I looked up the combined artifacts for Heroes 5 in the wiki, and it seems like something is off. The screenshot shows the description from the wiki and from the manual. And it's like that everywhere.
Wiki loads cards from the knowledge base, and both the wiki and the knowledge base are open for edits by all registered users — if something is wrong, I suggest simply making the edits.
If there's an issue with how the cards from the knowledge base are displayed on the wiki page — i.e., the knowledge base shows one thing and the wiki shows another, that I can fix — that's a technical matter.
But the content, accuracy, and corrections are a matter for the community.
Initially, the knowledge base was built on game data and manuals, and each card indicates where the data was sourced from, but due to the large volume of data, there may certainly be parsing or transfer errors somewhere, and something might not match up.
If you need to adjust the parameters of any game object, the knowledge base has an "improve page" button https://heroesworld.ru/kb/contribute/artifact/44/
The changes should automatically appear in the wiki where those cards are used.
Of course, I'll go through all the materials and try to double-check everything again when I have time, but I don't think this is a one-person job — the whole point of these two sections is openness and collective contribution; I only laid the foundation.
