Hakudo Technique - Elenia attempts to grab the target from behind and puts them into a sleeper hold using both her own and the target's own shadow to solidify the hold. Once in the hold, it is very difficult to break out and usually results in the target becoming unconscious.
Once the hold is in place, the hold last 1 round after which the hold is released.

Lower Tier - Minor Bruising around the neck and unconsciousness.

Equal Tier - Minor Bruising around neck and unconsciousness.

Higher Tier - Minor Bruising around neck and moderate stun. Basic actions only for next post.

I approve, but you don't need to have the one per thread usage. It's a fair technique; there's no auto hits and a sufficiently powerful foe could resist. So while this is fine for application now if you want to change the once per thread thing you can do that.

Ok, fixed. Now what, do i have to do a thread to learn it or do i now know it?

You need to do a training thread for it first. Once you have completed the requirements, you may have it. Check the link below to see how long the training itself needs to be.
