Second , a bit more achievement .
Vigilante : Shoot the Mafioso who kill you . ( Revenge of Brothers) - I've already added this. It's revenge of justice
General : Draw a game ( Boring Match ) ( I know it is not a good achievement ) Players shouldn't be encouraged not to win a match.
Medium : Guilty on 3 evildoers . (Dead's Informations ) It's actually a good idea.
Trasporter : Win against Mafioso in Stalemate . (Stalemate - Winner ) Sounds good.
Sherrif : Find three mafia in a row ( loop ) ( You are All mafia ) I'm not sure. He already has "find 3 evildoers in a game", but maybe I could add it
Sherrif : Find three Coven in a row ( loop ) ( You are All Coven ! ) Same as above
Transporter : Make arsonist douse himself (It seems my house ) Why not?
Bodyguard :Successfully Guard the Doctor who heal you .( Hero of the doctor of the hero )Sure, I should have added that before
Thanks you very much for the feedback and suggestions! I'll edit the post soon
