The active abilities and the ultimate ability in the Fighters Guild skill line all focus on dealing damage to Undead and Daedric enemies as well as dealing AoE damage and providing group utility. The Fighters Guild is ideal for classes who fight in melee range as well as classes who plan on fighting a great deal of Undead and Daedric enemies. For the Nightblade, this will generally mean the Fighters Guild, but the Mages Guild has some solid options as well. However, since each guild grants players with unique skill lines with both active and passive abilities to choose from, it may be best for Nightblades to focus on one or two guilds in order to have the best skills available. Players will be able to join multiple guilds at once. More guilds will be added to the game in later updates. These four guilds are the Mages Guild, the Fighters Guild, the Werewolves Guild and the Vampires Guild.

Like all of the four classes in Elder Scrolls Online, Nightblades will be able to choose from four faction-based guilds.
