Your job is simple (or hard depending on how you see it and how the settings are) you must either: abduct (kill) a minimum of 1 of each team, or survive to the end to win...
Let me explain.
This role's requirements would change depending on how many Impostors/Neutrals you pick for your game (So the lowest you can abduct is 1 imp, and 1 crew. - If Neutrals are turned on, you would HAVE to abduct 1 Neutral too) - It would work just like with Scavenger, anyone you abduct goes outside the map.
You're likely also thinking "How would I know who is who?" Everyone's name is coloured according to their team (not role, just team - so all imps would be red, all neutrals are grey, and all crewmates are cyan) and each time you're "full" with one of the requirements (E.G. you've abducted 3 crewmates) it will show a corresponding colour by your name to show "You don't need to go for these guys anymore" (Or all those names for that specific team turn to default white)
Now you're probably thinking "How would you win if for example, there's 3 imps, but one of the neutrals kill an imp?" that's why there's a second way to win, if you survive to the end, you win alongside others (basically you're a deadly Opportunist)
And now the big question; if it's just 1 imp, and 1 crew, wouldn't it be too easy to finish the game just abducting 2 people? Well actually, it's not a solo win. Once you've hit your target, you win regardless of what happens next (You could go finish off the imps, you could help the imps win, you can abduct a terrorist who's finished tasks, whatever you want!), so you can die and you'll still win (bit like how if Phantom dies and completes all their tasks, they win regardless of which other team wins), but if you don't hit your target, you MUST survive to win
Options set by host
Imp abductions: 1/2/3
Neutral abductions: 1/2/3
Crew abductions: 1/2/3
Rolehole/Noah's Ark counts as: Neutral/Nothing (Same concept used with sidekicks' Jackal/Crew/Nothing)
