LEVELING NPC GUILDS
The Elder Scrolls Online includes a number of in game NPC guilds that players can join. These include the Fighter's Guild, the Mages Guild, the Undaunted, The Psijic Order, The Dark Brotherhood and The Thieves Guild. Each guild provides players with a full questline and skill line.
If you only have the base game there are 3 NPC guilds you can join:
Fighter's guild
Mage's Guild
Undaunted
If you have additional chapters and DLCs you can also join:
The Psijic Order (Summerset chapter)
The Dark Brotherhood (Dark Brotherhood DLC)
The Thieves Guild (Thieves Guild DLC)
Each of the factions starting zones will give you access to all 3 of the main guilds. Davon's Watch in Stonefalls, Vulkhal Guard in Auridon, and Daggerfall in Glenumbra. You can also find these guilds in the major DLC zones such as Summerset and Western Skyrim.
While each of these guilds have a rich and unique storyline associated with them, you are not required to do them in order to join the guilds and reap the benefits of their skill lines. Their unique skill lines include both active and passive skills. To get access to the full line of skills you will need to level each guild. Methods for leveling will vary from guild to guild and some are definitely easier than others.
FIGHTER'S GUILD
To level up your Fighter's guild you will need to defeat certain types of enemies or conquer dolmens. Vampires, werewolves, undead, and Daedra are going to be your primary source of points, and these enemies can be found in many places throughout Tamriel. Some of our favorite locations to power level are Alik'r Desert dolmens, Banished Cells group dungeons, Crypt of Hearts group dungeons, and the Vaults of Madness group dungeon as these particular locations are filled with undead and Daedra. You will receive 1 point per enemy defeated, and 20 points for each dolmen conquered. Since Dolmens are such a rich source of points, you will see that some zones players advertise “Dolmen groups” in chat. The most popular place for this is Alik’r. By grouping up you will receive all points from kills made by your group members as well as your own, so if one of you can get a hit in you’ll get credit. Another way to level this skill line is to visit Cardea Gallus at the Fighter's guild for a daily quest that will ask you to complete 3 dolmens in a particular zone. Completing this daily will award you 10 points.
MAGE'S GUILD
To level the Mages guild there are special lore books scattered throughout the world. [insert book image and map pins image]. Each book will provide 5 points when collected. It’s good to note that in a particular area there are 4 copies of the same book, which gives you options. Once you collect 1 of them the other copies will disappear. If you are on PC we recommend using the map pins addon which will show you the location of all lore books. This will make collecting the books much easier. Just like the Fighter's Guild you can also visit the Mages Guild for a daily quest. Alvur Baren will send you to a specific public dungeon to retrieve an item for him.
UNDAUNTED
Undaunted is leveled by completing group dungeon quests, pledges, delve dailies and trial quests. Completing the initial dungeon quest will award 25 points, completing a trial quest on normal difficulty will award 50 points and completing a trial quest on veteran difficulty will award 100 points. Once you hit level 45 you will receive an invitation to join the Undaunted which will allow you to unlock 3 daily pledge quests. Completing pledges on normal difficulty will award 25 points each, pledges completed on veteran difficulty will award 50 points each and pledges completed on veteran hard mode difficulty will award 100 points each. The Undaunted also has a daily quest available at any Undaunted Enclave for an additional 10 points. Bolgrul of the Undaunted will send you to complete a quest in a specific zone delve.
HOT TIP: For any of the 3 guild dailies, while the character you are on can only obtain 1 of each daily, friends may receive a different daily quest and can share them with you for even more points.
THE PSIJIC ORDER
If you have access to the Summerset chapter you can join the Psijic Order by first completing Summerset's first main quest, titled "The Queen's Decree". Once you've made your way to Artaeum, find Loremaster Celarus inside the Ceporah Tower. The Psijic Order is one of the most tedious to level as you will follow the questline which brings you to the far reaches of Tamriel. If you don’t have many wayshrines open yet, get your running shoes on! If you are on PC we recommend using the map pins addon which will show you the locations of all the time breaches making it a bit easier to navigate.
THIEVES GUILD
If you have access to the Thieves guild DLC you can join the Thieves Guild which is started by talking to Quen in any Outlaw's Refuge or by going into the Crown Store and obtaining the free quest starter. The fastest way to level Thieves guild is to steal! We recommend heading to the Belkarth Docks in Craglorn and looting all the containers which will net you a ton of stolen items to sell to a fence. Another great option is to go to Khennarthi’s Roost and turn the fields of sheep into veal. Selling and laundering the meat will get you a ton of points. Note that there is a daily limit to how much you can sell/launder which can increase as you level the skill line. You can also complete 3 daily quests for additional points including heists, the tip board and the reacquisition board.
DARK BROTHERHOOD
If you have access to the Dark Brotherhood DLC you can join the Dark Brotherhood which you can start by talking to Amelie Crowe in any Outlaw’s Refuge or by going into the Crown Store and obtaining the free quest starter. The Dark Brotherhood skill line is leveled by completing the main story quest as well as a variety of Dark Brotherhood daily quests including Black Sacraments and Marked for Death.
