Every now and then the dice may not work for you. That's why Savage Worlds gives you, the player, a little control over your hero's fate.

Every player starts each game session with three “Bennies” (American slang for “benefits”), represented by gaming stones or other tokens that signify a little bit of good luck or fate. The Game Master may also give you more Bennies for great roleplaying, overcoming major obstacles, or even entertaining everyone with an outlandish action, side-splitting comment, or other memorable act. (Tips for awarding Bennies can be found in the Game Master’s section on page 145.)

You can use Bennies to reroll any Trait test. Make the entire roll from scratch. If you're firing three shots on full-auto and don't like the results, pick up all three dice and your Wild Die and roll again. You can keep spending Bennies and rerolling as long as you like, and take the best of your attempts. If you roll a 5, for example, and a Benny gets you a 4, keep the original 5 instead.

Bennies cannot be spent on tables, damage rolls (unless a character has the No Mercy Edge), or any other roll that isn't a Trait roll.

Soak Rolls: Bennies can also be used to save your bacon from deadly attacks. Choose carefully where you spend them! See Damage for complete information on how to make Soak rolls.
