After a player describes a move they want to make during the game, you might decide an action roll is necessary to determine how the scene progresses. Use this guide to determine what to present the player, choosing whichever option best fits the situation:

• Let the PC guarantee success in exchange for a consequence. If there is an opportunity for an interesting consequence, offer the player that outcome in exchange for performing the move without a roll; should they agree, the PC succeeds and you narrate the repercussions. For example, rather than rolling to see if a PC can jump from one roof to another, you might allow them to automatically succeed in exchange for being noticed by bystanders on the street beneath them.
• Establish the stakes. If a move is particularly difficult or dangerous and offers interesting consequences for success or failure, establish the stakes for the roll so that the player knows what to expect. Once everyone is aligned, ask the player to roll and shape the fiction around the results. For example, you can inform a player whose wants their PC to leap across rooftops that they’ll jump without alerting anyone on a success, but a failure will mean they crash into the streets below, suffering heavy injuries. This empowers the player to take informed risks and lean into the fiction.
• Make clear any guaranteed consequences. If a move is particularly difficult or dangerous, and if it will certainly have repercussions regardless of whether the PC succeeds or not, tell the player about those repercussions before the move occurs. If the player wishes to proceed with the move, ask them to roll and narrate the consequences without compromising on your repercussions. For example, you might tell a player who wants their PC to jump from the roof of a burning building to safety that the roof will collapse in the attempt. Even if the roll succeeds spectacularly, narrate the building groaning and collapsing in on itself, preventing anyone after from performing the same escape.
