In the WLK classic server of "World of Warcraft", engineering is the most popular professional skill, because engineering has the highest benefits. How to upgrade engineering from level 1 to level 450? The following is the cheapest way to speed up.
In WLK, one of the main focuses of engineering is ammunition and ranged weapons. All Engineers are able to craft Saronite Arrowheads and Mammoth Hunting Bullets, as well as Ironclad Combat Shotguns and Nesingwe Pattern 4000. In Engineering, there are two classes - Gnome and Goblin - which allow you to craft Ice Peak Arrows and Shattering Shells at 450 respectively. Regardless of class, you can also craft an epic helmet such as Armored Titanium Goggles, Green Sight Goggles, Appearance Liquified Goggles, or Weakness Analysis Goggles.
In addition to equipment, engineering in WLK can also create a large number of useful items. For personal use, Blizzard added mechanical motorcycles and mechanical roadmasters to the aircraft and turbo-accelerated aircraft provided by TBC. These new ground mounts can be sold on AH. This category also includes two robotic companions that can greatly benefit the group: Kivis and the Pocket Mailbox. While the Pocket Box is just a mailbox (which is useful in itself), Keeves is a robot with repair capabilities. This makes him very helpful in dungeons or when searching for supply vendors and potential repair points.
Players who choose Engineering will often pair it with Mining as their gathering profession to gather materials needed for upgrades. Otherwise, the costs can become overwhelming as you get closer to the level cap. At each level, Engineers are also capable of salvage, which allows them to loot mechanical corpses for parts in a manner similar to skinning.
Like all classes, upgrade engineering is entirely possible while you generally pursue and upgrade your character. If you choose to mine, ore nodes will appear in the appropriate areas of the level, and the damage caused by the explosives will be proportional to the creature's health. Therefore, Old World and Outland trainers are listed below.
Ultimately, however, this is a guide that will cover the fastest, most cost-effective ways to get to 450. If you are training to enter Dalaran, you should find DiMurphy Oceank in Dalaran. Along with other Northrend trainers, he will be able to teach you all vanilla and TBC recipes. His proximity to AH is also invaluable for obtaining any additional materials you may need or selling something you create.
In patch 2.3, Blizzard has given all trainers in the Old World the ability to train Artisans, so it's your choice which city to start with, and if you're interested in specializing after reaching skill level 200 and 30, check out the section below and choose yours accordingly city.
When you pass through the Dark Portal, the Master Engineer Trainer will appear in the first area of your faction mission. For the Alliance, this means going to the Honor Keep and finding Lebsky. Sebig of Salma will do the same for the Horde. Unlike most other classes in TBC, Engineering's neutral trainer is in Netherstorm, not Shattrath. If you do both missions and upgrades, Sehirro in Area 52 will be your next stop. However, when you complete the main level, all players will need to visit Shattrath in order to purchase the Schematic: White Smoke Bomb from the Astral Merchant Laslay.
Just like in Outland, Northrend Master Trainers will be in each faction's starting area. In Warsong Keep, the Horde will need to speak to Chief Technician Livini, while in Dauntless Keep, the Alliance will need to find Thok Brightnail. Arriving at Dara, all engineers can then train with DiMurphy Oceank in the Magical Business District. Dalalan also has two dedicated trainers: Fendal Whistle of the dwarf and Didi the fitter of the goblin. Outside of the main city, all players can also find Binji Brightchain in the Argent Tournament.
In Vanilla Era, Blizzard created two branches of engineering specialization: gnomes and goblins. Gnomes were initially more focused on creating gizmos, while goblins emphasized volatile explosives. Over time, however, the importance of choosing a path has diminished, and in WLK the choice can actually be divided into whether you want to make shattering rounds with goblins or ice-edge arrows with gnomes.
To become a Gnomish Engineer, all players need to find Oglethorpe Obnotis and complete the work. The Goblin Engineering quest chain begins with Nyx Spookspin and ends with another version of the work.
In 3.2, Blizzard also added the option for any professional Engineer to visit Narian in the Steamwheedle Port of Tanaris and pay 150 gold to switch their choice.

285 – 300: Thorium Bullets
Use Thorium Bars to craft Thorium Bullets.
300 – 310: Magic Iron Screw
Convert magic iron ingots into magic iron screws.
310 – 320: Magic Iron Shell
Use magic iron ingots to craft magic iron casings.
During this time, you must also craft Elemental Explosive Powder.
Created by combining fire particles and earth particles.
Between 320 and 325 you have another option. If you have an excess of bolts and casings, a magic iron rifle is probably the best choice. However, you must purchase heavy tree trunks from a trade supply supplier. If you have extra Explosive Dust, Magic Iron Bombs may be a better choice, but be careful as you'll still need more later. This is also where you buy the Schematic: White Smoke Bomb from the Astral Merchant Lares in the Lower City.
320 – 325: Iron Bomb
Combine magic iron screws, magic iron shells and elemental explosive powder to create magic iron bombs.
or
320 – 325: Fel Iron Rifle

After you complete Smokescreen, you can go to Northrend and become a Master Engineer.
350 – 370: Cobalt Screws
Use Cobalt Ingots to craft Cobalt Screws.
Northrend offers more options on how to level up your engineering. Your first one is between 370 and 385, which may seem obvious but requires careful consideration. If you choose to craft only the Subtle Explosion Trigger and Overload Capacitor, it is possible to require fewer ingots than crafting the Hammerhead Hoe, but the Capacitor recipe turns green at a lower level than the Hoe. So, if you don't use a hammer hoe, you may end up using more spindles than you originally chose to use.
370 – 377: Subtle Explosive Trigger
Use Cobalt Bars and Water Crystals to craft the Subtle Explosion Trigger.
378 – 385: Overload capacitor
Use Cobalt Ingots and Earth Crystals to craft Overload Capacitors.
or
370 – 375: Subtle Explosive Trigger
Use Cobalt Bars and Water Crystals to craft the Subtle Explosion Trigger.

Converts Cobalt Ingots into Hammerhead Hoes.
385 – 390: Explosive Bait
Use the Subtle Explosion Trigger and Frostweave Cloth to craft explosive bait.
390 – 400: Frost Steel Pipe
Mix cobalt ingots and water crystals to make frost steel pipes.
400 – 405: Diamond Refractor Scope
Make a diamond refractor sight using cobalt screws and frosted steel tubing.
405 – 410: Box of bombs
Combine the Subtle Explosion Trigger and Saronite Bars to create a box of bombs.
410 – 415: Mammoth Hunting Bullets
Combine the Subtle Explosive Trigger and Saronite Bars to craft Mammoth Hunting Bullets.
415 – 425: Saronite Arrowheads
Convert saronite ingots into saronite arrowheads.
425 – 430: Mechanical Snow Goggles
Combine saronite ingots, northern turf, and eternal shadows to craft mechanized snow goggles.
430 – 435: Noise Machine
Use cobalt screws, frost steel pipes and overloaded capacitors to build a noise machine.
435 – 448: Dwarf Saber
Combine a Saronite Bar, Skinning Knife, Blacksmith's Hammer and Miner's Pick to craft a Gnomish Saber.
The map turns green in his steps, so you have to do more than 13. The 25x recommended in the materials list is safe, but as you get closer to 448, buy in small piles from a trade supply supplier so you don't buy too much extra.
The next two steps are the only pre-450 recipes in WLK that will remain orange until you reach the apex, so even if you are able to craft them earlier, it's best to save them for the last 2 levels.
448 – 449: Wormhole Generator: Northrend
Crafted by combining Titan Iron Ingot, Eternal Shadow, Eternal Water, Eternal Fire and Eternal Air.
In your final level you will craft your epic engineering helmet. All options are listed below, requiring different combinations of Eternal Elements and Rare Gems. These can be purchased, mined or transformed by the Alchemist. The only constant materials between these pieces are Titan Iron Bars, Thick Northern Leather and Frozen Orbs, all of which are described in the materials list, and the remaining materials are up to you.
449 – 450: Any epic helmet
Armored Titanium Goggles, Charged Titanium Goggles, Electromagnetic Fusion Vision Enhancer, Green Sight Goggles, True Vision Ice and Snow Eyepatch, Solid Healing Amplifier, Appearance Liquefaction Goggles, Weakness Analysis Eyes.
In the end game, Engineering crafts BiS ammunition and scopes as well as pre-raid BiS ranged weapons. All Engineers are able to create the Heartseeking Scope and Ironclad Combat Shotgun and the Nessingwe 4000. Ice Peak Arrows are only available to Gnome Engineers and can be learned from Fendal Whistle in Dalaran; Fragmentation Shells are crafted by Goblin Engineers and learned from Tidy the Fingersmith.
In addition to this, engineers can create two new motorcycle ground mounts. Each recipe can be purchased after reaching Exalted with your faction's Northrend contingent. To obtain Schema: Mechanic Roadhog, players need to be exalted through the Horde Advance Army, and to learn Schema: Mechanic's Motorcycle, players need to be exalted through the Alliance Advance Army. All engineers also have the opportunity to study Structural Drawing: Kiwis. This recipe has the highest chance of killing mechs in Ulduar, but it can also be found on other mechs in Northrend. Kivis is extremely useful when completing dungeons, raids, or any type of extended farming, making it a very valuable part of any engineer's toolkit.
