Engineering Engineering is a primary crafting profession by which one can create many useful and amazing items as well as complete vendor trash . Engineers can craft items that , in general , all classes find helpful in PvE and PvP . However , most of the items crafted by engineers are only employable by engineers . Many of these items come with a chance for unexpected backfires , often with hilarious results . Hunters in particular see a lot of use from engineer - made guns and scope s . Twinks also find engineering useful because there is no level requirement to the gear that can be made . Engineering profession recipes are known as Schematics . Two of the more notable of these are : There are also several engineer - only enhancers to boots , gloves , belts , cloaks , and a well known parachute cloak enhancement . For the Alliance faction , Gnomes benefit from a + 15 racial bonus to their Engineering skill . Note that , unlike most professions , engineering is not exactly what you would call a money maker even when maxed , since most of the useful items that engineers create have an engineering requirement and thus there exists little to no market demand for them . Usually you will want to take engineering mostly for personal use with occasional sales to other players . Items like Mekgineer ' s Chopper give a very decent profit but feel lucky if you manage to sell one every week or two , other items with potential to be sold are the scopes for guns or bows and the engineering crafted pets like Lil ' Smoky and Lifelike Mechanical Toad . Before patch 4 . 0 . 1 removed them , craftable arrows and bullets were a decent source of income for engineers . Schematics . Schematics are learned mostly via trainers all over Azeroth and Outland . More recipes can be learned by schematics bought from vendors than in any other profession . Specialization . Engineering , like tailoring and blacksmithing , provides opportunity to specialize . At skill level 200 an engineer may specialize in Gnomish or Goblin Engineering . The primary differences between the two specializations in terms of craftable gear are the destinations of transporters and the abilities gained by wearing the trinkets . Some of the items require that the engineer have one or the other specialization in order to use them ; fortunately most are employable by both equally . Specialization recipe comparison . For more information , read the respective pages for Gnomish and Goblin Engineering . All in all , both Engineering disciplines are useful and fun . Some believe various Engineering gadgets , such as the or , are excellent for use in PvP given their crowd control potential and stamina boost . That being said , many people don ' t take Engineering until they reach max level and have ample gold saved because of the fairly steep expense involved in leveling it . Switching specializations . To do so , you must travel to the hut of Narain Soothfancy in the far north - eastern corner of Tanaris , just north of Steamwheedle Port . Read the book " Soothsaying for dummies " on the table in the hut and it will give you the option to unlearn your current specialization . The fee is 150 gold . Once you have lost your specialization you will need to speak with the specialization trainers in Gadgetzan for Goblin Engineering or Ironforge / Booty Bay for Gnomish . Some Notes : History in the World of Warcraft . Patch 2 . 1 . In Patch 2 . 1 . 0 came a major overhaul to the Engineering Profession to increase the usefulness of the profession . Among other changes , Blizzard created 11 Epic Helm Schematics , , and an Epic Gun - . These Schematics are available from faction Grand Master Engineering Trainers . Engineering skill 350 is not the only pre - requisite : Depending on your class you may craft some ( but not all ) of these goggles . For example a Paladin can make all 3 plate options but none of the cloth , leather or mail ones . However below is a listing of Epic Head items that can be created at 350 Engineering skill between the classes : With these adjustments , the Profession was reborn into an attractive alternative since all 11 helms are comparable to Tier 5 . These goggles can be equipped at level 62 . Patch 2 . 3 . Some notable changes in Patch 2 . 3 . 0 include : Source and full notes : http : / / www . wowwiki . com / Patch _ 2 . 3 # Professions Patch 2 . 4 . As of Patch 2 . 4 . 0 every epic helm schematic added in 2 . 1 may now benefit from upgrades . The engineering schematics drop from Sunwell Plateau trash mobs and do not BoP . Additionally all Patch 2 . 1 . 0 epic helm Schematics now require level 62 . The Schematics require 375 to learn . Below is a listing of the items that can be equipped with 350 Engineering skill at level 70 : Wrath of the Lich King . The big Engineering news in is obviously the motorcycles , the for the Alliance and the for the Horde . Despite their expensive materials , they are nonetheless popular . There are also many new devices for Engineers to tinker with . With the expansion there is a new set of engineering helmets . These helmets are item level 200 , equivalent to gear dropped in the 10 - man raids available with this expansion ' s release . Some items with higher ratings were available from 25 - man raids , and later content ( Ulduar , Trial of the Crusader , and Icecrown Citadel ) and items purchased with emblems provides gear that is greatly superior . There are new Engineer - only trinkets : There are also several devices which can be integrated into an engineer ' s own equipment , essentially being Engineer - only enchants : Note that these cannot be put onto items presented in a trade window . While they can be put on BoE items , they offer no benefit to non - engineers ( or Engineers who have not met the required skill level ) , so the market for them is limited . Also , many of these share cooldowns with other DPS burst abilities . Patches 3 . 1 . 0 and 3 . 2 . 0 expanded the list of enhancements available , and added more stats to them , to make them somewhat more competitive with enchantments , and with other skill - specific enhancements . With 4 . 0 . 1 engineer - only enchants have no longer stats , but can be used alongside with general enchants simultaneously . These all require 525 Engineering to make and use . Engineer mounts . Engineers are able to create Mount s for themselves and for others . They can create a ground mount and four Flying Mount s . An Engineer must reach 450 Engineering skill before they can learn the schematic for the Mekgineer ' s Chopper ( Alliance ) or the Mechano - hog ( Horde ) . The unique thing about these mounts is their ability to carry an additional passenger in the motorcycle ' s sidecar . There are no restrictions on the passenger ' s riding skill , so a player with their own bike can cart around lower level players who are without mounts . The Mekgineer ' s Chopper can only be made by the Alliance and the Mechano - hog by the Horde . Both need a Riding skill of 150 to be used , but they do not require engineering . They are BoE ( Bind on Equip ) , so they can be sold on the Auction House . The bikes require a number of costly vendor - only materials to produce , and because of this are reasonably expensive to purchase . Engineer s can create Flying Mount s as well . They are the Flying Machine Control , Turbo - Charged Flying Machine Control and the two specialization - bound Geosynchronous World Spinner and Depleted - Kyparium Rocket . These do not carry additional passengers . The Flying Machine Control and Turbo - Charged Flying Machine Control do , however require Engineering skill to use them ( 300 skill and 375 skill , respectively ) . They are not faction restricted , either , allowing Engineers on both sides to learn to make and learn to fly both mounts . They are also Bind on Equip and can be sold on the Auction House . The two mounts added in Mists of Pandaria are not restricted to your engineering skill , but the Geosynchronous World Spinner can only be made by Gnomish Engineering and the Depleted - Kyparium Rocket only by Goblin Engineering . Though they are BoE , Gnomish engineers can use the Depleted - Kyparium Rocket and vice versa . Engineering - exclusive crafted companions . Two engineer - crafted small pets , Lil ' Smoky and Pet Bombling , were bind on pickup and therefore exclusively learned by engineers . However the spells that they teach did not require engineering , so it is possible to retain use of the pets after dropping the profession . As of Patch 3 . 3 . 3 , they are no longer bind on pick up and can be traded like any pet . The recipes for these pets were also formerly specialty - specific - Lil ' Smoky for Gnomish Engineering and Pet Bombling for Goblin Engineering . However , both recipes are now obtainable by all engineers as loot in Gnomeregan . is dropped by several mechanical NPCs , including Arcane Nullifier X - 21 , Peacekeeper Security Suit and Crowd Pummeler 9 - 60 . drops from Mekgineer Thermaplug at a very high , perhaps 100 % , rate . Garrison . Players building their garrison s while on Draenor that have engineering should consider building a level 3 Barn ( for ) . The Barn is classified as a medium building . Choosing a second profession . By far the most complementary second primary profession is mining . The vast majority of the materials needed for Engineering recipes are acquired through mining . The leather found through skinning are also needed in a small number of schematics . Without a secondary skill that provides a character with a solid source of income or materials , such as mining , or another source of substantial income , the player may find it difficult to level his / her engineering skill . If you have a way of obtaining metals , such as an alt with the Mining profession ( such as a blacksmith ) or enough gold to buy metal at the auction house , then the jewelcrafting profession would be a good secondary profession . This is primarily because most engineering items only require skill in engineering and are not level dependent , and the engineering skill can be rapidly advanced by making blasting powder , dynamite , and bombs for personal use . Thus , low - level characters can equip themselves with powerful engineering gear , making leveling faster and easier . This also gives such engineers a distinct advantage in low level battlegrounds ( such as Warsong Gulch ) as they will be far better equipped than comparable non - engineers . Jewelcrafting can then be used with the same basic materials ( metals and stones ) to craft early rings , amulets , and trinkets - making the character with this combination even more powerful . In addition , jewelcrafting allows prospecting raw metals to produce gems , which are used quite extensively in engineering schematics . Draenei and blood elves have the advantage of starting in an area where both of these skills can be readily trained . Other races can make the trip to the necessary cities for jewelcrafting training without much risk and difficulty .
