Speaking of dwarves and duergar...

In the dwarf helpfile it says dwaves resist disease and poison. No mention of magic.

In the duergar helpfile it says duergar, like their dwarves, resist magic and poison. No mention of disease.

So...

If dwarves resist magic, that should probably be mentioned explicitly. (Like in the svirf helpfile).

If duergar, like dwarves, resist disease, that should probably be mentioned explicitly.
