I'm a new player (lvl 20 archer)and i've been playing for about 3 days. i see a lot of players running around with gems in their weapons and stuff floating off of them. im guessing that they crafted the items or the items were crafted and they bought them. is there a post that tells you everything you need to know about crafting, or can someone tell me the basics to crafting, like

where to craft

what to craft

what character to craft for

what gems mean

and so on.
