Parity Cop
Your role is Parity Cop
Your alignment is Town Investigative
You are a devoted member of the police force, deducing the general trustworthiness of civilians based on previous familiar faces.
Once only used as an assistance to crime cases, you now however, since the Mafia invasion, have decided to use your excellent deduction to your advantage, judging who to trust.
Every night you have the ability to compare 1 town member to a past town member you investigated the previous night.
You will deduce whether they share the same alignment or not from similar or different reactions.
You may not compare yourself to others because of your reluctance to expose your jealousy, and the Mayor as he is too busy to have a nice chat.
You win with the Town
You win with Survivors
You must kill the Mafia
You must kill Arsonists
You must kill Witches
You must kill Serial Killers
You must kill Stalkers
You must kill Bombers
You may spare anyone else.
