I have 2 questions ( one probably very simple and 1 I hope is as simple).
1) I was attempting to get another sword saint katnana forged but when I put the correct items on the forge the smith does not recognize them. I already have one made and I would really like to dual wield with 2 of them. I have a +3 katana and the adamantine but nothing happens. Do have drop the one I am carrying 1st and then build the new one?
2) Is it possible to import your character from NWN to shadows of undertide and hordes of th underdark? I am really enjoying the character I build ( normally I have just built new one for each game ) and I would like to try to get him as high as possible.
As always thanks in advance for any information.

1) The smith will make only one of each item.

Hold on to your +3 katana and the adamantine. In chapter 3 you will get the chance to forge an even better katana.


2)Shadows of Underntide assumes you start with a level one character. It is possible to import a high level character but it would make the game too easy to complete. Hordes will set you to level 15; adding or deleting levels as necessary.

If you want more levels check this thread where I found a way to get more XP in the Original Campaign
