- The Chemist's role is almost entirely useless, as far as I can tell, except maybe in some lylo-like situations where delaying a lynch by one day is enough to win. You may prolong a mafia member's life for one day but in return you're probably giving out confirmed townies to protect with the pharmacist.
- The Drugger doesn't seem excessively powerful - it's like a nightkill but with a more limited scope. He can only choose between the group of 3 players the town finds most scummy, and the pharmacist can opt out of being gassed if he roleclaims. In addition in some cases he could just be making a lynch happen one night early.
- The Vaccinated Townie seems overpowered. He can only die to a one-shot role that may or may not be in the game, and which really
- The Sealer would cause serious issues if he were in the same compound as the Drugger - the mafia has no kill. In addition he's easily confirmable by any PR, and could claim fairly safely due to being able to defend himself from knife attacks.
- The Backup Pharmacist is probably unnecessary. Getting the pharmacist, who can claim freely once the Knifer is out of the picture AND resist lynches, killed is already a tough task for the mafia.
So you could have a game with up to 3 virtually invincible confirmed townies and no mafiakill.
