Questing

Quests are a big part of World of Warcraft. Like most other role-playing games, World of Warcraft lets you advance in level as you gain experience. Experience can be gathered by killing monsters, exploring new destinations, and completing quests. Unlike in other games, quests are a significant tool for level advancement. Players who try to level up through sheer combat will never advance as fast as those who combine questing with monster killing.
Sprinkled liberally throughout the game world are hundreds of quest givers who provide thousands of quests. These quests can range from the simple to the complex. Some quests ask you to kill a set number of beasts or monsters, others ask you to collect trophies from creatures, and others ask you to slay unique non-player characters or named creatures. Other quests ask you to deliver documents or items to other NPCs, escort important characters out of danger, or recover artifacts or lost items from fortified dungeons. Although many quests share a similar structure, all of them are presented by unique NPCs who deliver interesting backstory with each quest, which in turn brings the world alive and gives each quest a unique flavor.
Although those who love the story will want to dive into the quests for the lore they reveal, many players will also want to complete quests for the experience and the rewards. Nearly all quests give sizeable experience rewards.
Many quests also provide material rewards, such as cash, potions, food, drink, magic items, armor, and weapons. Some of the best equipment you can find in the game will only be available as quest rewards.
