Thank you very much for your kind explanation. Sorry for asking unnecessary questions due to my lack of study.
I understood the explanation and I think I can create a new custom item through this. Thank you again for your ability and kindness. :)

Simultaneously, you can even assign your custom weapon configurations to custom monsters, provided that your monster has fields similar to HandItem. In that case, it can be assigned a weapon ID.

Regarding your second question, I have introduced the concept of ID for skills in Dungreed, where each skill will have its own unique ID. Suppose your custom weapon was originally based on template weapon A, which comes with a skill of ID 1. Without any modifications through the configuration table, the skill of this custom weapon remains as ID 1. You can modify the skill's ID just like changing other properties of the item through Data/Property. Therefore, if you need to create a custom skill and configure it to your weapon, you just need to follow the steps to craft the skill and then enter its ID into the item configuration. This has already been implemented in the GirlMaker example I mentioned earlier.

I have unified the configuration of crafting skills and items, so you will find that the configuration table for skills and Item are almost identical. The logic still involves using Data to modify attributes and using Costume to change appearances. You can subscribe to the demo mod GirlMaker to learn about its configuration method.

I want to customize the skills of a custom weapon, is there a simple guide?
Also, when I customize the skills, will the skills of the base weapon of the custom weapon be changed?

Thank you. If you encounter any problems during the process of trying to make it, please feel free to give me feedback.

It's such a fantastic feature. You are creating The Second Dungreed. If I get the chance, I definitely want to make additional skins.
