Looking for Permanent Necro Call mod

[BB Shockwave]

Thanks - I saw that icon on screens but could not figure out what it was good for. Good to see AP will have an undead-raising spell (strange that it is order magic, though)! Does this mean the english demo is out? (and btw, how did you get your character to look like that?)

I require a little help with the mods - I never used these dds files before. What do I do with them, where do I put them?
