I dug up my old copy of Neverwinter Nights Gold plus the Hordes of the Underdark expansion pack. I installed that, updated it and added the big PRC hak pack. That added lots of new options, spells, etc.
I am nearly at the end using an elven pure wizard with most of the Corpsecrafter feat tree. The undead do alright but rather top out with the mummy, at least for wizards. Higher level create undead spells are available, but what they create is actually weaker than the mummy. Besides, the mummy's fear aura works well until upper levels at breaking up large bodies of enemy. Once gained access to ninth level spells, I took the Baelnorn template. In that game it takes four levels to get the whole package with no gain in caster levels, but the benefits seem to have been worth it. Paralyzing touch worked quite well against many of the enemies, though not all, and the damage resistance has been a life saver many times.
Some of the new spells from the PRC really made some encounters easier, but I won't give that away unless asked about them.
I'll probably play again soon and try the mystic theurge.Pity about the game's hard bias toward making your character good or I'd play human and go neutral to try the lich template (you, you can play a neutral lich but only elves can be baelnorn).
Its still a challenging and fun game after all this time.
