How to use the Summoners War Rune Optimizer ?

Rune Optimizer Summoners War

In Summoners War, it can quickly become tedious to run your monsters properly. Indeed, there are many things to consider when choosing the right runes. Does your monster need to increase its attack? Its speed? Critical damage? Its accuracy? Its defence? Generally, a monster needs several stats and sub-stats, and it is not easy to assign the most appropriate runes to it. Moreover, it is not alone, you also need to run the other monsters of your team! How can you balance the stats of your monsters without spending a lot of time? The answer is: Rune optimizer! It's a program that will take a lot of the pain out of your life with ease. We explain everything in this article!

What is the Summoners War Rune Optimizer tool?

The Rune Optimizer is a program that allows you to create rune compositions for your monsters in Summoners War. In other words, custom-made rune sets for each of your monsters. Rather than searching for each rune by hand to make your monster indestructible (a long and difficult task!), you can use the Rune Optimizer software. Well, you still need to know the stats you want for your monster! But you will save precious time.

Rune Optimizer, how to make it effective?

It's not rocket science, to get the Rune Optimizer to work, just follow us step by step. Start by downloading the version of Summoners War Exporter that suits your computer (if it's a Mac or if you're on Windows 10, it's different). This is not an Android or iOS version of the Rune Optimizer Summoners War, but just Windows or Mac ! Once you arrive on the page, you will have the choice to download the version that suits you. For Windows 10, we advise you to download this one:

Then open the Summoners War Exporter application.

This software will allow you to retrieve information from your runes and monsters in order to make the Summoners War Rune Optimizer work. First of all, you need to be connected to Wi-Fi.
💡 A little tip: if you don't have one available, you can simulate a Wi-Fi network by sharing the connection of another mobile phone.

  • select the Wi-Fi address,
  • click on Start Proxy,
  • go to your phone's Wi-Fi settings and then to "Advanced settings",
  • click on Proxy, then enter the software information (the name, for example, which starts with 192. and the port, which is 8080).

Once this is done, start Summoners War. Wait for the Summoners War Exporter to say "Success, yourmomentary.json". You can now turn off the proxy and restore your phone settings.

Let's get down to business. From now on, you can download Summoners War Optimizer or use directly thededicated web app. You are now in possession of the famous Rune Optimizer for Summoners War, lucky you. Once installed, open the Rune Optimizer application.

When it opens, click on "Pick a file", search for your .json file, and finally press "import it".
You're there! Let's move on to the inner workings of the Rune Optimizer!

Rune Optimizer, how does it work?

The Rune Optimizer software is rather intuitive and does not raise any major difficulties. We will show you how to do it! You can select the monster you want to optimise here:

Rune Optimizer monster selection

Select the monster you want to run. Once this is done, you can choose the sets you want it to have and the main stats.

Furthermore, you can exclude from the build possibilities the sets you don't want to be assigned to your monster.

Then you can choose the substrates you want to appear on your runes (atk%, def%, spd, hp%, etc.).

Rune Substrates

Also, in the Rune Optimizer's Option section, you can choose whether or not to avoid taking runes from other monsters. But also, you can choose to take only the runes from your inventory. Finally, you can choose to only see runes with +3, or +6 or +12 etc.


Broken sets can be avoided very easily by ticking a box.

Also, you can choose to put a minimum and maximum requirement on your stats. If you want your monster to have a minimum of 200 speed, then the Rune Optimizer calculates all possible combinations so that your monster gets them according to your runes.

It is also possible to simulate the stats of the runes below the optimize button.

Finally, click on Optimize and the Rune Optimizer will start its calculations. The builds will appear at the bottom of the application. It is also important to know that you can sort the results (for example, if you want to see the combination that gives you the maximum critical rate, or the maximum hp, etc.).

Click on Optimize

And that's it! You are now a runage ace and a professional in the use of the Rune Optimizer!
