The consequences of a failed Save should be obvious and telegraphed. Remember that Saves should only occur when a player wants to avoid a negative outcome.

Some options for consequences are:

• Damage: ranging from d4 to d20. d4 is minor, d6 is dangerous. d8 is enough to seriously injure a Level 1 character. d20 damage is rare but deadly.
• Condition: Exhausted or Frightened are good options.
• Lost time: Each action takes a Turn. Lost time can burn torches and cause random encounter rolls.
• Loss of random item: Roll d6 for inventory slot.
• Mark usage on item: Mark 1-3 usage dots.
