Using the NwHak utilility, I updated the following files in the hak - prc_2das.hak:
cls_spbk_dnecro.2da
cls_feat_dnecro.2da
I added the following line to the bottom of cls_feat dnecro.2da:
1117 TurnUndead 294 3 1 1
TurnUndead was listed previously, but it was indented incorrectly and was deleted.
The changes to cls_spbk_dnecro.2da (in the zip file) should be attached. These changes do seem to work.
I tried adding the ArmouredMage feat, but it didn't work. It showed up in the list, but I still got arcane spell failures.
Anyways, hope that helps.
As for programming, right now would not be a good time for me. Perhaps at another time.
Thank you.
