A specialized and potent version of luck, you get bonuses for taking risks. If you take an unnecessary risk (GM's option), you get +1D to all rolls. Furthermore, you may reroll any one's on the wild die, but sixes do not explode on rerolls. This only applies when taking excessive risks. For example, if you crouch down behind a wall when a dozen Royal Guardsmen are shooting at you, you don't get the bonus no matter how you got into that mess. If you leap over the wall and charge them guns blazing, you do get the bonus.
