Just trowing a few reverse ideas here. Vivor hides a person behind him or suicide? Angel kills target :D, Mason turns converted person into cult Cult turns converted person into a mason. Mimic give his role away. Santa get inverted reports and steal things. Thief Gives away everything he have. Actress Give the guy a suit. Lover wins if target is lynched Lyncher wins if target is alive.
--> I liked the idea but I think this role would be kinda complicated, even if it only worked on reports and saving.
