On the cultists:
Still worried that the game will become too warped with them around. Cults hog attention worse than the mafia does. As such, the town can easily forget the dopps just to go cult hunting.
So I'm VERY worried about a fully recruiting cult.
Vampire:
VERY random version of a cult, ranging from 1-night losing to slaughtering everyone (if several vamps are made).
Alternative: The vampire MUST feed off a player every night. To do so, they have two options:
1. Feed: This option kills the victim. Works on all players.
2. Prepare: Prepared the victim for conversion by partial feeding. No effect is shown.
If you Feed, you must do it every night to sustain yourself. It is a physical action. If blocked by a bodyguard, you feed off the bodyguard. If you are actually stopped (roleblock, guardian, ext.) you die.
If you Prepare a victim one night, you MUST return to them the next night. Then, you finish feeding from them, if they are human, you then perform a ritual turning them into a vampire. The new vampire retains their old powers but has the same feeding requirements and new win condition you do.
Note that if they are not human (cult, dopp, alien) they die. If they are not alive for the second night or you are somehow stopped from reaching them, you die.
To win, at least one vampire must exist by the end of the game. This goes for the original and newly made vampires (who lose their old win requirements). This does not get in the way of other requirements (including the watcher)
Result: a Survivor that is a hybrid SK/recuiter. To live they MUST kill or attempt a recruit. Recruiting helps ensure victory but is risky since you cannot switch targets for two nights.
Leaning: Slightly anti-town due to the Survive feature and the wish to kill those that probably will not be affected by the guardian. Can be played pro-town if they rely on conversion (since it will kill dopps/cults but not humans).
Warewolf:
One change: Use the alternative version and make the ability uncontrollable even after the first time. Thus it turns into something like a Crazy doc role (sometimes kills, sometimes uses power).
Robot:
That's just a Bulletproof Survivor. There's not much really to it that the Alien Survivor doesn't have.
I'll add one, pulled from Religion Mafia
Virus maker.
Each night, you will infect a player with a virus. The virus leaves the person sick for one night (roleblocked) in a way similar to the appearance of other roleblockers (the 'block message' matches other roleblock messages). After that, the virus survives for one day then is killed by the player's antibodies.
At the end of the following day, whoever the infected player votes for becomes infected with the same effects. If the person voted on is lynched or dies in another fashion, the virus dies in the new host. If the old host is lynched but voted on another, the virus is transferred before the lynch.
For the virus maker to win, over half the town must be infected by an active virus when the game ends.
