Hazard Clocks and Pressure Mechanics

Abstract

Hazard clocks replace single-roll random encounter tables with a stack of concurrent, independently advancing counters. Each clock tracks a distinct threat category. Player choices — pace, caution, delay, noise — advance or suppress each clock. When any clock fills, it triggers a concrete consequence rather than a single rolled event.

The result is travel and exploration that feels genuinely risky without requiring constant combat interruptions.


The Core Model

A hazard clock has three properties:

  1. Domain: what threat category it tracks (see clock menu below).
  2. Capacity: how many segments before it triggers (typically 4 or 6).
  3. Advance trigger: what player actions or conditions push it forward.

Multiple clocks run simultaneously and advance at different rates. A stealthy party moving slowly might suppress Attention entirely while rapidly filling Supply.


Standard Clock Menu

These four clocks cover most expedition play. Add or remove based on setting.

Clock What It Tracks Default Advance Rate
Exposure Weather fatigue, radiation, environmental hazard 1 segment per turn outdoors/in hazard zone
Attention Faction awareness, noise, detection, patrols 1 segment per loud action, shortcut through danger zone, or missed stealth window
Supply Food, water, light, ammo, battery, fuel 1 segment per rest phase; 2 per missed forage/ration step
Stability Route collapse, political change, environmental shift 1 segment per delayed or off-route travel; 1 per in-world time unit

Pace modifier: fast pace advances Attention +1 and Exposure +1 per turn. Slow pace suppresses Attention −1 but costs an extra Supply segment.


Campaign-Scale Clocks

The same model scales to between-session faction and setting pressure.

Clock Domain Trigger
Governance Legitimacy collapse, succession, corruption crackdowns Faction takes unchallenged control of key site or institution
Security Raid militarization, patrol density, insurgent response Party actions that visibly destabilize a faction
Infrastructure Roads, gates, power grids, supply lines Extended absence, siege condition, or enemy advance
Belief Cult growth, reform panic, ideological schism Public events, prophecy triggers, or symbolic desecration

Advance campaign clocks once per world-state turn. Publish a visible in-world sign when any clock advances.


Implementation Variants

Necropraxis Hazard Die (d6 Clock)

Roll a hazard die each turn. On a 1, an encounter occurs. On a 2, a hazard event (not necessarily a fight). Other results are quiet or partial signals. Simple, fast, low bookkeeping.

Hex Flower Pressure Matrix (Running Silent)

Clocks are represented spatially on a 2d6 hex flower. Players sit in a region (Quiet, Clock, Surge, Cross) that determines ambient complication flavor. Advance by rolling and moving. Hitting certain hexes triggers region-specific consequences. Good for session-pacing in mission-based play.

Stacked Domain Clocks (Necropraxis Extended)

Run all four standard clocks simultaneously. Each uses a d6 segment track. Referee advances clocks at the end of each turn based on the party's declared actions that turn. Any clock reaching 6 triggers immediately. Used in expedition-heavy campaigns where supply and detection pressure coexist.

Domain-Turn Model (Campaign Scaffold)

Each active faction, environment, and mystery runs one clock per session. After each session, roll or choose one escalation per clock. Record one visible sign and one hidden implication. Keeps the world moving without writing narrative outcomes.


Advance/Suppress Matrix

Use this to adjudicate clock advancement at the table without negotiation.

Player Action Exposure Attention Supply Stability
Fast pace +1 +1 0 0
Slow pace −1 −1 +1 0
Stealth move 0 −1 0 0
Loud action / combat 0 +2 0 +1
Short rest / camp 0 +1 +1 0
Full rest (full night) −1 0 +2 0
Forage success 0 0 −1 0
Route deviation 0 0 0 +1
In covered shelter −2 0 0 0

Design Principles

  • Clocks reward caution without mandating it. Fast play remains viable — just riskier.
  • Clocks externalize consequences. Players can see what they are accumulating toward.
  • Multiple simultaneous clocks create genuine dilemmas. Reducing Exposure may require rest, which advances Supply and Attention.
  • Clocks replace pseudo-randomness. Instead of arbitrary "you are attacked now," filling a clock creates a narrative inevitability.

Failure Modes

  • Too many clocks: above four simultaneous clocks the system becomes bookkeeping overhead. Use only the clocks that matter for the current scenario.
  • Undifferentiated advancement: if every action advances every clock, the pressure becomes noise. Define advance conditions tightly.
  • No visible signs: clocks that fill silently produce no tension. Give players visible telltale signals before a clock triggers (patrol sighted, rations running low, faction graffiti on the wall).
