After you roll and see your result, but before you know the outcome of the contest, you can spend one of your extra chances to reroll your entire dice pool. You must take the new result of the new dice pool regardless of the new outcome.
This constellation may be taken multiple times, and each time it is taken the supply of extra chances increases by two.
First time: 2 rerolls; Second time taking: 4 rerolls; etc.
Your extra chances refresh at the start of each session with your elemental energy unless otherwise stated by the GM.
