To get certified in the base game crafting professions you will need to go to the starter city for your faction and find the master crafters, Millenith in the fighters guild and Danel Tellano in the mages guild.
Each crafter will give you three missions which you will need to complete one at a time. Each mission will certify you in one of the crafts, and once you have completed all six missions you will be able to do daily writs from the boards found in any major city.
For jewelry crafting you will need to find Felarian near the crafting area in Alinor in Summerset.
Materials used in crafting can be found in several ways. Resource nodes scattered throughout the world will provide raw materials like ores, plant fibers, logs, alchemy plants and rune stones. You can get other materials from killing enemies or animals in the world or from looting containers you find in dungeons or the overworld. Keep in mind that some containers are owned by NPCs and if you are caught stealing from them you could wind up face to face with a guard.
Alternatively, you can buy most crafting materials from guild traders around the world, though the prices vary from trader to trader and can be rather expensive depending on the rarity and quality of the material.
Trait materials can be occasionally dropped from resource nodes when you are mining for resources, but more often you will get them when you refine the raw materials at a station. More in depth information can be found on each material and trait in the advanced crafting guide.
You will notice that many weapons and armor pieces in ESO have a “trait” listed in the description. This trait gives the item a bonus effect, and is active at all times as long as the piece is not broken. Having the right trait on an item can be very beneficial as you progress in the game, and will be immensely important as you progress towards late game content like vet dungeons and trials. This is where research and transmutation stones come in.
Transmutation stones are little purple stones you will pick up in game as you complete the daily random dungeon (10 for the first random dungeon of the day, 1 for subsequent random dungeons), Undaunted Pledges and Rewards of the Worthy from PvP sources (Battlegrounds and actions in Cyrodiil and Imperial City). These will allow you to change the trait on any item you wish, so long as you have researched the trait yourself. These stones are non-transferrable, meaning you cannot give them to another player and have them transmute an item for you. You can only have 500 of these on you at a time(1000 with ESO+) and it costs 50 stones to transmute one item.
Researching items allows you to learn the trait for a given item, and it takes real world time to research. The research timer is active even when you are offline, and as you unlock more traits on an item the amount of time to research the next trait grows. The first trait on an item takes about 6 hours to complete and by the time you get to the ninth trait it can take as long as 64 days. There are passive skills in each crafting skill line that will reduce the time each trait takes, but even with all the passives unlocked it still takes about 30 days to complete the last trait. To start off you will only be able to research 1 item at a time, but there is another passive that will allow you to research up to 3 items at once for each craft.
The research timer is on a per item basis, so if you have 4 traits complete on light legs in the clothing station, the next trait on that item will take up to 2 real world days to complete. But, if you have not researched anything on the light head piece, that one will still be around 6 hours to complete.
LEVELING YOUR PROFESSIONS
Experience for crafting is called “Inspiration” and it is earned when you craft or deconstruct an item. You get more inspiration from deconstructing than anything else for blacksmithing, enchanting, clothing, woodworking and jewelry crafting. For alchemy and provisioning you get most of your inspiration from making items. As you level each craft, you will be able to invest more skill points in it and unlock the ability to craft better items and get more resources from deconstructing and refining.
Your crafting levels are independent of the level your character is, so you could have a level 45 character but only level 1 blacksmithing. The crafting level also influences the types of resource nodes you find in the world. Let’s say your character is at CP160, the max level for gear, but your wood working is only at level 4. When you come across a log in the world, it could be either the CP160 material (Rough Ruby Ash) or the material you can make at woodworking level 4 (Rough Hickory). This system allows you a chance to pick up materials for your current player level as well as a chance to pick up materials you can actually craft with.
