So basically I am doing a whodunnit, which;
Starts off at an ugly sweater party, and the players can interact a bit, but one of them have been previously chosen as the murderer.
The murderer will choose them selves who they'd like to kill off.
When the death is announced, the murderer will leave 4 clues. 2 of them must be what they have on them, and 2 can be what another person looks like. The murderer can frame somebody if they wish. The clues come in 5 categories;
* Fabric; a bit of loose clothes that fell off them. Ex. Blue fabric if you have a blue jumper.
* Color/Accessory; some accessories that fell off them. Ex. Black Color/Accessory if you have a black hat.
* Shoes; Maybe one of their shoes fell off running away from the body. Ex. Brown shoes if you have brown shoes. Note that the murderer will still have shoes on, but the shoe will be identical to theirs.
* Hair; a bit of loose hair that fell off. Ex. Blond hair if you have blonde hair.
* Misc; a miscellaneous item that might depict to the type of character or gender. Ex. Lipstick would point to girls, and pocket watches might point to elderly. The only 3 miscellaneous items are lipstick, pocket watch and carrot.
But the killer can always frame someone, like this;
Blue fabric (NOT THEIRS
Blonde hair (NOT THEIRS)
Black shoes
Pencil
Let's say he actually had white or red fabric and brown hair. This would throw the suspicion off him and onto someone else, but the pencil might be a standout based on his character.
You do not have to ALWAYS have hair in it or ALWAYS have black shoes. You could go like this;
Blue fabric
Red fabric
Blonde hair
Red hair
Now, picking 2 hairs at a time would make it obvious someone was being framed, but this is just an example. You could go off and make them all fabrics too.
If the murderer is killed off early, another murderer will be picked, and another if they are, and another, and so on, and it will end if there are 2 people left. If the murderer is within that final 2, the team of murderers win, but if there are only 2 survivors/the last murderer was caught, survivors win.
Some characters might have storylines. The players will be told of this and will gain 10 coins if they do. Gain 60 coins and you can go to a shop and you can get the "Seer" ability; be able to see whether or not someone is suspicious or not. 40% chance of seeing an innocent and the murderer, or seeing a murderer as an innocent. If the murderer goes to the shop, he gets the "Hidden" ability; the ability to give his next 4 clues and have none of them have to look like him. Or, in other words, he can completely frame someone else without having any of the clues linked to him.

If you have any questions, please be free to ask!
