I saw this thread i General disucussions.I tested it vs immortal teams and it is right. Minato and Masked man get poison from Poison TAI EVEN when they dodge a standard taijutsu attack.So yeah fix it.
To tell the truth in poison tai description is not written anywhere that the tai attack has to land to deliver the poison, just says that you need to 'use' tai attacks to spread it. ok, i know it doesn't make much sense but is actually so.
