PREDATORY ENCOUNTERS - IMPROVING THE ENCOUNTER DIE WITH
TENSION, STEALTH & DUNGEON REACTIVITY, OR - A SIMPLE UNDERCLOCK ALTERNATIVE
Do you want encounters to occur more
regularly?
Do you want the dungeon to respond to your players'
foolishness?
Do you want your players to feel hunted and pursued?
Try the Predatory Encounter Die!*

Standard Encounter Rolls
At its most basic level, the typical encounter roll looks
like this:
"Every 10 minutes, roll 1d6. On a 1, a random
encounter occurs."
Overloaded Encounter Rolls
A sagely fellow (
Necropraxis
I believe) once asked “what about the other numbers?”. Overloaded Encounter
rolls largely function the same as Standard Encounter rolls, save that there
are results for rolls of 2-6. Meaning that rolling is always meaningful. These
results typically include things such as light source depletion, a description
of the environment or signs/spoors/omens/clues that hint at nearby wandering
monsters. Everyone has their own formula for a good Overloaded Encounter die.
Until I share mine, find some
here,
here
and
here
(but there are many more). BUT, some still felt this roll was lacking - ‘is
1-in-6 frequent enough?’ or ‘this is fun, but still feels static’. I know I
have certainly run dungeon sessions and one-shots where due to the whims of the
dice, there have been no actual encounters. Many have tried to fix this, which
leads us to…
The Underclock
Somewhat recently, Arnold K of Goblin Punch tackled this
problem by introducing
The
Underclock which is essentially a countdown to a guaranteed encounter.
The Underclock does a few things, it is meant to ensure an encounter, suggest
that the dungeon is responding to the actions of the players and create a sense
of tension, a feeling of pursuit. However, in practice, (I have played in games
with the Underclock) it introduces too much predictability - players feel
safe when the Underclock is high, plus it's just that bit fiddlier than rolling
a die. But what if there was…
Another Way - The PREDATORY ENCOUNTER DIE
What if we could combine the variated, meaningful results of
the Overloaded Encounter Die, the tension of The Underclock and ensure
encounter frequency in a simple manner? That's this method. The standard
encounter roll becomes a measure of the dungeon’s awareness as it shifts and
searches for the players. It's very simple, surely done before, but, this is
it:

How It Works
1. Start with a d6 (this is your Encounter Die) as
standard.
2. Roll it whenever you would normally check for encounters,
every ten minutes, every three rooms, etc.
3. If the result is 6 (or higher), an
encounter occurs.
4. Results of 2-5 trigger standard Overloaded Encounter
effects (light depletion, environmental signs, etc.) according to your taste.
In addition to any effect on rolls 2-5, the encounter die increases in size
(d8 → d10 → d12 → d20) as the dungeon hones in on the party. When you next roll
for encounters, do so with the new die size. Encounters continue to occur on a 6
or higher. The probability grows - the monsters are getting nearer!
5. A result of 1, lowers the Predatory Encounter Die size by
one increment.
6. Importantly, the Predatory Encounter die also increases
in size whenever player characters make loud noises, allow
intelligent/organised enemies to escape or otherwise draw attention to
themselves.
7. Once an encounter does occur and is resolved (or the
party leave the dungeon), the encounter die resets back to d6. However,
the minimum encounter die size can increase if the dungeon becomes particularly
alert.
8. Hiding successfully for 10 minutes (which still requires
an encounter roll as time passes) can reduce the encounter die back to a
d6.
Encounter Probability by Die Size
Die Size_____Encounter
Chance
d6__________16.67%
d8__________37.5%
d10_________50%
d12_________58.33%
(weird!)
d20_________75%
It works! The probability is weird and lumpy but your
players will get it, big = bad. This method is meant to be
player-facing. Let your players see the die grow, make them roll it. Having it
out on the table will give rise to tension and be a constant reminder that
something is looking for them and that it is getting closer. However, if the encounter rate seems too high, check out the alternate method below.

Tips, Adjustments and Options
- A
roll of 1 on the encounter die can represent a lull or lapse in alertness
and lowers the die size by one.
- What
constitutes a rise in the encounter die? You know already, explosions, throwing skeletons down
wells, kicking down doors, any kind of demolition/destruction, if
intelligent enemies are able and allowed to report the party’s location,
and depending on your setting and opinion - the use of firearms. Anything
that feels like it should increase the dungeon’s alertness levels -
should.
- If
needed, use a small tracker to help keep on top of the encounter die, all
that would be needed is 5 boxes, labelled d6 through to d20 and a bead to
place on the current encounter die size. Let the players see this.
- When
hiding, players should think about how and where they are hiding and
describe it as they would any other action, such as with inspecting and
disarming traps for instance. If your system has a stealth skill, that can
be used only if an encounter is rolled while the party is hidden. On a
successful stealth roll, reroll the encounter die or bypass the encounter
- it's up to you. Their description and hiding place may give them a bonus
or malus to the roll. It might be so good they don’t even need to roll!
This will increase that particular feeling of stealth in your games and
allow for scenes I’d never or very rarely seen before - the DM describing
the party hiding while a monster walks past them. I can see the various
rolls, results and DM description in this classic LotR scene.
- This
is optional; If players severely disrupt the dungeon, increase the minimum
die size (e.g. it defaults to a d8 instead of d6). Perhaps if the party
steals the all-important Blue Jewel or the Dragon’s egg, slay the
High-Priest, get sprayed with stinking monster-bait, stab the dungeon’s
beating heart, insult the Goblin Queen. Any dramatic event might qualify
and reducing the minimum die size would be bespoke to whatever caused its
rise.
- Generous
DMs can offer a reprieve by temporarily using a d4 encounter die that
cannot trigger encounters.
- Predatory
Encounters are tougher than regular encounter mechanics, this is ok. It
will make your players tougher in kind.
The Alternate Method
- However, to reduce the encounter rate, consider this - remove the out of turn and automatic increases to the encounter die. Instead, during a 10 minute turn, ask yourself as the DM, 'do the player's actions warrant an increase in the size of encounter die?' if yes, increase the die size, if not keep the encounter die size and roll as normal. There are no automatic increases with this method, instead you would immediately roll for encounters with the current die size whenever the party do anything that might draw attention to themselves. Otherwise, the mechanic remains the same.
Why Use this Rule?
This slight change for rolling for encounters retains
meaning with every roll, creates tension, meaningful choices and gives the
dungeon another avenue to feel like a living thing.
- It maintains traditional encounter mechanics while adding
a rising feeling of escalation and responsiveness.
- The dungeon feels more alive, it can react more
dynamically to the players' actions and will feel less empty.
- The dungeon responds organically, the more players create
a ruckus, the more alert its inhabitants become in trying to find them.
- The encounter die, always increases in size. Players will
feel hunted, pursued, like the intruders they are. Even after an encounter,
there is no assumed safety or reprieve unless earned.
- Encounters remain unpredictable. Players never know
exactly when the next encounter will happen, but they know how much more
likely it will be. HP low, Encounter Die big 😱,
let's roll…. a 3! Phew!
- Stealth and caution become meaningful, not assumed. As
stated, players can attempt to lower the encounter die size by hiding, taking
special precautions or otherwise satiating the dungeon. I understand
adventurers are assumed to be moving quietly at all times but this change
brings that behaviour to the fore. Player’s will devote time to hiding (which
they would never otherwise do) and search out places to hide. Using Predatory
Encounter rolls is like a stealth system in of itself, the higher the encounter
die size the harder it is to hide.
Try it out in your next session, see how the game
changes.
Let me know how it works for you, what you tweaked or
changed and if you like this post, do follow. I’ve got a small post about
making light a mechanically important resource coming very soon. It has some elegance to it if I do say so myself.
