I started a Duergar run. Curious to see if there were special reactions/interactions, but so far (act 1 up to druid grove and blighted village) nothing much new. Quite contrary to my former drow character who gor much more feedback on her race. Duergar seem to be no surprise to the faerun locals.

I used the Tav hairstyle mod for her hair, and now an interesting thing occurred.

When she puts on a hat, her hairstyle changes.

When I first saw this , it was annoyying, but now I find it amusing to change hairstyles at the tip of a hat.
