"To an observer, it looks like a giant beam of light, but the attack's target point is only at the tip. It is the "ultimate slash" that cuts through everything in the "area" the light goes through. Its enormous power heats space around the tip, and as a result, it is interpreted as a wave of light that mows across the surface of the earth. One could also call it a directed energy weapon. Even if it is dodged, those in close proximity can still be temporarily distracted by its intensity."
Yes, light...
No, it accelerated Prana to a ridiculous level with her factor of the dragon and releases it as an energy slash that looks like a beam of light because it turns the surrouinding air into plasma due the heat

Even while blackened, Artoria's greatest power Excalibur is still potent. However, the sword is tainted an ominous black. Just as the fairies of the lake (Vivienne and Morgan) manifest as both good and evil, the holy sword has its own dark side. Still, its "character" as a holy sword is greatest. The function of converting the wielder's magical energy into light through the blade does not change, but the light is transformed into the same darkness of the blade.
The NP is the same, so, can you tell me how fast is a beam of darkness? (with the corruption we can confirm that is just mana)
