The leveling guides on my site are essentially speed leveling guides. My leveling guides are the same guides I use myself to speedrun to 60 on new servers to get 60 server first. I list many occasions where I tell the player to "die on purpose" to go faster. I tell the player to skip certain quests, because some quests are just not worth the time/XP. I list tricks and shortcuts to go faster so you can reach level 60 much quicker. I am still constantly going through them over and over again perfecting the guides to make them faster and easier to follow. For the most part, the guide can be followed without the need from other player's help, as the whole guide was made from a solo run anyways. Although I do list quests that can optionally be done if you have a group.
First thing you should do is to learn the market for the specific item you would like to monopolize. Let’s say it is Kingsblood. We can see a stack of Kingsblood is selling for 1 gold. There are 10 stacks on Auction House. To control the market, you have to buy out all the lots of Kingsblood, even single ones. Next move is to make auctions of Kingsblood you have bought for the price you want. Be reasonable and make it 2 gold. But all people are still being used to the old price of 1 gold and will not buy your Kingsblood at first. You have to maintain your auctions for 2 gold all the time, no need to put all Kingsblood you have at once, 3-5 lots are enough at the beginning. You can see, other sellers may start create auctions for 2 gold as well. That’s what we need. But if someone is selling for cheaper price, buy out their Kingsblood immediately. Soon people will start to accept your price of 2 gold as a regular price and will buy your stuff. Now you just to have to sell all Kingsblood you got. Control several markets. It can be anything, even twink blue items or items level 20-30 or 30-40. Same strategy works everywhere. It requires lots of time to track the markets and check auction house. It is not that easy as it may seem, you should spend at least a week of monitoring to be sure about prices, you will fail if you buy out everything at once without research. Soon or later, too many people will decide to sell your item as well. As they could see price change and think it had happened naturally. Market becomes overflooded. It is important to quit before the collapse. This always happens.
