After much thought, I have decided to post this early so that players can see and critique it before Wednesday's session.
Fabletop B-ball rules
If you have the ball at any point during your turn, you get two actions. So if you have the ball at the start of your turn and pass it, you can take another action; likewise if your first action is to steal the ball from an opponent and you succeed, you gain a second action. Attacking the other team normally is allowed, but you can't attack while you are holding the ball.
The court is split into four zones by three Dividing lines: the half court line and the two three-point lines. The dividing lines serve as a crude measure of distance, although you can still move wherever you want if you aren't holding the ball.
There are four specialized actions you can perform on your turn:
Shoot - roll Might. By default you need one star to succeed, plus one additional star for each dividing line the shot has to cross.
Pass - roll Might. The number of stars you need to succeed is equal to the number of dividing lines the pass crosses (if your pass crosses no dividing lines, it still needs 1 star to succeed). If an opponent is between you and the player you are passing to, they can roll agility and intercept the pass if their roll is higher than your Might roll.
Dribble - roll Agility. You need one star to succeed. You can only dribble the ball across one dividing line per action, no matter how high your roll is. If your move takes you near an opposing player, they can roll agility and steal the ball if their roll is higher than yours. You can only dribble in a straight line: if you want to dribble to the side and then forward to avoid an opposing player, you need to use two actions.
Steal the ball - move next to whoever has the ball and roll Agility against them. If you succeed, you get the ball.
For each of these actions, you can add any bonus skills you can justify.
Just one random act of violence can brighten your day. Especially if it involves explosives.
