The Undermine Journal:

The Undermine Journal (TUJ) is, without doubt, one of the most crucial websites/add-on resources for gold-making in World of Warcraft. Using TUJ website, add-on, and TSM together and knowing how to use them efficiently will maximize your gold-making potential.

Within all my gold-making articles, I always express the need to access TUJ website so readers that consider following my advice (incorporating my markets into theirs) can get up-to-date auction house data for their region and realm. Having this information to hand before getting into a market is the difference between knowing you’ll make a profit or record a loss.

The article today will hopefully give my readers (that are unfamiliar) a better understanding of The Undermine Journal website and add-on. 

What is The Undermine Journal (Website):

The Undermine Journal (alternatively known as TUJ) is a website that offers auction house data for the specified Region/Realm you require in World of Warcraft. TUJ acquires this data via snapshots from Blizzard’s API, which is updated every hour.

Once you’ve selected your Region/Realm, you can input any item in the search bar, and it will offer you essential auction house data for that item. With this auction house data, we can correctly value our item(s), making buying and selling as efficient as possible.

What is The Undermine Journal (Addon):

The Undermine Journal in-game add-on shows realm-specific pricing in tooltips for all items and battle pets on all US, EU, and KR realms. Data includes:

  • Average market price for your realm over the past 3 days
  • Average market price for your realm over the past 14 days
  • Standard deviation of market price for your realm over the past 14 days
  • Number of days since the item was last seen on your AH
  • Global median market price right now
  • Global average market price right now
  • Global standard deviation of market price right now

Prices are aware of item bonuses and pet breeds as well, so, for example, Heroic items have separate prices from Heroic Warforged, Mythic, etc.

The add-on is updated twice a week, on Tuesday and Saturday mornings. Update your add-ons regularly to have the latest release available in-game

The Author of The Undermine Journal (TUJ), Erorus, has added five Youtube guides helping players understand the statistics available from the website, and how using these statistics correctly is the difference between making gold and losing gold.

It’s difficult to believe at the time of this post; there were only 65 views! This should be a lot higher!

If you found any of Erorus’ guides helpful, appreciate his website and add-on; please consider becoming a Patreon and rewarding him for his work. I’m a Patreon as I believe what he’s created is fantastic. Rewarding him for his hard work can only be good for the website and add-on going forward. 


A portion of this article was directly from The Undermine Journal to offer precise information about the add-on. I’ve added the Youtube guides, this should not affect your view count – my intentions are to help increase it. If you wish anything to be removed, amended, please contact me, and I’ll immediately edit where necessary. I created this article to help promote your website, add-on and guides to new and experienced gold-makers within my blog.

TSM4.10 Guides

My Recommended TradeSkillMaster (TSM) GuidesTradeSkillMaster (TSM) is without a doubt the most powerful World of Warcraft gold-making addon to date. Without it, you’re always one step behind your competitors. Getting accustomed to TSM can seem daunting at first, but with some detailed instructions outlined by these guides below, the transition should be a lot smoother.

I don’t create TSM guides myself, but below I will add some recommendations of TSM guides that I believe will be a great asset to you. I’ve added links to their websitessocial media platforms so please drop by and leave some feedback.

I will update this post once more guides become available for TSM4.10 and later.


An excellent beginners guide, showing every aspect of TSM. Each installment posted below for ease of use. Samadan also streams on Twitch where he’s always happy to answer any questions regarding TSM that you might have.

[TSM4.10] All New Features and Updates
[TSM4.10] How to Install
[TSM4.10] Beginners Guide | Basic Groups & Operations
[TSM4.10] Profession & Crafting Operations
[TSM4.10] Sniper Setup | Create Sniping Operations & Groups


If you’d prefer a written format so you can easily follow the instructions, then I urge you to check out the TSM guide from TheLazyGoldmaker. This fantastic article guides you through every aspect of TSM. Thanks to the short and concise instructions, this is without a doubt a perfect guide to help new users (who maybe feel daunted by TSM) get accustomed to what TSM has to offer.

Please do consider TheLazyGoldmaker’s Patreon and reward him for his fine work.
