okay. Well there is only one other snake left. Manda, the snake king. However, I will neither summon him, nor teach you to do so as he would likely just try to eat us both. (Boss summons can only be summoned by cannon characters. So only Sasuke or Orochimaru can summon Manda)
But that's not all I have to teach you. There are also 2 jutsu affiliated with snakes. They are
(Senei Jashu) - Hidden Shadow Snake Hands
Rank: C
Type:Supplementary
Range:Short-Mid
Chakra Cost:15
Damage Points:N/A
Description: Senei Jashu is a Ninjutsu technique that manifests a snake, which extends from the sleeve. The ninja can extend these snakes to attack a target. Once extended the snake can bite into the target to hold and bind them.
Note: Must be able to summon snakes
and
(Senei Ta Jashu) - Multiple Hidden Shadow Snake Hands
Rank:B
Type:Supplementary
Range:Short-Mid
Chakra Cost:20
Damage Points:N/A
Description: Senei Jashu is a Ninjutsu technique that manifests a torrent of snakes, which extend from the sleeve. The ninja can extend these snakes to attack a target. Once extended the snake can bite into the target to hold and bind them.
Note:Must be able to summon snakes.
to start, I want you to extend your arm and focus your chakra much the same as if you were doing a summoning. Try to make a snake appear out of your sleeve and bind/bite my clone.
*Makes a clone*
Note that this jutsu doesn't need handsigns and also is not considered as a summoning.
