[colour=royalblue]xxx[/colour] i have a musashi and there just like the other rares very hard to find even at level 50 but i guess its just luck im a skyly and this can make adifference on rares and stuff you find just try the harder difficulties and one will come along also animal parts like grass assasin arms+12 is about as powerfull as musashi so maybe a substitute is in order
:confused: hope i helped
