Four Symbol Seal
A long chain of hand signs, charged all the way: a tailed beast within 100 blocks at 15% health or less has its health locked. Right click the player who'll hold it: the beast and the host are held fast as a stream of red chakra pours from one into the other, and the seal fills only while you keep the host in your sights. At 100% the beast is sealed and the host becomes its jinchuriki. If the host or you die first, it fails. Either way, half an hour before it can be done again.
