Much of the PnP material can be directly translated to BG2 and I shall try to be faithful to the spirit of the rest. But I hope no one objects if I sometimes ask for community input on some of the less clear-cut PnP-BG2 conversions.
A preliminary list of undead that will be affected include Death Knights (you may know them as "Demon Knights" but they really are undead), Skeleton Warriors, Ghouls, Mummies and Vampires.
To start things off, Death Knights can, among other things, Turn Undead and cast Detect Invisibility at will:
Death Knight vs. minor undead
Death Knight in hot pursuit
