While the primary professions are very useful, players should not neglect the secondary professions of First Aid, Cooking, and Fishing. The WoW Professions Guide will tell you that all players can learn all three in addition to the two main skills they already know. And whether you’re level 8 or level 80, secondary professions can offer you some distinct perks.
WoW profession guide for cooking.
Players quickly realize that food is a necessary part of the game. Eating food will help you replenish your health (and in some cases your mana) much faster than you would on your own. This allows for less downtime between fights and faster leveling.
Food can be purchased from various vendors throughout WoW. It can also drop from humanoid mobs, and in the lower levels you can find food boxes.
A much cheaper way to get better food is to learn the skill of cooking.
When you kill beasts during your quests, you will sometimes find that they drop meat. This can be sold to the vendor, given to a pet if you are a hunter, or cooked for your own uses. Fishing will give you fish. In some cases, fish can be eaten raw, but cooking it gives you better health regeneration.
Another thing to remember about cooking your own food is the fact that many foods will give you a “well fed” buff once you’ve spent a certain amount of time eating them. Even if you’re a healing class and don’t need to eat food to replenish health, the “well-fed” perk makes learning to cook worthwhile. These perks level up just like food, so foods designed for players over level 70 have much higher benefits than foods designed for players over 20. some even create a “feast” that can be shared with other members of their party.
