I drew my 18 skill icons in Photoshop; it was a very time-consuming process. I wish you patience in this tedious task!
I saw this, and that's why I wouldn't want to do this for every other patch.
Fortunately, things will be simpler and more practical for me, but of course, doing it for the first time will be the most time-consuming. In addition to the changes themselves, I also need to create background/interface textures, and unlike the skills themselves, not everything can simply be "extracted" from the game.
But then it will be very easy and more convenient to work with the mod. There is already a significant foundation for further expansion, such as adding a "Bestiary" there, buildings, and generally anything else you want... (But that's for later; now I need to do what is required)
