Hello! Thanks to Paradox, we have gotten our hands on the upcoming Royal Court DLC. We have started the adaptation by diving into new mechanics right away, such as artifacts. Of course, the first on the list was Frostmourne, which will play a big role in the upcoming Arthas' event chain. You will get more details in the upcoming developer diaries.
The adaptation is a very exhausting process, so you may restore our nervous cells by supporting us on Patreon.
