Between relaxed time and real time resides this mode of play. Like relaxed time, the concept of using potential to determine how much and how well an actor can do things is used, but no initiative order is used. In addition, the players can share potential through a shared potential pool.
This mode is well-suited for when there is a limit to how much the players can do before something might happen that would trigger real time. Like the name alludes, it comes in handy when the game master wants to signal a transition from the calm and safe to the tense and thrilling.
