I was wondering what test is required if my group of pcs wishes to corrupt a whole group of npcs (numbering in the thousands)? I didn't notice anything about this in the rule book. I imagine this should be a function of the size of the group and the time they have to corrupt them. Also I imagine some disposition modifier.
Also, what if the individuals are already following one deity and the pcs are trying to convert them to another how should I handle the rewards or punishments since they have pissed off one chaos god while bringing glory to another.
Lastly, how do I handle it if the pcs are currently unaligned? So they want to corrupt the population to a chaos god but they are currently unaligned. Seems like they should get some negative modifier.
I'm a little disappointed that this type of thing is overlooked in the rule book since it seems pretty important when gathering resources to conduct a black crusade.
