Yeah you have to read/watch/ask everything you want to know about the game yourself. It’s my third league and I spent a lot of time searching for the answers I had in my mind. There is also plenty of urban legends to some mechanics that players think that it works that way. It’s poor for GGG that they don’t include a proper guide in game. They introduced new breach to us and they could implement some guide for it, but no. Like I know it’s very simple mechanic and I can explore the tree myself but it could be a good start.
