How does crafting work here?

So I’ve recently (and finally) gotten into this game after spending the majority of my life fawning over NWN2, and I’m having a hard time adjusting to the major differences, like the lousy resolution, small window, and the different inventory manager.

Right now, I wanna know how different crafting is here. I already got to the Shining Arms place and met the blacksmith, so we can go from there.

And I know crafting was never essential, but I liked bothering with it in 2 and saving up materials I would need later.

Speaking of, I remember how in 2, some gems weren’t materials and were only for selling unless in the SoZ campaign. I’d like to know which gems would those be here.

Manok shgould give you a book wich lists all the components needed for crafting.
