Question on modding ability duration

[bloodsin]

A bit of a n00b question but I haven't found an answer that I'm sure of yet and I was hoping that someone could help me.

I'm hoping to mod the duration of some cipher spells / abilities. Things like "whisper of treason" which reads that it has a 10 second duration, I'd like to change this to be longer but I can't find a key in the ability unity3d which lists the actual 10 second duration. I'm not sure if that is because that duration is calculated elsewhere or if I'm just missing it. Someone mentioned a "Duration Override" key but I don't see that, but I DO see "Duration Adjustment". I'm not sure if that's the same or if I am completely off in my approach.

Any help would be appreciated, thank you!
