There are many ways to create custom summon mods for the game, and this how-to article is one of the easiest and most user-friendly ones.

If you are a beginner, you should start with the basics. In this case, you need to create a Yapped-Rune-Bear. After that, you need to edit the regulation file. The regulation file is a special document that tells the game which spirit to summon.

The easiest way to do this is to edit the document directly. You need to find the section that contains the spirit you want to summon. Then, you need to make changes to the text. The number in front of the spirit name is the number of the spirit you want to summon.
