So I was looking through the journey notes and I came across something weird. On the second page it shows how much total mana you got with the separate gems throughout the game. Now, as far as I know there are 9 gems in this game and it shows 10 gems under that section the original 9 and 1 is question marked with no extra info. Am I getting to excited here?
There are only 9 gem types there. First row is total mana spent on gems throughout the entirety of your playtime, rest of columns are the portions of that spending which were on specific gem types.
