Probably monk at level xx, and finish HW story, talk to npc to unlock the class, just like HW class

I just really want they make Samurai armors i love the way the Samurai looks in FFXI
They seem going with common samurai style like from manga kenshin or gintoki from gintama instead of going full armor back in the day where samurai is still the major player in the army, though iam not surprised to see 1 or 2 shogun armor set
