But it's already shown in show that you can channel energy through your weapons to make a ranged slashing attack - Blake does it to Roman in No Brakes, she does it to the grimm in Mountain Glen, Raven does it to Neo when she jumps in to protect Yang, and Weiss does it to the White Knight in the White Trailer. Those are just the ones I can think of off the top of my head. The absorbtion of energy would be a semblance, as that's kind of what Yang does, but the energy attack with the glowing sword is just standard aura usage.
