I have just the regular NWN2, and I am playing through it for the first time. I am in one of the last stages of the game, second to last really, and it is quite difficult to catch a breath so to speak, so I went looking around to see if this sword is supposed to do anything, and then I find information about it in various forums and FAQs which talk about several different abilities that the Silver Sword of Gith has.
So of course, I figure this would solve my problems in the game, and then I attempt to use these special abilities. The problem is, I cannot even find the abilities. I have had the sword equipped since I got the thing, and put it in a quickslot, but clicking it or right-clicking it does not bring up any special abilities. I also have a second Silver Sword of Gith in my inventory. I've tried un-equipping it and re-equipping it, but this accomplishes nothing. I've found precious little about this as a bug, so I am wondering what I could be doing wrong. I simply cannot get an abilities menu off the thing.
