simple because of its sword technique.

It is a beginning.

All the sword techniques of the "Six Forms of Ice" derive from Rising Wave. With this initial move, the surrounding energy is already disturbed by the sword's momentum, but because the spiritual energy unleashed by the sword tip is invisible, one might mistakenly think nothing has changed.

It's like a pebble falling into a lake; it seems to disappear without a trace, but the calm of the water's surface has already been broken.
