Monster Doctrine (GM Reference)

This page defines how Monsters and Creatures function in Kaernest.

It applies to: - beasts, - horrors, - supernatural entities, - aberrations, - non-humanoid threats, - and creatures that do not meaningfully participate in society.

It does not replace NPC Doctrine.
Monsters are not people-driven threats.

They are problems, pressures, and forces.


Core Distinction: NPCs vs Monsters

NPCs are people.
Monsters are situations.

NPCs apply pressure through: - memory, - legitimacy, - escalation, - consequence over time.

Monsters apply pressure through: - danger, - disruption, - territory, - instinct, - inhuman persistence.

Do not run monsters as silent NPCs.
Do not run NPCs as disposable monsters.


Core Assumptions

  • Monsters use the same core resolution system as PCs.
  • Monsters may use the same harm tracks, but are not required to mirror PC anatomy or psychology.
  • Monsters do not have Effort.
  • Monsters do not use Flashbacks.
  • Monsters do not engage in social escalation unless explicitly stated.

Monsters are dangerous because of what they are, not because they are optimized.


Monsters Are Not Mini-PCs

Monsters are not built for parity or fairness.

Key differences: - Monsters may ignore skills that do not apply to them. - Monsters may replace rolls with static values more often. - Monsters may act on instinct, pattern, or compulsion. - Monsters may have asymmetric defenses or vulnerabilities. - Monsters may break action economy expectations.

Monsters should feel: - predictable once understood, - terrifying before they are understood, - solvable through observation, not optimization.


Monster Purpose

Every monster should answer at least one of the following:

  • What territory does it claim?
  • What does it hunt, consume, or corrupt?
  • What behavior does it enforce?
  • What does it make unsafe?

If a creature exists only to be fought, it is probably an NPC threat in disguise.


Attributes & Skills (Monster Defaults)

Attributes

  • Monsters use attributes when it clarifies interaction.
  • Attributes may exceed typical humanoid limits.
  • Monsters may lack attributes entirely where irrelevant.
  • Negative attributes are acceptable and expected.

Example: - A massive predator may have no meaningful Presence. - An incorporeal horror may have no Brawn.


Skills

Monsters do not need full skill lists.

Use skills only when: - the monster contests a PC directly, - the skill meaningfully differentiates behavior, - failure would change the situation.

Otherwise, assume competence within the monster's nature.


Static Values vs Rolls (Even More Aggressive)

Static values are preferred for monsters.

Roll only when: - the outcome is uncertain, - the monster is under pressure, - the PCs have forced adaptation.

Recommended uses: - Static attack values for routine attacks - Static defenses until tactics change - Static perception until deception or surprise matters

Monsters should not slow play.


Monster Behavior & Patterns

Monsters do not improvise like people.

They: - repeat behaviors, - follow instincts, - escalate in recognizable ways, - retreat or change state when thresholds are crossed.

Give monsters: - tells, - patterns, - rules they follow.

The fight becomes about learning, not grinding.


Morale and Monsters

Most monsters do not use Morale checks.

Instead, they use Behavior Thresholds.

Examples: - retreats when wounded - becomes enraged at half strength - flees when fire is introduced - changes tactics when prey escapes

If a monster has Morale, it should be explicit and rare.


Groups and Swarms (Creatures)

Creature swarms function differently from NPC swarms.

  • Swarms represent pressure, not coordination.
  • They gain durability, not intelligence.
  • They do not break morale; they thin.

Breaking a creature swarm usually requires: - area control, - fire, - environmental manipulation, - or removing the source.


Harm, Wounds, and Monster Anatomy

Monsters may: - ignore certain wound effects, - convert wounds into altered behavior, - lose abilities instead of taking penalties, - require specific harm types to be meaningfully injured.

A monster does not need to "die" to be defeated.

For monsters, defeat may mean: - driven off, - sealed, - pacified, - disrupted, - or rendered irrelevant.


Conditions and Monsters

Conditions should alter monster behavior, not mimic PC penalties.

Examples: - Shaken → changes attack pattern - Frightened → forces retreat - Immobilized → triggers desperation behavior

Avoid stacking Conditions purely for numerical effect.


Monsters and Recovery

Monsters do not recover like PCs.

  • Some regenerate rapidly.
  • Some never heal.
  • Some return changed.
  • Some do not recover at all.

Recovery should reinforce: - threat persistence, - environmental consequence, - narrative escalation.


GM Guidance

  • Monsters should not fight to the death unless their nature demands it.
  • Monsters should be more dangerous early than late.
  • Monsters should reward observation, not attrition.
  • Let clever avoidance be victory.
  • Let preparation matter more than damage.

Core Design Principle

NPCs enforce consequence.
Monsters enforce danger.

NPCs ask: "What will this cost you later?"
Monsters ask: "Can you survive this now?"

Both belong in Kaernest.
They are not interchangeable.
