I have noticed in throne of lies, a big thing is the Convert mechanics I believe that these gameplay options are gonna be really unique however it will require a lot of balancing in order to make it work.
Firstly Because you have not specified what happens when the mastermind and The Assassin die, so I believe at the moment that when 1 dies a lower rank swaps their role for the dead 1. for example when the Assassin dies a non-killing black rose class changes to become the assassin so the black rose can still kill, or an assassin becomes a mastermind so they will still be able to get some members
however, this can be a problem because if this happens a lot the grave will be filled with nothing but assassins and masterminds making the blue dragon unable to tell what Role’s alive and what’s dead anymore
my idea was this when a role dies that was changed from its original, not including the masterminds Convert ability so it stills shows their evil role when they die not their blue dragon role.
it will instead show what they were when they died
for example, an assassin was killed so the newly appointed Servant is now changed to the assassin, however, he dies but when he dies he is shown to be a servant but with something like a symbol next to it so the blue dragon knows that he was a servant but he was changed into an Assassin or an assassin changed into a mastermind
this method could also work with the cult members so when one dies it shows its original class, however it would need to be a different symbol if a cult member was changed into the cult leader, so it still shows his starting class but it tells us that he was a cult leader, not a normal cult member
doing this method would make the blue dragon a lot less confused when these types of roles are shown in the grave so it’s not just cults and assassins in the grave.
