WoW gold:: skill

Characters have access to a huge variety of both class-specific skills (class skills) and general-use skills, called professions. Class skills are determined by your character class and are an integral part of your character. For example, a warrior's sword skill, axe skill, and mace skill are all considered class skills. There are also a wide variety of professions available to all players regardless of class, allowing players to customize their skill set. Examples of professions include alchemy, blacksmithing, and herbalism, to name a few.
Can you tell us more about professions? Professions are learned from various trainers around the world. Some professions will be rare and hard to find trainers for, while others will be much more common, with trainers located in multiple cities. Professions can be broken into two tiers: primary professions and secondary professions. Players can learn a maximum of two primary professions. In order to learn a new primary profession, a player must unlearn one of his or her existing primary professions first. Secondary professions are less versatile and robust than primary professions, but there is no limit to the number of secondary professions you can learn.
How do you improve your skills and professions? Players improve their class skills through a combination of usage and leveling. Class skills related to a character's class abilities, such as a mage's frost skill, which improves his frost spells, automatically increase when a character levels. However, weapon and defense skills only improve through usage. Thus, in order to improve your ability with swords, you must equip and fight with a sword. Professions operate similarly. In order to increase your skill level in a profession, you must use it. For class skills, even those that you increase manually, your character level dictates the maximum skill level you can have in a particular skill. For professions, your profession rank - apprentice, journeyman, expert, and artisan - determines your maximum skill level.
Is there a way to retrain talent or skill points? Yes. If you unlearn a profession, you can return to a trainer and relearn it. However, your skill level will be rest to zero and you must increase it yourself.
Do skills atrophy if they aren't used? No. Once you learn a skill, it's yours for life unless you decide to unlearn it.
Is a Hunter who trains in bows and rifles better than say a Warrior who also trains to the same level in said weapons? Both classes have the bow and rifle skills; however, the Hunter has unique class abilities that improve or enhance his attacks with bows and rifles. These additional abilities are what ultimately make Hunters more powerful with ranged weapons than Warriors.
Can players create their own items using trade skills? World of Warcraft features a wide variety of professions that let players gather resources from the world to create numerous unique items. Players can make bags, bandages, weapons, armor, potions, and many other things.
What kinds of fish can you catch with the fishing profession? Are there special items, treasure chests, or S.O.S. bottles that you can catch while fishing? In addition to a wide variety of different fishes, players can also catch things like lockboxes, crates of engineering supplies, unique armor, and weapons. However, the chances of this happening are exceedingly rare.
How many professions can a player master on an individual character? A player will be limited to two primary professions. You can have as many secondary professions as you want.
