Hey!
Sorry for the delayed response

The post passed me by. Bump successfully received

And thanks fire for the clarification, it helped me show the stats guys what's going on. I replied to your post with the same answer:
"Witchcraft" was an old naming convention. That witchcraft skillbook is the actual necromancy skillbook.
The missing necromancy scroll and scroll recipe are indeed shortcomings due to the stats using the wrong name (an unfortunate mistake due to the 2 names). Thanks for making us aware of this!
Sincerely,
Kevin
