witch saber are you talking about the new double bladed one isn't a jinzu and you get that schem by doing the ig88 instance. the jinzu is a single blade by killing the hand in rustess. then you have the the other ones that you are able to make when you reach a certian lvl. what lvl are you and witch one are you asking about. you will need a crafting station for it and if you had some besbin port that would be good as well, plus a ent buff is another plus. for the actual rescourses i couldn't tell you witch one is best and where to get them.
