shhh bramble don't tell them!
so it becomes trickster then
It won't get changed but here are some ideas:
Effects from other roles
Fool gets the ability of a paralyzer so he can lock town votes and blitz
New effect:
When the fool visits there are 3 colours of balls.
Red, blue and yellow
The red one will reveal the role of the player that only the fool can see.
The blue one will block the nightaction from the player.
The yellow one will make that player immume at night
The person who gets the ball doesn't get a system message of what ball he gets.
Balls are given out randomly
( just a bit of brain storming )
You can change the idea if you want a bit.
