I loved making modules over in NWN toolmaker. I was even a featured module maker back in 2003 for a “cheat” module that let you make your own weapons and armor or edit the current weapons or armor that you have.
It may sound common now, but there wasn’t such a thing back in the day.
The reason I’m hoping for something like this is because they have this feature for the Divinity Engine 2. BG3 runs on an updated version of that, Divinity 4.0 engine.
So hopefully it won’t be too much of a hardship once they get things where they want it to be. After all, I assume they have something in-house that they use to do something similar. So, with luck, they can package that.
If they don’t, then maybe we can get something from the modding community.
