Before the game, I will send out the roles of the cats. Any cat can be a role. If you don't receive a role, your OCs are innocent. Even a kit could be a head killer!

As usual, we have the most common...

Innocents: Normal clanmates. They try to work together and find the Head Killer. Team: Good

The killers... 

Head Killer:  makes decisions with Deputy Killer on who to kill. Innocents and the good team must vote the Head Killer out to win. The Head Killer must kill the Angel in order to win. Team: Evil

Deputy Killer:  helps Head Killer make decisions. I will tell the Head Killer who the Deputy Killer is, and then the two users can text each other and decide, before sending me who to kill. They may also send HOW the cat dies. Team: Evil

The Good team that the killers are looking for:

Angel: Is the cat that the killers are looking for. Has no specific powers. Team: Good

Medicine cat: as usual in the series, the medicine cat heals another clanmate. That healed clanmate will be immune to killing for 1 night. (The medicine cat might heal one of the killers on accident!)Team: Good

Detective: Can find out a Clanmate's role, 1 clanmate per night. Team: Good

Ghostspeaker: Can talk to one of the deceased and ask ONLY for CLUES about the killer. May not ask, "what does the killer's name start and end with" or "what user controls the oc" etc. Team: Good

Other roles:

Jester: Must be voted out to win. Team: Solo

Blackmailer: Can make a clanmate unable to speak for one day. If cats force the blackmailed cat to speak, the cat is only allowed to say, "I am blackmailed." Team: Evil

Veteran: Can choose to be on alert. The cat only has three times to be on alert. Whichever cat comes to the Veteran is killed. (Even the good cats!) Team: Good

Framer: Can choose 1 cat per night to frame. The framed cat will appear as the killer to the  Detective. Team: Evil

Twins: Two cats get this role. If one twin gets killed, the other gets killed too. Team: Good

Head Hunter: You are assigned a cat at the beginning of the game. You must get that cat voted out. If you do, you win. If that cat is killed in any other way besides of voting, you swap to the good team. When on good team, you will be given a target on the Evil team. The targeted cat can't be the Jester or Angel. Team: Solo

Priest: You can choose to throw Moonpool water at any cat during the night. If the cat is on the evil team, they die. If they are NOT on the evil team, YOU die. You can only do this two times. Team: Good

Vengeful Spirit: Vengeance after death. After you are killed, you join the team opposing the team you were killed by. (If killed by the evil team, join the good team, if killed by solo, remain on solo team.) The Vengeful Spirit can curse a member of the team they were killed by each night, forcing them to skip their next vote. This ability only activates if you are killed at night. If you are voted out you do not get to use this ability. Team: Solo 

Elder Warrior: You can choose to reveal yourself at night. This will take effect the next morning, stating that: (cat's name) is the Elder Warrior! After they reveal, their vote counts for 2 votes. But however, they no longer can be healed by the Medicine Cat. Team: Good

Hex Master: You can choose to swap 2 cat roles at night. It will take effect doesn't he follow morning, each cat will be informed of what has happened. The Hex Master can only do this twice. 

Grave Robber: Once someone has died, you can steal their role. If the Twin role is stolen, their Twin will be selected at random. Team: Starts on Good.
