Suiton: Kokusuineetsu no Jutsu - Water element: Blackwater Fever JutsuEdit
Prerequisite: Kirigakure no Sato Nin
This jutsu lets black polluted water burst from the ground and shoots it to the target. If the target gets touched by this water or he swallows some he gets sick. It starts with puking followed by slowing reflexes and ends with disorientation(this jutsu last 3 posts before the target gets better).
