I mean, that's more of a case of the product page being wrong than the book which went through editing, but this is also a 400 page indie crunchy tactical book, so I can't promise there are 0 mistakes in the game. Thank you for pointing this out, I will update the product page. If you'd like, you can look at the player's guide for free to determine if the game is for you or not.
That is actually option, thank you. Sorry but I'm really frustrated by the absurd amount of games (not just ttrpgs) with good ideas and graphics, and really bad realization. So I tend to trigger if I found a clear mistake in the first lines that I read of a new thing. Moreover english is not my first language, so when I encounter something weird I need to spend some time to understand if it's my fault or the text is really confusing.
