question about attribute points of ninja

hey everyone
i've been reincarnated to water nin nin
and want to know the right attribute points that allow me to wear lvl120 or higher katana , and put the rest in health points

Just put the mouse on lvl 120 katakana, it's written there how many attribution points u shld have to wear , its 275 or 257 if not epic , if epic just 36 , so put 280 points then wear ur kats an reallot then put all ur points in hp but make sure not to take off ur katana cuz u will have to reallot to wear it again.
