To help you with your crafting, there are NPCs called Artisans. To use a new artisan you must complete a quest to unlock their talents. In addition to crafting, artisans buy and sell items as well. You can train artisans by giving them materials salvaged from items by using an item you recieve in the main quest. Higher-level items are salvaged into higher-level materials. These crafters of fine magical items and effects will help you make brand new armor and weapons, add powerful enhancements to your existing armor and weapons, or carve additional gem sockets into your gear.
The Blacksmith can repair items and add gem sockets to items (even if they are rare or legendary).
The mystic creates scrolls, potions, magical weapons, spell runes, and charms, and can also enchant items.
The jeweler crafts gems , amulets, and rings. The jeweler can also remove gems from socketed items and can combine gems to improve their quality.
Each of your artisans only has limited know-how initially, but with the investment of some gold, crafting materials, and Pages of Training looted on your adventure, you can improve their skills to gain access to more (and more powerful) recipes. A few recipes can be found on the corpses of monsters or in eerie ruins as well, but your artisan may need to attain greater skills before they can be learned. Artisans also don't work for free. Crafting some of the most fearsome items and enhancements Sanctuary has ever seen doesn't come cheap: the better the item or enhancement, the rarer the components you'll need, and the more expensive it will be to achieve the finished product. That means it will pay great dividends to ensure that you have a steady stream of gold and salvaged materials flowing into your stash so you can reap the benefits of your artisans' ever increasing potential.
