2Qwerty: I just remembered that I once wrote an article about the lack of a penalty for shooting through castle walls. Maybe it will be useful?

Absolutely. In the beta or a later version, a "combat" section should appear. Within this section (or perhaps separately), there will be a subsection dedicated to castle sieges.
I am currently gathering clarifications and opinions. It's interesting that, for example, hyperlinks are not convenient for everyone. On the other hand, for some, they are convenient.
The situation with images is also ambiguous. The more images, the larger the file size and the slower it runs. Currently, the images are arranged according to the following principle: you see a unit on the map, you go to the reference guide, you see it there, and you learn everything about it. Or you see an object on the map, you go to the reference guide, you find it, and you read about it. The same applies to artifacts.
I decided not to include images of spells. If a spell exists, it is already labeled, and you can search for it by name. Another question is the "difficulty of translation"... In general, the issue of spells is ambiguous.
The next point is objectivity. Currently, the reference guide lacks a subjective component. But if I start giving recommendations on building, upgrading, or conducting battles (as I do in my articles), objectivity will begin to blur. After all, these recommendations are far from indisputable, and their scope of application is limited. They are not universal recipes. In this regard, I am not in a hurry to fill the reference guide with life, sticking closer to the tables of Bradis. If I create a section with recommendations, it will probably need to be somehow separated. Or maybe it's better not to do it at all.
