Cooking is a secondary crafting profession, which is available in addition to your two main professions. It takes various food crafting materials such as meats and fish and turn them into consumable food. The consumables give statbuffs and are used by raiders and other players seeking to maximize performance. It is a great money maker and you should have it on your main.
Before anyone asks - yes there are archived copies of old addon versions both on our github repository and on several of the addon sites we use, and these will continue to be available after Cataclysm comes out, so you'll be able to get those old files if you really want them. I'm not going to bother making these more easily accessible unless you give me a very good reason. "I'm on a private server and I need them since we didn't upgrade to Cataclysm" is a BAD reason - and it's illegal.
At Level 38, you unlock an additional pet ability. The ability you unlock depends on the spec of your pet. Ferocity pets gain Primal Rage, which is a Bloodlust/ Heroism effect that increases the Haste of you and all party members by 30% for 40 seconds. Tenacity pets gain Survival of the Fittest which reduces you and your pet's damage taken by 20% for 6 seconds on a 3-minute cooldown. Cunning pets gain Master's Call which removes all movement-impairing effects from your pet and a friendly target, and makes them immune to movement-impairing effects for 4 seconds. The friendly target can be you. It has a 45-second cooldown.
The entire Jade Forst is our farming spot for this one. Literally, the entire Jade Forest. The Jade Forest is crawling with porqupines and if you have a mage character, each one of them has chance to drop the polymorph porqupine tome. Which is excellent, because these tomes have a selling point of 13,000g across the board. They are really easy to get, and noone really pays attention to these spots. Try it if you like, I was able to get 2 on video, and have already sold one of them.
The most important step in being able to buy a mount and make other large purchases should be self-evident: saving. Economize as often as you can, and don't buy anything unless you absolutely have to. You can burn through hundreds of gold even before level 20 by visiting the auction house for new equipment at every opportunity. If you do so, over the long haul you will be left with very little to show for it. Before level 20, keep your eyes on the prize: getting that mount. The mount helps you move faster. Faster movement means faster killing, faster questing, faster quest turn-ins, and faster leveling. It is the most important tool to fast leveling you can get at level 20, and infinitely more important than getting your hands on that Left-Handed Vorpal Cleaver of the Zipswitch that you could have purchased at level 23. Stay focused.
From “The Burning Crusade” expansion, weapons like Klinge der Zauberei, Die Nachtklinge and recipes for different weapons are really valuable. The best example is Pläne: Teufelsstahlangschwert, worth 500.000+ Gold. These items are World Drops, you can find them in all raids and dungeons. I don’t know any Open World Drops, but that does not mean there are none. Another great transmog source are world bosses and rare spawns on Outland.
