I'm sorry. I didn't realize that I didn't.
I am using the default Bioware XP system, but I can switch to one of the PRC ones if it will do what I need.
I want to run around with a ton of undead and still be able to level.
Turn the Bioware XP slider down to 0 in the module properties.
Set the following switches in the module variables:
PRC_XP_USE_PNP_XP = 1
PRC_XP_USE_SETXP = 1
Test out the module. If that still isn't doing what you want, try adding these switches:
PRC_XP_SUMMONED_PARTY_COUNT_x100 = 1
PRC_XP_FAMILIAR_PARTY_COUNT_x100 = 1
PRC_XP_DOMINATED_PARTY_COUNT_x100 = 1
The documentation isn't crystal clear, but I think the above switches will make summons, familiars & dominated NPCs not count very, little towards XP calculations.
