I think old mafia players already know this role but I will create my variant of it so it fits this game:
Role name: Fearless Vigilante/Daytime vigilante
Description: You are a Noctiphobic vigilante who can only kill during the day.
Alignment: Town(Power/Advanced)
Abilities: You can pull out your gun and kill someone while in the day chat. Type -kill to activate your ability and choose your target. You can only use this ability before someone is voted to be sent to trial/Unrestricted(Ballot). The role is only revealed to you and the person you killed enters dead chat. The person's role is revealed to town the following day. You can use this ability only once, choose wisely.
Win condition: Lynch every criminal and evildoer.
Dead person's death description: He was found dead in the forum of voting. He was killed by a high-caliber gun.
Special Attributes;
- - Automatically kill all role-blockers.
When investigated by sheriff: Your target is not suspicious.
When investigated by investigator: Your target is an arsenal of weapons. He may be Jailor, Vigilante or Mafioso.
When investigator detects exact role: Your target is Daytime Vigilante.
Host options: Is revealed as Daytime Vigilante (and cannot be healed at nights)
Host options: Kills role-blockers.
Host options: Is auto-revealed to Jailor if he gets jailed. (Jailor doesn't die)
Pros: Mysterious fun role, killing role.
Cons: Can be hard to choose whether to use or not the ability.
Overall effect on the metagame if implemented: Town will doubt people more, will make it more interesting.
Additional comments: Can be a great combination for the Godfather to claim Daytime Vigilante, having killed a blackmailed person. Can be a great combination in a non-mylo/lylo situation, killing between Ccs to know who is lying and get one mafia or two at once.
PS: It's not a typo, it's Noctiphobic. Nyctophobic is fearing the dark, Noctiphobic is fearing the night.
