[DH] DH Mechanics Conversion Test, Part 2, Scene 2
Absolutely. I think this is a very good scene to trial because The Phantom Transit System is exactly the kind of encounter that can show whether the Motherboard conversion actually feels like Daggerheart rather than D&D with the serial numbers filed off.
I’ll run it as a miniature GM session, using:
Motherboard - The Night Land_final2.docx as the primary adventure authority.
DDAL-EB-01 - The Night Land only where the Motherboard draft explicitly preserves the original structure.
The finalized four PC sheets for SHINJO, ELORIN, YOSEF, and THERIS.
Daggerheart SRD May 20, 2025 for the actual resolution mechanics.
The PCs will make decisions according to their established personalities and roles, rather than me treating them as four interchangeable tactical robots.
The Motherboard draft explicitly says this scene should be an objective encounter, not a combat encounter: reach the stranded operative, understand the transit hazard, get them out, and avoid being caught by the system.
The source adventure gives us the underlying skeleton: the transit threat approaches on a timed route, originally reaching the stranded scout at the end of round five, while the characters must reach and move the stranded person.
So let's actually play it.
PART 2, SCENE 2
THE PHANTOM TRANSIT SYSTEM
GM Setup
Location: The Wastes, an abandoned Ancient transit route.
Objective: Rescue the stranded salvage operative.
Countdown: 5 rounds.
Transit system: An enormous Ancient transport platform still running its original route. It does not behave like a ghost or supernatural entity. It is simply a machine continuing its programmed operation centuries after civilization stopped using it.
The transit line crosses the ruins ahead.
The system is approaching.
And someone is trapped on it.
Before the first roll
The four-person crew has already spent several hours moving through the Wastes.
The landscape is exactly what Motherboard wants it to be: dead infrastructure, exposed machinery, abandoned routes and old systems that nobody alive fully understands.
Then Shinjo stops.
Not dramatically.
Just stops walking.
Theris notices first.
THERIS:
"What's wrong?"
Shinjo looks toward the ruins.
SHINJO:
"Something's moving."
Elorin looks at the empty transit line.
ELORIN:
"Where?"
Shinjo doesn't answer immediately.
He is listening.
Yosef watches him instead of the ruins.
That's important.
Yosef knows Shinjo's version of "something's wrong" isn't necessarily the same thing as everyone else's.
Then, somewhere beyond the collapsed structures:
THOOM.
A vibration runs through the ground.
Dust falls from a broken transit support.
Another sound.
THOOM.
Closer.
The four look toward the old route.
Something enormous is coming.
ROUND 1
GM
Ahead, the old transit route emerges from between two collapsed industrial structures.
A battered Ancient transport system is moving along it.
It is not glowing.
It is not transparent.
It is not a ghost.
It is a gigantic, half-functional machine, its outer shell scarred with decades of corrosion and impact damage. Ancient power systems flare underneath it as it follows the old route with absolute indifference.
And then you see something else.
Approximately 200 feet ahead, a person is trapped beside the transit line.
They are alive.
Their equipment is scattered around them.
They are trying to get up.
The machine is coming straight toward them.
GM
"Someone is down there."
SHINJO
Shinjo immediately tries to determine whether the machine is actually following the visible route or whether its movement is being affected by something else.
This is very much his territory.
GM:
"Give me an Instinct roll to read the machine's behavior."
Shinjo's Instinct is +1.
🎲 SHINJO: Instinct +1 vs Difficulty 12
Hope: 2
Fear: 8
Total: 11
❌ FAILURE WITH FEAR
The total misses the Difficulty, and Fear is higher.
Per Daggerheart, that means failure with a major consequence and the GM gains Fear.
GM gains 1 Fear.
GM Move
Shinjo realizes the machine isn't simply traveling along the rail.
It is correcting its own trajectory.
The route isn't just a guide.
It's an active navigation system.
The transit machine abruptly shifts several feet sideways as it compensates for debris on the line.
The movement kicks a slab of Ancient material across the route.
It slams into the ground.
KRAK.
The stranded operative looks toward the noise.
They see the crew.
They start waving.
OPERATIVE:
"HELP!"
The machine is still coming.
And now the crew knows something important:
The transit system is actively compensating for obstacles.
Which means trying to block it may be considerably worse than trying to work around it.
YOSEF
Yosef immediately studies the machine.
Not the machine itself.
Its behavior.
Speed.
Correction.
Route.
Momentum.
Distance.
The operative's position.
The broken infrastructure around them.
This is exactly the kind of thing his tactical intelligence role exists for. His sheet explicitly defines his role as battlefield intelligence and squad coordination rather than engineering.
YOSEF:
"Don't block it."
Theris looks at him.
"Why?"
"Because it will compensate."
A beat.
"Then what?"
Yosef looks at the transit line.
"Move her."
🎲 YOSEF: Knowledge +2 vs Difficulty 13
Yosef uses Threat Intelligence & Systems Analysis +2.
Hope: 5
Fear: 8
Total: 15
✅ SUCCESS WITH FEAR
The action succeeds, but the Fear die is higher.
GM gains 1 Fear.
Yosef successfully understands the system.
It is running a fixed operational loop.
It will not stop.
It will not meaningfully slow.
It will not recognize the stranded operative as an obstacle.
It will simply continue.
But Yosef also identifies something useful.
There is a maintenance access point approximately 40 feet from the operative.
If someone can reach that point, they may be able to get the operative away from the main route without having to physically drag them across the entire distance.
The cost?
Yosef's analysis reveals that the maintenance access point is partially energized.
Touching the wrong section could cause a serious electrical discharge.
YOSEF:
"Elorin."
Elorin looks over.
"Maintenance access. Forty feet from her."
A pause.
"Live system."
Elorin smiles faintly.
"That's better."
Theris gives him a look.
"That wasn't permission."
ELORIN
Elorin moves toward the nearest access junction.
This is precisely his specialty. His sheet gives him Knowledge +2, along with Ancient Technology Scholar and Scrap Engineer.
He doesn't attempt to shut the machine down.
That would be absurd.
Instead, he wants to identify which part of the system can be safely manipulated.
GM
"Knowledge or Finesse?"
Elorin thinks.
"Knowledge."
Good call.
He's trying to understand the system before touching it.
🎲 ELORIN: Knowledge +2 vs Difficulty 13
Hope: 9
Fear: 5
Total: 16
But...
He chooses to spend 1 Hope on Scrap Engineer +2.
Total becomes:
18
✅ SUCCESS WITH HOPE
Per Daggerheart, success with Hope means success and gaining a Hope.
Elorin gains 1 Hope.
GM
Elorin opens the battered access housing.
Inside is a mess of Ancient components.
Not random.
Not damaged beyond recognition.
Just old.
Very old.
He sees the logic.
ELORIN:
"Oh."
Theris:
"What?"
Elorin points.
"The system isn't powering the transit vehicle continuously."
Yosef looks over.
"Then what?"
"It pulses."
Shinjo has gone very still.
Elorin continues.
"Every time the vehicle crosses one of these junctions, it dumps excess charge into the route."
Theris:
"And?"
Elorin:
"And this access point is about to do that."
He looks toward the operative.
"Which means we have about one chance to use it."
ROUND 2
The transit system is now 160 feet away.
The operative is still stranded.
The machine is getting closer.
Theris takes command.
Not because the adventure says she should.
Because this is exactly what Theris does.
She looks at everyone.
THERIS:
"Shinjo. Find the safe route."
"Elorin. Keep that junction alive."
"Yosef."
Yosef looks at her.
"Tell me where you want me."
Yosef considers the battlefield.
Then:
"With her."
Theris nods.
"Go."
SHINJO
Shinjo studies the ruins.
He isn't trying to understand the machine anymore.
He's looking for the path that shouldn't be obvious.
That is his particular talent.
His character sheet specifically establishes his ability to sense hidden technology and machine activity.
🎲 SHINJO: Instinct +1 vs Difficulty 12
Hope: 12
Fear: 6
Total: 19
✅ SUCCESS WITH HOPE
Shinjo gains 1 Hope.
He sees it.
A maintenance bridge.
Half-collapsed.
It crosses the route approximately thirty feet from the stranded operative.
It looks unusable.
But Shinjo knows immediately that it isn't.
He points.
SHINJO:
"There."
Elorin follows his finger.
"I don't see a bridge."
Shinjo:
"That's because it's underneath the debris."
Theris:
"Can we cross it?"
Shinjo:
"Yes."
Yosef:
"Probability?"
Shinjo looks at him.
"Enough."
Yosef pauses.
That is not a number.
He doesn't like that.
Theris does.
"Good enough."
THERIS
Theris moves.
She has Agility +1, but the obvious challenge is simply reaching the operative through unstable terrain. Her sheet establishes her as the physical anchor of the crew.
🎲 THERIS: Agility +1 vs Difficulty 10
Hope: 5
Fear: 11
Total: 17
✅ SUCCESS WITH FEAR
Theris succeeds.
GM gains another Fear.
She crosses the debris field.
But the cost is immediate.
A section of broken flooring collapses under her.
Theris catches herself against a steel support.
THERIS:
"Fine."
Yosef:
"You almost fell."
"I'm aware."
She keeps moving.
The operative is now only thirty feet away.
ROUND 3
The transit system is now 120 feet away.
The machine's approach changes the environment.
Air pressure builds.
Loose scrap starts sliding toward the route.
The operative is struggling to move.
Theris reaches her.
OPERATIVE:
"Don't touch the line!"
Theris:
"Wasn't planning to."
She looks at the woman.
"Can you walk?"
"Leg's trapped."
Theris looks down.
The operative's leg is pinned beneath a section of Ancient structural material.
Theris grabs it.
This is where the original adventure required the rescuers to physically move the petrified scout, but the Motherboard conversion explicitly broadens the scene into creative Agility, Instinct, Knowledge, teamwork, and equipment use.
Theris doesn't have to solve this with a single brute-force check.
And she doesn't.
She calls:
"Elorin!"
ELORIN
Elorin reaches the maintenance junction.
He has one chance to use the energy pulse.
He wants to redirect the pulse into the actuator locking the debris in place.
🎲 ELORIN: Knowledge +2 vs Difficulty 13
He has already used his Experience this scene.
So this is just:
Knowledge +2
Hope: 5
Fear: 7
Total: 14
✅ SUCCESS WITH FEAR
The system responds.
Elorin twists two contacts.
The junction screams.
ZZZZK.
The locking mechanism releases.
The debris shifts.
Theris immediately pulls.
The operative's leg comes free.
But the electrical discharge arcs across Elorin's glove.
He marks 1 Stress.
GM Move: the junction is now unstable.
It won't be usable again.
Elorin looks at the smoking access panel.
"That was the only one."
Theris:
"Then we'd better not need it twice."
YOSEF
Yosef watches the transit system.
It is now 80 feet away.
He sees the route.
The maintenance bridge.
The debris.
Theris.
The operative.
Elorin.
He calculates.
Then he says:
"Theris."
She looks up.
"When I say move, don't run toward the bridge."
She frowns.
"Why?"
"Because the machine's pressure wave reaches the bridge first."
She looks at him.
"Where?"
"Left."
"How far?"
"Twenty feet."
Theris nods.
That's enough.
Yosef isn't telling her what to do.
He's giving her the information she needs to decide.
ROUND 4
The machine is 40 feet away.
The ground shakes.
The operative looks terrified.
Theris gets an arm around her.
"Can you move?"
"Yes."
"Then move."
They run.
🎲 THERIS: Agility +1 vs Difficulty 10
Hope: 3
Fear: 12
Total: 16
✅ SUCCESS WITH FEAR
Theris gets the operative moving.
But the machine's pressure wave hits.
Both are thrown sideways.
Theris takes 1 Stress.
The operative crashes against the ruined bridge.
Shinjo is already there.
SHINJO
Shinjo doesn't try to catch them physically.
He activates his Network Drift.
His Faerie Wings allow him to reposition through the air, and the character sheet explicitly reskins this as temporarily disconnecting from physical constraints.
He gets airborne.
Then drops beside the operative.
SHINJO:
"Up."
The operative grabs his arm.
Shinjo lifts.
They clear the worst of the pressure wave.
ROUND 5
The transit machine is almost here.
20 feet.
There is no more time.
Theris, Shinjo and the operative are on the far side of the route.
Elorin is still near the maintenance junction.
Yosef is watching the machine.
Then Yosef sees something.
The machine's route correction.
It isn't centered.
It is drifting.
Straight toward Elorin.
YOSEF:
"ELORIN."
Elorin looks up.
The machine is coming.
Yosef has a split second.
He can shout.
Or he can use his tactical intervention.
Witch's Charm
Yosef's character sheet specifically establishes Real-Time Corrective Guidance Protocol: when an ally fails an action roll, Yosef can spend 3 Hope to convert it into a success with Fear.
But Elorin hasn't rolled yet.
So Yosef can't use it.
Instead:
YOSEF:
"LEFT."
Elorin doesn't ask why.
He moves.
ELORIN
Elorin sprints away from the junction.
🎲 ELORIN: Agility -1 vs Difficulty 10
Hope: 10
Fear: 4
Total: 13
✅ SUCCESS WITH HOPE
Elorin gains 1 Hope.
He clears the route.
The Ancient transit system tears through the abandoned station.
There is no explosion.
No ghost.
No supernatural scream.
Just an enormous machine doing exactly what it was built to do.
It passes.
THOOOOOM.
Air and dust blast across the ruins.
Then silence.
SCENE RESOLUTION
For several seconds nobody speaks.
The operative is lying on the ground.
Theris checks her.
"Broken?"
The operative flexes her leg.
"No."
Theris nods.
"Good."
Elorin walks back toward the smoking maintenance junction.
Shinjo is looking at the transit line.
Yosef is looking at Shinjo.
The operative finally speaks.
"I thought it was going to stop."
Elorin looks at her.
"It wasn't malfunctioning."
She stares.
"What?"
"It was working."
That lands differently.
The machine wasn't haunting the route.
It wasn't attacking anyone.
It wasn't malfunctioning in the way they assumed.
It was simply still performing its original job.
Century after century.
Run the route.
Clear the line.
Continue.
The Operative's Information
Once she's recovered, the operative explains why she was there.
She had been looking for recoverable components along the old transit route.
She found:
several intact Ancient junction components;
evidence that portions of the transit network are still powered;
damaged equipment from previous scavengers;
strange movement around the ruins;
and the distinct impression that something had been observing her.
Importantly, she knows nothing about the Reliquary.
That's intentional in the Motherboard draft. The rescued operative provides local information rather than conspiracy exposition.
🎲 Final Party State
| Character | HP | Stress | Hope | Important outcome |
|---|---|---|---|---|
| SHINJO | 5/5 | 0/6 | 4/6 | Located the safe route and extracted the operative |
| ELORIN | 5/5 | 1/7 | 4/6 | Diagnosed and manipulated the transit system |
| YOSEF | 6/6 | 0/7 | 2/6 | Correctly modeled the transit behavior and coordinated the rescue |
| THERIS | 7/7 | 2/6 | 2/6 | Physically reached and extracted the operative |
GM Fear generated: 5
The exact Daggerheart texture here is important. The rolls weren't simply pass/fail gates. Success with Fear let the crew accomplish things while giving the GM escalating resources for complications, while Success with Hope rewarded successful action with Hope.
What I Think This Trial Reveals
1. The scene works much better as an objective than a combat
This is probably the biggest success.
Nobody needed to attack anything.
The tension came from:
distance → time → machine behavior → positioning → teamwork.
That's exactly what the Motherboard draft says this scene should be doing.
The original D&D encounter has a much more explicit "initiative, reach Garundah, make Athletics check, don't get hit by train" structure.
Daggerheart lets us turn that into a sequence of fictional decisions, with rolls occurring when the outcome is uncertain.
2. The four PCs actually feel different
This is the strongest part of the test.
Theris didn't become "the Strength character."
She became the person who physically commits to the rescue once the plan exists.
Elorin didn't become "the wizard."
He became the person who looks at Ancient machinery and says:
"Give me ten minutes."
His character sheet explicitly positions him as the technological specialist, artificer, ranged utility character and healer.
Shinjo didn't become a generic scout.
His weird relationship with technology actually mattered.
He didn't understand the system academically.
He felt where the safe route was.
That distinction is very important to his character.
And Yosef worked exactly as intended.
He wasn't an engineer.
He wasn't the leader.
He wasn't secretly the protagonist.
He looked at a moving system and turned it into actionable information.
That fits the established distinction that Yosef's battlefield-intelligence role is something he does, rather than his entire personality being "tactical analyst guy."
3. Yosef's Zero-Interference Protocol actually works beautifully here
This scene is an especially good test for that concept.
Yosef never needs to physically manipulate the transit system.
His "attack-like" or analytical mechanics can remain entirely fictionalized as information.
In this scene he effectively says:
"Don't block it."
"Move her."
"Left."
That's Yosef.
His contribution is not doing the thing.
His contribution is making sure the people who do the thing are doing the right thing at the right time.
That makes his role mechanically useful without turning him into another artificer.
4. The original "five rounds" structure should probably stay
I like this.
It gives the scene a heartbeat.
The original adventure establishes the transit threat at 200 feet, moving 40 feet each round and reaching the target at the end of round five.
I would preserve that in the Motherboard version, but not necessarily preserve the original requirement that the solution must be a Strength check.
The Motherboard draft specifically says the scene should encourage Agility, Instinct, Knowledge, teamwork and creative equipment use.
This trial demonstrates why.
One Thing I Would Change After This Trial
I'd actually make the transit countdown visible to the players.
Not necessarily:
"ROUND 3 OF 5"
But something like:
Transit Status
200 ft → 160 ft → 120 ft → 80 ft → 40 ft → 0
That gives the players something tangible to react to.
Daggerheart loves this sort of pressure because every roll can change the fiction without needing a giant combat spreadsheet.
And importantly, Failure with Fear becomes frightening without simply meaning "take damage." The SRD explicitly encourages GM consequences such as marking Stress, introducing threats, or raising the stakes.
That is exactly what happened here.
Verdict
The Phantom Transit System passes the trial.
More importantly, it passes for the right reason.
It doesn't feel like:
D&D encounter converted into Daggerheart numbers.
It feels like:
A Daggerheart objective encounter happening in the Motherboard world.
And the four-character division is particularly clean:
Shinjo finds the path.
Yosef understands the problem.
Elorin manipulates the technology.
Theris gets the person home.
That is essentially the crew architecture you established in the character documents: Theris brings the salvage home, Elorin understands it, Shinjo finds it, and Yosef makes sure everyone survives finding it.
The next really interesting test would be to run Scene 3, the Stranded Operative, immediately afterward without skipping the roleplay, because that's where we can see whether the adventure transitions naturally from objective → investigation → information → Node-Stalker encounter rather than feeling like four disconnected encounter boxes.
