@ the necro mechanic:
It says "for each dead player in the necro's control, he gets a kill". This seems to mean the necro has to target a dead body every Night to add it to his horde. Could mean not that, who knows, let's assume it does.
Assume necro is sole scum NK, and that necro can kill the same night it targets. 12, lynch to 11, NK to 10, lynch to 9, NK to 7, lynch to 6, NK to 3. If it can't kill the night it targets, 12, 11, 11, 10, 9, 8, 6 which is mylo? If it doesn't have to target bodies, then it's 12, 11, 10, 9, 6 which is mylo/lylo depending on scumteam.
Assume necro is indy kill and that it can kill the same Night it targets. 12, lynch to 11, NK to 9, lynch to 8, NK to 5lylo/PD. If it can't kill the Night it targets, 12, 11, 10, 9, 7, 6lylo. If it doesn't have to target, 12, 11, 9, 8, 4 which is probably PD.
Necro is likely the sole scumkill IMO. Probably with a single partner, who may or may not get a 1-NK if necro dies. And of course none of this accounts for our PRs.
