I've been meaning to try AF as my next main, and the skill Poison Tai sounds pretty good. What is taijutsu damage exactly and could someone tell me what are the ninjas the cause it most?

My starred and cultivated ninjas are: Suigetsu, Zabuza (reg and mist), Kankuro (reg + gnw), Kakashi, Hinata, Guy, Lee, Sasuke, Naruto, Sakura, Chiyo, Kabuto, Karin, Kurenai, Itachi, Asuma, Kimimaro, and the rest I don't really use.

TY
