How do you set a variable class ability (like sneak attack) as a prereq for a feat? I've tried it various ways and I just keep getting errors when comp'ing, but the rest of it goes through fine. I may even be using the wrong names, but have tried all of them that I could find for sneak attack listed in the other dat files. [The feat I was adding was Arterial Strike from the CW book, so not having that show as a Prereq won't matter much, but it's jut bugging me and stuff!]
