So I do not know if someone has already suggested this in the past, but here is my idea.
The Jester will many times, lose the game due to roles like investigator catching them early on. I figured the best way to help a Jester is for him to have a "Fake evidence" ability
Example:
Attributes:
- Plant fake evidence on yourself
- While framing yourself, town members will see you as a mafia member for 1 night
- Can only be done 3 times.
I think this would work well because often I find myself (and other players) struggling to win as a jester. Jester is a class that can be easily called out and has no real abilities to achieve its goal. Similar to abilities from roles like Jailor, Veteran, Vigilante, and Doctor; the Jester needs to use his limited framed wisely (At times when the town suspects them and predicts being investigated)
Also I am not sure how escort would work with this, I assume the best way would be for escort to just simply stop the jester from framing themselves.
