I finished chapter 10. I might be able to finish this tomorrow, chapter 11 is only 21 pages.
I am really not sure I want to implement the skill pyramid. I like the skill selection at start but the idea that you have to have one skill stack on top of another is kinda silly to me. Maybe it will make more sense in game but right now I am considering changing it, even if it does make it easier for the characters to advance to high skill.
