In the World of Warcraft game, there're two engineering specializations, both tied to a specific race. They're available to the characters who take up the engineering trade skill such as goblin and gnome.
   On the one hand, most of the players are side with the Alliance who wish to take up gnome engineering have the ability to do the quest without leaving Ironforge. An alliance engineer needs to visit the Tinkertown section of Ironforge and speak to Tinkmaster Overspark.
   On the other hand, Horde players who wish to pick up Gnome engineering must go to Booty Bay and speak to a gnome in one of the houses. Although the quest givers for Alliance and Horde different, the steps of the gnome engineering quest are the same for each faction. The first thing a player who wants to take up gnome engineering must do is to sign the pledge of secrecy and return it to the quest giver.
  Once a player signs and returns the pledge of secrecy to the quest giver, then he will give the player a "Manual of Engineering Discipline." The quest giver asks the perspective gnome engineer to read the manual, but it is not necessary to read the book to complete quest. The player can merely return the book to the same NPC to go onto the next part of the quest.
Both Alliance and Horde quest givers will ask a player who wants to learn gnome engineering to bring back examples of his work. The items required are an accurate scope, an advance target dummy and six mithril tubes.
When it comes to goblin engineering, a player wishes to take up the goblin engineering trade skill specialization, he must have at least a 200 skill in engineering and his character level must be 30 or higher. Likewise, the character must have been referred to one of a master engineer trainer to complete his skill level.
Both Horde and Alliance players want to be goblin engineers in World of Warcraft must head Gadgetzan in Tanaris. The goblin engineer will have to seek out and speck to Nixx Rocketspring who will give the character the goblin engineering quest.
Players want to make the accurate scopes themselves will need to buy the schematics, but it is easiest to head to an auction house in one of the capital cities and buy the items asked for. Once the items for the quest have been bought or made depending on the player's preference, the player must return the NPC who gave him the quest and hand the items over to the quest NPC.
Once the required items have been turned in, the quest giver will give the player a "Gnomish Engineering Guild" membership card which says it is good for two weeks. Should the player let the membership expire; the player can not learn new gnome engineering schematics.
Engineering is a flavor skill. Neither goblin nor gnome engineering will make a player rich, gnome engineers can make devices like the gnomish transporter can randomly change a players race, gnomish rocket boots sometimes explode, the gnomish harm prevention belt has a chance of randomly sending its user to another dimension.
With the pattern for the gnomish universal remote control, all engineers can make it. Either can this item charm a mechanical monster or boost its power with potentially harmful effects to the user. Gnome engineering is fun, but the items produced are of questionable reliability.
