Yojimbo, Yojimbo, Yojimbo...
Why can't I heard anything besides this Greatness Zanmato.
I don't see him too useful. He's weak, no MP and very low HP even lower than my Valefor! He also don't have commad boost or shield, he don't have any normal command, Magus Sisters command is a lot more easier than him.
I never summoned him after I ruin the fun of battle with Dark Bahamut, thankfully, I still have data which Dark Bahamut is not Zanmato'ed. Anima Oblivion and Magus Sisters Delta Attack is more useful than one- hit-chop-head-move. Seriously, the game make mistake, they shouldn't have Zanmato, they should have Zantetsuken.
I did fine on Dark Aeons and Monster Arena without Yojimbo. Seriously, don't use Zanmato, I feel like cheating whenever I attempt to use it.
