Under each different discipline in Tome of Battle there is a list of associated weapons. Are these weapons flavour-based, or do you actually need a weapon on the list to use stances and maneuvers of that discipline?
More info: I am building a warblade and I am interested in using the Diamond Mind and the White Raven disciplines. The disciplines' weapon lists do not share a common weapon. Will I need to change between greatsword and bastard sword in order to use the different disciplines?
