Did you know that MTGA keeps a detailed log of all your in-game and draft events? These logs can be used to determine your vault progress, figure out your win rate, or even to enable third-party tracker applications, like Draftsim’s amazing Arena Tutor app.

Well, at least that log data was there until September 4, 2019. On that day, an update was pushed to MTGA that caused several Arena-related applications to break and a lot of people were left wondering “where did my vault info go”?

The good news is that it’s not gone, it’s just been hidden by Wizards of the Coast. Supposedly this change was made to help address slowness and performance issues in MTGA. The effect was debatable, but if you need to turn it back on, here’s how you do it.

Enable Detailed Logs (Plugin Support)

First, log into Arena and go up to the settings menu labeled “Adjust Options” in the upper right of your Home screen.

Next, click on the view account button on the bottom of the Options screen.

This displays a bunch of “hidden” account options. Make sure to click on the “Detailed Logs (Plugin Support)” button.

Enable detailed logs plugin support

And that’s it! Click the arrow to back out of your account settings and click out of the options screen.

Update: You may need to exit and restart MTGA for the changes to take effect. Start playing again afterwards to generate a new log file.

After playing, you can confirm that your vault progress is shown again by using the method outlined in our article on checking your vault.

Where Is the MTG Arena Log File Located?

Great, so you’ve enabled detailed logging, but how do actually check that file?

There are times you may want to grab or peruse your log files, for example to get additional information on your games or to submit a customer support ticket or bug report to Wizards.

First, go to your start menu or File Explorer in Windows and type in the following and hit enter:

%appdata%../LocalLow\Wizards Of The Coast\MTGA

This should bring you to a folder with a path like this:

In that folder, there will be a file called Player.log

The Windows folder containing the Player.log file

That’s your log file. If you open up Player.log, you’ll see all your detailed match and vault info.

    In my experience, I had to exit and restart the application after enabling detailed logging, as “vault” was not in the file I generated before exiting. The vault information was present after I exited, restarted, and generated a new log file.

      Thanks for mentioning that, that’s a great tip.

    For me, the detailed log was already enabled but I don’t find the progress in the log file anyway.

      Not sure why this would be, but one possibility is that you don’t have any vault progress? So perhpas it didn’t create a line for it in the log?

    This does not function as of Apr. 3 2020. All steps in article followed, including enabling of detailed logs.

      Matt – what exactly do you mean? These steps are to enable detailed logs. Are you trying to do something else? View your vault progress? Use Arena Tutor?

    I have followed the steps and now i have a Vault in my log BUT Arena Tutor still keeps saying i need to enable detailed logs. it is and I have played MANY games to get some sort of Dater for the logs

  • James Sugden June 10, 2020 9:43 pm

    Hi I have set up Arena Tutor and I have enabled the logs as you suggest but I cannot get the tutor to give advice during draft picking. It works to log my deck and progress when I play an actual draft game but not during the actual card picking. Is the advice during draft picking not functioning with ikoria?

    • Dan Troha June 11, 2020 9:06 am

      Hey James – ever since Ikoria came out, there has been a new draft mode for human/player draft. MTGA created a game log change and no one has been able to access in game draft information for human drafts. HOWEVER, we are imminently releasing an update where we’ve figured out a solution to this issue. You can expect it to automatically update in Arena Tutor in the next week or so.
