All role PMs will be taken directly from the C9++ Wiki page (link provided above) and will deviate only slightly for some roles. If you have a question about a PM, please look there first it is probably answered there.

I will accept ALL role actions sent to me from any medium.

Should the final two players alive be the Serial Killer and any wolf role, the wolves win.

If there is no clear action sent to me, I will not act, meaning that if I do not receive a clear idea of what you want your role to do, I will not randomize the action in any circumstances, including the wolfkill/sk kill.

The wolfkill is roleblockable ONLY by roleblocking the wolf that is making the kill.

The wolfkill may be made by a wolf that did NOT send me the wolfkill PM, so long as it is specified clearly in the PM.

The wolf roleblocker, if present, may NOT make the wolfkill and roleblock in the same night, even if they are the last wolf alive.

If a 1-shot action is roleblocked, that action is NOT refunded under any circumstance, meaning, the role is basically a vanilla town from thereforth.

Cops will receive a result of either Town (Any town aligned role, the godfather or an investigative immune SK), Anti-town (Any non town-aligned role excepting an investigative immune SK or Godfather) or No Result (The Cop was roleblocked).

If an Investigative Immune SK or Godfather is targeted by a Cop, and is not roleblocked, the Cop will recieve "Town".

Wolves will be PM'ed the names of their partner(s) in their role PM, as well as the role of their partners. This change is because wolves may communicate during the day phase in their factional chat.

Wolves and masons may communicate in their respective private chats, and in no other place.

There is no "flavor" for the nightkills. The Wolfkill(s), SK kill(s), and vigilante kill(s) will all appear the same in my post

The following is a list of things that CANNOT be roleblocked:
The ability of both Wolves and Masons to communicate at night
The Godfather's passive ability to always be checked as "Town" by investigative roles, as well as
Either passive ability that the Serial Killer may choose between: (Investigative Immune OR the 1-shot Bulletproof Vest)

Role action resolution order occurs as follows:
Roleblocking (Roleblocker's ability)
Saving (Doctor's ability)
Killing (Any Killing Role including Wolves, SK or Vigilante)
Investigation (Cop's ability)

If no action was sent by a player and they were roleblocked, they will NOT be told they are roleblocked. If a role has no action (Vanilla Town or Mason) is roleblocked, they will NOT be told they are roleblocked. All night actions, if blocked, will be told that they were roleblocked during the transitional phase.

The following is an incredibly improbable series of resolution events should multiple roleblocking roles target one another:
What happens when Roleblocker A targets Roleblocker B who targets Player C, assuming Player C attempts to use a night action?
Player B is Roleblocked, all other actions take place.
What happens when Roleblocker A targets Roleblocker B who targets Roleblocker C who targets Player D, assuming Player D attempts to use a night action?
Both Roleblocker B and Player D are Roleblocked, all other actions take place.
What happens when Roleblocker A targets Roleblocker B who targets Roleblocker C who targets Roleblocker D who targets Player E, assuming Player E attempts to use a night action?
Roleblocker B and Roleblocker D are Roleblocked, all other actions take place.
As should be apparent, the time at which the PM has been sent does not matter in terms of this resolution.

If Killing Role A and Killing Role B attempt to target Player C, and Doctor D attempts to save Player C, Player C dies (unless Player C is the 1-shot Bulletproof SK who has not yet been shot).
If Killing Role A and Killing Role B attempt to target Player C, and Doctor D and Doctor E attempt to save Player C, Player C lives (If they are the 1-shot Bulletproof SK with their vest in-tact, their vest will remain in-tact)... and so on.

If a Serial Killer is present and chooses 1-shot bulletproof, and they are shot in the night without being saved,
they are notified that their vest has been hit and is no longer of any use. If they are saved in the same night,
then the save takes place before the kill, meaning their vest remains intact.
