My candies prevent them from becoming cultists but not undead. Sorry.
So, if I understand right.
People who have 'undead status' are people you need dead before you can win, yes?
Your candies/protection do not prevent people from developing the status that means you need them dead before you can win, but would prevent the person from becoming a cultist.
Are you certain you need 'undead status' folks dead if they are not cultists?
If you have a way to separate 'undead status' from 'is in the cult/is auto inducted into the cult/does not matter for your wincon requirement' that's pretty useful in my eyes.
I don't particularly intend to side with you over the cult you say exists. I expect to side with the winner, and figure one of you must kill the other - really I figured you're confused and are actually an undead hunter who thinks undead have to be in a cult, the status has to be contagious, whatever; your claims are very different from the role info I have about the various 1-shots I can use. I can avoid adding new 'undead status' folks to the game while you're in it (or I can try to flood the game with more of them; neither seems especially useful to me especially before I know if you or the 'cult' would take the other out) and I figure/figured you'd chew at me until I'm dead and you're sure that didn't solve your problem (right now, my death only prevents me from using abilities that could add new undead; something I'm willing to do while alive, at least for a reasonable amount of time - but I can't be who you're looking for. I don't have the status and I don't convert alignment).
However, if you have a way to easily sever 'undead status' from 'becomes cultist' so I can make undead that you don't have to worry about, that's fine with me, makes everything easier for me. Probably makes things more difficult for your undead cultist, sorry whomever that is, but it's probably not worse for you to have that severed but created than it would be for it to not be created.
You and your current undead status folks have some sort of war, it seems to me. I'll definitely support the winner, and I don't care who it is. If I can slip out of being involved, by having candy and using those one-shots only on folks who had the chance to eat your candy, that gives me closer to 'this undead-hunter-thing is resolved' and I like that idea, if that's how it works.
