Hi AGAIN Ryan, heh. Here are a few answers:
1)Easy, just give the amulet a tag (bottom right on the item wizard). Then when making a door, go to lock, select only opened by key, and type in the tag of that item. Then only that amulet will open it.
2)Hmmm, u could use a hak, or choose Rural, and make some raised ground. Then put something like a temple(good) on top and make and entrance through that temple, into the inside of the castle.
3)Well, there are some long beard and hat haks already at nwnvault, just go to
http://nwvault.ign.com/Files/hakpack...ackslist.shtml they will have those things there.
4)Just edit the appearance of the robe, and change the colours to green. Or you could just make your own new one.
5)Hmmm, well, you could make an area transion into it, but you would have to enter the arena manualy. But you can also talk to an NPC and when you ask them to teleport you to the arena, you will go there. But personally I don't know how to do that.
6)Hmmm, Maybe a fighter with some spell resistance could, but a wizard might not. Just edit the stats of the Lich to make it a little weaker. A clue is to look at the CR (challenge rating) of the lich. If it is below 5 then yes, they probebly could take it on.
Hope that helped. And I cant wait to play on your mod, heh.
