best setup 2018

Werewolves [6]
Every round, they will collectively decide on someone to eat. They cannot eat themselves, each other, or anyone who is already dead. After they eat someone, everyone else votes for who they think the werewolves are. Then, whoever gets the most votes is out, and we find out their role. The game will end when either all the werewolves or all the others are dead. Werewolves also cannot eat spirits. If they eat a revenger, they will die, and if they eat a poison pin, they will be poisoned. If they are eliminated, they cannot vote.

Seers [3]
Every round, they will decide whose role to see. They cannot tell anyone else their findings, however, they are very useful for knowing who to vote for and who not to. If they are eliminated, they can vote, but only if they have not seen a werewolf.

Protectors [2]
Every round, they will each pick one player to protect. They cannot protect themselves or each other. Anyone they protect cannot be eaten, voted for, revenged, or poisoned for one round. They can defend the same person a second time, but they cannot do so in the very next round, and after the second time, they cannot defend that person again. If they are eliminated, they can vote.

Revengers [2]
Their powers will not come into play until they are eliminated. If they are eaten, the last werewolf to vote for them will die unless they are protected or put to sleep. If they are voted out, the last player to vote for them will die unless they are protected, put to sleep, the other revenger, or a spirit. If they are poisoned, when they die after three turns, the poison pin will die. If they are eliminated, they can vote.

Psychic [1]
They know everyone's roles. Like the seers, they cannot inform anyone of these roles, but they are very useful for knowing who to vote for and who not to. If they are eliminated, they cannot vote.

Sandman [1]
Every round, they will pick one player to put to sleep. They cannot put themselves to sleep. Like defended players, any player put to sleep cannot be eaten, voted for, revenged, or poisoned, but they also cannot vote for one round. If they are eliminated, they can vote.

Spirits [2]
They cannot be eaten or revenged. However, they can be voted out and poisoned. If they are eliminated, they can vote.

Immortals [2]
They cannot be voted out. However, they can be eaten, revenged, and poisoned. If they are eliminated, they can vote.

Spies [2]
They will each pick a different role PT to be added to at the beginning of the game. However, if they post in the role PT, they will be disqualified. If they are eliminated, they cannot vote.

Double Voters [2]
They can vote twice: once on the main thread, and once in their PT. They cannot vote for each other (not that they would need to). Their votes will be added to the count in the main thread. If they are eliminated, they can vote.

Poison Pin [1]
They can poison someone at any point in the game. They cannot poison themselves. Whoever is poisoned will not know they are poisoned until three rounds later, when they die. However, they can only use their power twice in the entire game, so they must use it wisely. I suggest using it on someone you think is a werewolf. They also cannot use their power again until whoever they last poisoned is either dead or healed. If they are eaten, the last werewolf to vote for them will be poisoned. If they are eliminated, they can vote.

Healers [2]
Every round, they will each pick someone to heal. Their heal will have no effect unless the player one of them chooses to heal was going to be eaten that round. Then they will be saved. Also, if they heal a poisoned player, they will be cured of poison. They cannot heal themselves or each other, nor can they saved someone from being voted out or revenged. If they are eliminated, they can vote.

Self-Sacrificer [1]
Every round, they will be informed of who is going to be eaten before it happens. Then they can choose if they want to die in their place. They are advised to do this if they think an important role is going to be eaten. If they are eliminated, they can vote.
