Campaign Clocks

GM Reference

A campaign clock is any visible or invisible measure of pressure. It tracks what happens if the players delay, split their focus, or spend weeks in safety. Use clocks to make the world feel alive without forcing every problem into a combat encounter.

Days
Travel, wounds, rituals, supplies
Weeks
Investigations, politics, downtime
Months
Trade, seasons, armies, debts
Hidden
Cult plans, rival schemes, rot beneath the floorboards

What to Track

  • Threat progress toward a visible goal
  • Seasonal shifts in travel, food, weather, or politics
  • Deadlines such as court dates, festivals, taxes, or treaties
  • Recovery windows for allies, factions, and settlements
  • Rival adventurers moving on the same opportunity
  • Escalation of a monster, plague, rebellion, or cult
  • The decay of a lead, witness, map, or borrowed advantage
  • Anything the players would feel if they arrived too late

A Simple Clock Method

  1. Name the pressure. "The baron closes the passes," "the cult opens the gate," or "winter freezes the ford."
  2. Pick the scale. Use 4 steps for quick tension, 6 for standard arcs, and 8 for major campaign threats.
  3. Decide what advances it. Time, failed rolls, ignored signs, public mistakes, or enemy success.
  4. Decide what players can do about it. Delay it, conceal it, break an ally loose, or spend resources to slow it down.
  5. Show the consequences. A clock matters because the world changes when it fills.
Clock Type Best Use Example
VisibleOpen urgency that players can plan aroundThe coronation is in 10 days
HiddenThreats the party senses but cannot fully measureThe necromancer completes one stage per grave robbed
SeasonalTravel, economy, and kingdom playSpring thaw opens the mountain road
FactionPolitical rivalry and off-screen motionThe guild buys three council votes

When to Reveal the Clock

Reveal it when you want informed player choice. Hide it when uncertainty is part of the tension. Either way, the players should be able to notice signs: rumors, troop movement, empty shelves, worsening omens, missed messengers, or frightened towns.

Rule of thumb: if a clock can ruin the campaign without warning, it should leave tracks. Surprise is fine. Pure gotcha timing is not.
