When you indulge your vice, you clear some stress from your character's stress track. Say how your character indulges their vice, including which purveyor of vice they use to satisfy their needs. This indulgence takes time, so it can only be done when the crew has downtime. Alternately, you may choose to release your character to be "lost in their vice" during a game session, allowing them to indulge off-camera while you play a different PC. A gang member, friend, or contact of the crew might be created as an alternate character to play, thus fleshing out the landscape of PCs.

You roll to find out how much stress relief your character receives. A vice roll is like a resistance roll in reverse—rather than gaining stress levels, you clear stress levels. The effectiveness of your indulgence depends upon your character's worst attribute rating. It's their weakest quality (Insight, Prowess, or Resolve) that is most in thrall to vice.

Make an attribute roll using your character's lowest attribute rating (if there's a tie, that's fine—simply use that rating). Clear stress equal to the highest die result.
