Role name: Town Drunk
Description: A drunken war veteran always looking for a brawl.
Alignment: Neutral
Abilities: Visit somebody each night and yell obscenities. Automatically kill anybody that kills you.
Win Condition: Be killed at night after visiting 2 people.
Host Options:
1) Excluded from randoms
2) Cannot be healed
Pros: A role where you have to at first appear low value, and then convince mafia that you are high value in order to die.
Cons: Similar to jester.
Overall effect on the metagame if implemented: Mafia would want to avoid killing you since they would be sacrificing themselves, so you would have to bait them in to attacking you without appearing to be an obvious trap.
Additional comments: I feel it would be fairly difficult to win, since you have to survive at least until the third night, and mafia isn't going to sacrifice themselves to kill you, so anytime you are discovered you basically can't win (very similar to executioner.)
Also, if you are healed then you don't kill the person that attacks you.
