Shadow Shuriken
-Used to hide an attack within an attack, this allows the enemy to think they dodged the attack and then be hit by the second one.

Temporary Body Paralysis
-It's used to bind for allowing an opening for your next turn.
-I'm not sure how it works, the closest I could find was that its strength is dependent on the user's chakra and it's similar to a physical restraint.
-Strengths: Creates opening.
Weaknesses: Not the best binding technique.
