The Spy, my favourite role

In Town of Salem, the spy is easily the most informed person at any given time. All of his abilities are investigative and since you dont visit anyone at night either, none of the other investigative townies will have reason to accuse you of being evil. 

The Spy's abilities all greatly fit his role's name. At night he can see what the mafia is saying. He cannot see their names though. After every night the spy is shown everyone who was visited by the mafia. And during the day, the spy can read the secret messages people exchange via whispering too!

Of course with all these abilities the spy is a very high priority target for the mafia. An open revelation in chat should be avoided at the start of the game. Only reveal near the beginning if you're about to by lynched, because unlike most, if not all, other roles, the spy can actually prove his innocence! Simply tell someone to whisper to another person and repeat it. If the other innocents are somewhat intelligent, they should vote to save you.

So how does the Spy help win the game? Well first I'd suggest getting allies. Since you see who is visited by the mafia each night, you could try to gain those people's trust by whispering to them. Say that you're innocent and you know that they arent mafia. The more people you win over, the more likely it is for someone you suspect to be lynched.

Next you should of course update your Will every night. Not only does it help you keep track of everyone who was visited by the mafia, but if you die, this information isn't lost. Write down everybody who the mafia visited. Near the end of the game, this should help figure out who actually is a member of the mafia by process of elimination. After all, the mafia wouldn't visit themselves at night...

Of course not every target of the mafia dies at night. You should keep a note of those as well, as they are possibly evil as well. Serial Killers and Arsonists have immunity to the mafia's kills and if anything, need to be found sooner.

If you manage to get the trust of a Transporter, you should make him tell you who he transported at night, so he doesnt end up confusing you by making mafia visit other mafia.

"Playing the Spy card" as I call it, is a trick i came up with that is very effective late-game. If you are a member of the mafia. You can easily gain the trust of the townies by pretending to be a spy. Of course you can't prove it with the whispering method, but people never think of that anyways.

To make townies vote to lynch one another, you simply say who was visited by the mafia, which you know since you did it, and who wasnt. The Townies mostly will believe that half-truth and vote for the person you frame.

That's how I play the Spy. I love that role! I'll leave more ideas or advice for this role later as well, should i think of more.
