"but there's not necessarily an explicit way to do something."
That's a phrase that keeps popping up when we talk about modding around these places.
Seems to me a bad omen for the future of modding in D:OS2 if you ask me...
No game ever has an explicit way to do everything modders want. In this case, I meant there's no command that can directly modify a skill. That would be amazing and would open many things up, but that's a big request that would probably require reworking how the skill code work to a certain degree, and whatnot. But there's probably ways to accomplish what WMC51 requested.
It's up to Larian to add all the fundamental components for modding and make as much of it the game as accessible as they can. Which so far they've done a fairly decent job at. Despite D:OS EE's flaws, it was actually one of the most moddable games of its quality and scope in a long time. User interface and documentation left a lot to be desire, but the capabilities were there. Obviously the combo of power and ease of modding is the holy grail, but power is more important than ease in my book.
It's up to modders to develop systems with the tools we're given. Often it just takes developing a systematic approach to doing things, and whole new things are possible, and other people can just plug their own things into those systems, or follow tutorials to do something similar. Larian can't predict everything we might want to do, nor can they code everything up even if they did, so other modders fill in the gaps.
Ideally we can get something like a "modding patch" a month or two after release, that adds new scripting commands and various features in response to the limitations and difficulties modders find. Like, something that might help WMC15's request without being a huge deal to code would be to add a "stack priority" to skills, where you can know either an empowered skill or its default variant, and not both at the same time, and the empowered variant would automatically replace the default skill. There maybe a way to script something like already though, if you're clever enough.
