Zero, it works against any race's regular abilities such as bash, vamparic aura, and jack shit. It is just that how it currently works is there is a timer or something that runs for a while then cuts out. Read page 13 or talk to Cyber for more info. I know for a fact that it is currently working because of testing previously done with Wolfenstinger. Sometimes he would shoot me 29 times and vamparic would proc 17ish times (which is about 60% proc) and other times there would be 0 out of 29 procs. This is the same thing that happens with molecule. Either every shot goes through the bubble or no shots go through. The code that prevents abilities from affecting the Shadow Hunter is correct, but the code the decides when the Shadow Hunter is immune is what is wonky. I hope that helps with your reprogram of the ability for Kakshi (if you decide it belongs there). I'll be sad to see hex gone from the Shadow Hunter toolkit--especially since there won't be a hard counter for Molecules and running around with the ultimate and not getting perma bashed is awesome--but the slow looks pretty nice too.

If you want to see any of it first hand, I'd love to show you even though this computer sucks.
