Since the import to Wiz 7 did not take into account the party's actions (and which NPCs were offed or not). Their is not Wiz 6-> Wiz 8 import, so no bearing on Wiz 8.As for Wiz 7 -> Wiz 8 ... you have the powers of ressurection ... so did some of the NPCs on Lost Guardia
THe only thing I have seen make a difference is that some of the NPCs will say things like "I remember you" or they may start out neutral instead of friendly.
