Flashback

Flashback is a system of retroactive addition to the game's narrative. You can spend 20 XP to activate a flashback, a scene in the past that had already happened. For example if you're now stuck in a jail cell, you could flashback back to before you were caught and roleplay having gotten a lockpick. Or maybe you could roleplay saying a final goodbye to an ally fallen in battle. It is aimed at retroactively changing the whims of fate.

Do note that use of Flashback does have to be approved by the GM and that you do need to play out the scenario.
