Power leveling is the term used to describe the process of leveling a character as rapidly as possible with the least amount of play time. It can be used from any level up to level cap. Contrary to what many believe, efficient power leveling does not require endless hours of grinding. The best methods of power leveling involve doing many quests in an orderly fashion.
Cooking benefits all classes, especially melee and hunters (it is a free source of food). Until higher levels, the benefits it provides are almost exclusively stamina buffs. While more stamina is always nice, cooking is not essential to leveling. Considering the time investment required, if you pick up skinning then cooking would absolutely be a wise skill to level prior to hitting your level cap, as beasts often drop meat useful for skilling up.
Power leveling is the process of handing over your character to another player (usually it's a seasoned WoW player), who then gets your character to the highest level possible in the shortest amount of time. In essence, someone else does all the hard work for you so that you don't have to waste your time by leveling the character/s yourself. And as with most other MMORPGs, there are a lot of players who offer such power leveling services for World of Warcraft.
Determine the gear stats and armor type you need for your new character. For example, a paladin requires Strength as their main stat, and heavy armor (the armor type) will scale as the character scales if they are initially unable to wear heavy armor due to being a lower level. Your optimal heirloom gear set will feature the same main stat as your starting gear.
- The auto trash sell feature is also incredible, but I always had issues with it selling gear efficiently. Often I have to open my bags 2-3 times if I have a lot of trash, because it can't clear it all in one go. There's also a very noticeable delay with this feature when opening the bags, almost like the bag UI is freezing for a few seconds, then it clears. I've started using a different add on for auto selling trash and it does it all instant, no hiccups, no nothing. Just one swift move.
The World of Warcraft API has a list of functions that you can interact with and to talk with WoW using Lua. These are your building blocks for manipulating WoW windows and chat boxes and so forth. Looking at these for the first time can be very daunting. But don't be discouraged. After getting more familiar with Lua the WoW API gets much easier, and the documentation gets much easier to read. Keep in mind there are many different ways to accomplish your goals, so when going though the API keep looking until you find a way that best suits what you need.
