Like Ezio said, it's biggest asset is it's biggest weakness. Since the technique doesn't state the specifics of the technique, it is up to use to define those. We could in theory make the wave as large/small as we like, etc, but under the same principle, the opponent can argue that since the technique doesn't specifically state that, it doesn't happen. It gets in to a really grey area.@ Bold - Very true, but you won't ever see that in 'serious' battle. Not without techniques anyway.
And yes, the description is delightfully generic. It basically leaves everything up to the user.
Can you use this to your advantage? How/Why not?
xdVery true. Tai and Kenjutsu share a sentiment of realism, if so to speak. Where Ninjutsu largely revolves around rank and damage, there's a deeper 'feel' to Close Quarter Combat (CQC).
So you've got to, as you said, be realistic with how you describe your use of this technique, but don't let that stop you from being creative.
Your turn, boys; can you see yourselves using this technique in different ways? And for Omnom specifically; how could you use the Chidori Katana in different ways?
You know me too well, ZK. I will be very happy to be able to use Chidori Katana. Specifically for the numbing part of the technique. Create a sword using Dead Bone Pulse, swing it at the opponent. When they go to block, charge the bone with Chidori Katana, and slice straight through their defense.. Oh the fun I could have.
On other occasions, I have used a bone whip, and when the opponent blocks it, shock them. This would augment that strategy immensely. God I love Kaguya. xd
One question though: What's the difference between this technique and simply using Nagashi and channeling it down the sword?
