Motherfucking Snakes!
If you are attacked by a snake, the SM will roll 1 die and consult the following table.
1: The snake tries to bite you. Lose 1 point of Guts as you swat it away.
2: The snake is poised to strike. Lose 1 point of Nerve as you throw something at it.
3: The snake falls in your hair or crawls up your pants leg. Lose 1 point of Cool as you totally flip out because, dude, it's a goddamned snake.
4: The snake presents you with a logic puzzle, such as Sudoku or a rubik's cube. Lose 1 point of Wits beating this insidious game.
5: There's someone bigger or tougher than you nearby. Lose 1 point of Charm as you convince them to go deal with that fucking snake.
6: Reroll and double all point values lost; you stumbled onto a lot of motherfucking snakes. Reroll and double every time the die comes up 6.
Once you subtract the point or points from your relevant trait, you have dealt with the snake (for now). If a trait is at 0 and you are asked to subtract points from it, the snake kills you.
Example: we're in AGS and my character, a husband trying to save his marriage, sees his wife and his kid being accosted by a drunken and terrified passenger. He tries to pull the passenger off them. This is a Guts roll and my character has a Guts of 5. He rolls 1, 1, 3, 4, 5: one success and two snakes. He is attacked by a snake.
The GM rolls a 6 on the Motherfucking Snakes table. He rerolls and gets a 3: two snakes land in my hair. I lose 2 Cool points getting them out. This reduces my Cool from 3 to 1. If my Cool (or any other trait) is reduced below 0, the snakes kill me.
