I was fiddling around with a little bit of modding earlier, including a little one I made to increase rate at which you gain category points.

Then I had the idea of altering or removing the limitation where you can't increase the mastery of a talent more than once, because being able to invest more heavily in specific talent categories might be cool.

However, after poking around for a little bit, I was unable to find anything that looked like it could let me make the change. Does anyone know is there's some varible that sets the maximum number of mastery improvements, or where the code that handles the category mastery improvement is?
