Not at all really sure what's going on with crafting. I understand the general idea, but have a couple questions. (1) If I didn't take a crafting skill, should I bother with all the reagents, metals, and just general crafting stuff littered about? Is it just junk? Or can I craft things without having taken any skill? (2) Do the crafting recipes I find from bookshelves persist from game to game? Or do I have to find them again when I make a new character?
