iMobility=1 Doesn't seem to increase mobility in my case .
Actually, I don't recall that anyone ever investigated what the "iMobility" property is supposed to do. (Is it an increase to the distance moved, or the ability to fly, or what?) What we have found is that some properties are linked to specific armors, characters, or weapons, and this may be controlled in "native functions" which we cannot examine. They are not activated simply by including the property. Also it matters whether you are playing EU or EW.
