Seriously though, legacy enchantments are serious business.  When Serge mentioned that he didn’t get rid of his Cross-issue handguns because they were “his guns,” this is partly what he was talking about.  His Phantom Shot (where he can fire without having anything loaded into it) is a technique that builds off of a legacy enchantment, since he’s had his twin handguns and Lucky Seven since he was about twelve.  If he got new guns, he’d have to start all over on that.
