A run begins with a set of starting resources while rooms, rewards or combinations change. Failure resets the run; each design decides which forms of progress persist outside it.

Show the loop

Enter a new area with few resources
Make one tradeoff in a fight or an event
Use the new ability to change the next encounter
Restart immediately, keeping only memory of the route
