[PvK]

If I remember correctly, no it wouldn't be too hard. However there are two pairs of items which have problems:

Staff of Elemental Mastery
and
Twin Spear

Dom 2 doesn't have a mod command for items by number, so you can only mod one of each pair. I figure the best solution is probably to mod neither of them and let them be exceptions rather than having one of the pair modded and the other not.

Then I think the new items and spells in Dom 3 just need to be removed and that's about it.

I'll give it a shot.
