That baws icon.

he can only overturn one person's vote, therefore, he can mess up maf kills

why would meddler mess up mafia's kill ?
and you never answered: does he overturn just the person's vote or the whole meeting's vote

That's the point. Meddler can fucked up mafia kills or culting/masoning. And they can choose no one like what you said. they can also change santa's gift, jailer/gator's kill, angel's save and other actions

so they'll know the maf then. i mean, how does that work exactly, without giving the role away. for example, the only two town roles that double-visit are baker and santa, otherwise they'll know it's maf. for example, baker is the only role that can't pick nobody. santa will be obvious because you'll have to pick a bread/gun/whatever (unless fabricator is in setup, but even in that scenario, you could choose nobody) well, that brings me to this: if you make the person not use their action (can you ?) then if they're in a meeting, say cult or mafia where there are three of them, then it would only overturn that person's vote so the other two would have majority, correct ? also, would they other person(s) in the meeting see the vote change ?

yep. they can see double visits

what about dual visiting roles ? do they see both ?

That's the point in making the meddler not attend mafia meetings, they can change what their partners chooses without knowing. LOL. They can only see the night action taken by the player chosen, only that and nothing else. for example "The person you chose picked Player A" something like that. Meddler can also accidentally change what their mafia partner choose in meetings

can he make maf accidentally override to themselves ? does he know the maf ? also if he picks a mort or an amn would they still be able to work ? mort being a detective, amn being mimic. OH, and also, does he see who else is in the meeting ? does he see the convos that take place ? or is it just "PlayerX is using their night action on PlayerY and PlayerZ" Override ? Yes/NO

i like it

override - can change who that person chose.

What do you mean by override? Needs more details? Override with what, for that matter?

not bad

Plussed ^_^ I think this is rather unique

Not bad, I guess. Kind of like a single-person driver.
