Cult of the Zenith
All Draenor-grade professions but for archaeology, fishing, first aid, and cooking have prerequisite items and quests that you will need to perform in order to begin learning the Draenor-specific recipes for that craft.
First Aid, Fishing, and Cooking
Engineering gives a great number of benefits, such as personal “enchantments” which boost your speed, damage, and utility. Nitro Boosts give you a “sprint” like ability or Invisibility Field gives a short “invisibility” ability for belt “enchantments”, or the Goblin Glider that gives you a mobility-enhanced parachute as a cloak “enchant”.
Engineers can also easily make a variety of items to increase personal utility for their team. Take, for example, the Stealthman 54, which allows any class to enter a shadowmeld-like stealth while they remain stationary, and for six seconds after, or the Shieldtronic Shield which gives a small damage-soaking bubble on the healing potion cooldown.
To level engineering, you will need a regular supply of mining materials, so it is recommended that you level mining with engineering.
