I've been redoing my game challenges so that they don't just add XP when completed. One thing I'm doing with some of them is adding an appropriate skill point, so my character develops by doing as well as by having skill points to work with at level up. I've been able to make all of the skills work through a basic challenge script, except for sneak. The only Misc Stats that apply aren't ones that I ever use, like Pockets Picked and Pants Exploded, and there's no conditions I can apply for doing damage/killing while sneaking. So I've been trying everything I could think of using a combination of GetLastHitCritical and either IsSneaking or IsActorDetected, then having a positive result modify the Pants Exploded stat so I can use Sneak Attack Criticals for a challenge stat. But nothing I've done seems to work. I've tried a quest script and a Perk ability, but I can't get anything to mod that particular stat. If anyone can offer any suggestions as to how I can make it work, I'd greatly appreciate it. I've pretty much run out of ideas at this point.
