With the changes made to professions, Engineering is one of the few that provide any benefits to lowbie characters. The other possibility being Alchemy(a skill leveling guide will be provided for that in another thread). Engineering's benefits include being to craft/equip items and some nice consumables. At skill level 200, engineers can choose to specialize in Gnomish or Goblin Engineering. On with the guide! Firstly, the player should get a http://www.wowhead.com/item=40772/gnomish-army-knife or an http://www.wowhead.com/item=109253/ultimate-gnomish-army-knife. Both are usually available on the auction house for relatively inexpensive prices. Otherwise, you will need to create your own "tools". It is highly recommended that you get one of these Army knives to save on bag space and because of their shear convenience. Secondly, I recommend that you purchase/gather all the materials you need beforehand if you plan on "power leveling" your engineering skill up in one session. All of these mats can be kept in your bank, they no longer need to be kept in your character's bags. This will save you valuable time running back and forth trying locate more material. It is very important that when you reach the skill thresholds at 50-75 and 125-150 that you remember to learn you respective engineering skill. Whether it be Journeyman or Expert. Failing to do this may cause you to have to purchase/gather more materials. The material list.
