Upon being presented the scroll I bite my thumb,drawing blood.I then unravell the scroll and wipe my blood on it Signing the contract.I then re roll the scroll and upon focusing chakra to the mouth activate the scroll summoning several needles in my mouth which i spit out towards your clone with a intense amount of force behind them.I am 1 at your clones brain,Heart,Knee and elbow joints.For the reasons of heart,brain is a instant or extremely quick death.The joints although not vital if you hit them will restrict their movement by blocking of their nerves thus dis-allowing the brain to send nerves impulses to that part of the body telling them to move.I also aim at your kidneys and lungs for obvious reasons.
