Mafia could be killed as well, Blade was fairly close Day Two and Three. Even Day One at one point.
I gave some consideration to a minimum level which would warrant no kills at all, but didn't come up with any actual rule since there is never a game in which every player is safe from being called a lurker.
I was going to "leave town" at the start of Day Four though, so if Blade had been killed(or either mafia lynched) or if there had been a No Lynch at some point, it would have turned into a normal game other than the voting changes.
Also, I could have been "lynched" in which case no more kills. It would still have gone to Night unless lynching me would give mafia the win, in which case Night would be skipped.
The idea was an extra kill would both decrease the amount of mislynches mafia need for a win as well as reduce the number of mislynches town wastes on lurkers. There were three reasons for having the death at end of Day rather than a second Night kill. Mafia and the Mason Recruiter wouldn't waste an action, Mafia's kill would be clear, and a Bodyguard death wouldn't cause extra confusion.
