I'm not sure someone told you this already, but THANK YOU
It's very easy to use!
As a feedback maybe you could change the text colour when you have a specific change on a C5.
ie: the bow craft
"(C5: Dexterity, Max Action Points, or Speed bonus)" could be in another text colour.
Next step might be to get an icon for each element of this list, that would help people who are not English speaker to understand what it is etc..
Great job
