Well I had Gwalhir, Mahakaman Rune Sihil, Aerondight, Raven's armour and D'Yaebl. All were imported except D'Yaebl. You can't have all 4 swords on you at the same time. I believe that's the problem. More specifically, the fact that I just left D'Yaebl on the floor at the dentist's location? I reckon if I gave it to Dandelion as storage it would import.
Now if only I could have it through console commands. I just found the Arbitrator in Chapter II and it's got damage that's above and beyond all imported swords. But i'd still like to at least see it in Witcher 2. Raven's armour is unarguably the most useful and worthy thing of importing into Witcher 2. Very good armour to start with.
