Yeah, the crafting is pretty amazing and complex. It's hard not to want to focus on all the disciplines. For example, I noticed a few of my pieces of gear were pretty low, so today I crafted a new sword, shield, belt, and boots. Now the first step to becoming a decent crafter is to research. You unlock traits by researching item with those traits. It destroys the item, but then you can craft stuff with those traits as long as you have a precious gem. I've got a few traits researched for most armor and weapons at this point. The traits vary between giving magicka, stamina, health, speed, critical and durability boosts. There are a lot.
So I make a sword with a decent trait, and then I use a honing stone to increase it's damage, which turns it into a green item. I can actually improve it all the way to an epic weapon if I have the improvement materials, but at this point I'm happy with it being green. Then I go to the enchantment table. I've got a lot of runes translated at this point, and I can make glyphs at a decent level, so I whip up a frost damage weapon glyph and apply it to my sword. Viola, I have a fancy magic sword. Oh, I almost forgot, you can unlock all sorts of racial motifs that decide what your sword looks like. So I really enjoy the breton style heavy armor, and the redguard swords. There are 10 different styles to craft as.
