I like how the Deadeye visual effect looks and was looking for a way to apply it permanently to a character. What would be the easiest way to do this? Is the visual effect tied to to a particular statuseffect or does it exist separately?

If you edit it to say loop: true like other effects then you'll see what happens.  Either it works, it works abnormally, or it doesn't work at all.  You'd have to change the asset data (and possibly graphics) via the UABE to make it enable looping, but I have no idea how to do that other than the flashes of brilliance provided to this forum by Flavh69X (I can't recall if that's his correct username).

Hey, thanks for the reply. I ended up just adding the drug_deadeye ability via console for infinite uses and lowering perception by 5.
