A character who carries a sword will, at some point, drag the tip of the blade across a floor or wall. This is usually done to intimidate or to catch the attention of another character, or simply to invoke the coolness factor, but rarely does it have any practical application. It can also be associated with an Ax Crazy character or a Villainous Breakdown, because if someone holding a sword goes into a Primal Stance or becomes Limp and Livid, they tend to forget they're holding it and just let it drag. Or it might just be that they can't actually lift the sword for any length of time, either because they're tired or the sword is too big.
