Myself and another ninja were spamming Hojo Ichi/Ni on Kaggen and could not land it. I can't speak for the other guy but my ninjutsu is of course capped.

But yeah, I knew about relic hands' exp magian trial^^. Thanks for the reply though. I just feel like Futae is a bit silly when it could be really useful since ninjas are fairly limited in M.Acc gear, unless you're just so absurdly dedicated to the job and fill your bags with every situational piece ever.
