That makes sense, however typically when an item is upgradable you can ask rurik about it and he tells you what the other items and money you need are. In my case despite the weapons being in the inventory they are not mentionable in the smithy dialogue options. How am I supposed to find out what the items and money required are, or communicate to Rurik that I am interested in upgrading them? Are the options for glowfire, etc, disabled until a particular chapter or something like that?
