I'm working on a custom ability that adds an enhancement bonus to any one attribute score. Which score gets adjusted can change each time you use the ability. I have the custom ability set up to choose an attribute, but I can't see a way to determine which item was chosen. There is a usrChosen1 field, but it doesn't get populated. There must be a hidden field somewhere (the livename changes, but that's it as far as I can tell from the debug fields/tags). Is it possible to access this hidden field, or do I need to create something else that I can bootstrap?
