The Replacement is a crime noir one-shot for 5e — a complete, ready-to-run session for small groups where your players are not the heroes, and the last crew who took this job is already on the floor. Every Game Master knows the bind: you want a night with real teeth and choices your table will still be arguing about next week, but you do not have a weekend to build one. This adventure hands you that night, prepped and playable. Your players arrive at a dockside warehouse on emergency notice, find three bodies, and meet their new employer — a beholder crime boss named Vorrath who assumes they were fully briefed. They were not. Over four acts they must fake competence, work out what the job actually is, and decide what to do when they discover a weapon that can strip a beholder of everything that makes him a beholder. Open the book and run it tonight.
A Job You Are Not Allowed to Ask Questions About
Most 5e one-shots open by telling your players what they are doing. This one opens by telling them not to ask. Vorrath does not brief them. Harven, his senior lieutenant, does not explain. The entire first half of the session is a party of professionals performing competence while frantically trying to work out what they were hired for — and that discomfort is the experience, not a bug in it. It turns an ordinary evening into the kind of session where nobody checks their phone.
The Suspicion Meter
A single visible track from one to five sits on the table where everyone can see it, and it measures exactly one thing: how much Vorrath distrusts the party. It climbs when they fumble a question, refuse an order, or leave tracks. It never drops below one. By the final act it dictates how many loyalists are standing in the room when the players walk in — which means the difficulty of the ending is something they authored themselves, one choice at a time. The threat is never behind the screen. It is on the table, in front of them, going up.
The Impression Stone
At the end of every act, each player presses a warm black stone to their forehead and holds it for three seconds while Vorrath reads their surface thoughts. It is not optional. It is not pleasant. And it demands a Performance check — not to lie, because at first they have nothing to hide, but to present as people who know exactly what they are doing. Fail, and the meter climbs. By Act Three, when they are carrying a secret that would get them killed, that same check becomes the most frightening roll of the night.
A Villain Who Never Raises His Voice
Vorrath is not a boss fight with a health bar attached. He is a criminal empire in one body, and he is written to be played completely flat — no monologues, no theatrics, no threats made twice. He kills the way other people sigh. When someone dies in front of the party in Act One, it is punctuation, and then the scene simply moves on. The silence afterward is the threat. Played correctly, every moment your players spend in his presence feels like standing too close to something that could end them as an afterthought.
The Weapon That Changes Everything
The Oculus Staff is four feet of cold iron and old runes, built centuries ago by a mage guild during a beholder incursion. One charge, a fifteen-foot cone, no saving throw — and the most dangerous creature in the district drops to a bite attack and a twenty-foot fly speed for five minutes. It is in the players’ hands by the end of Act Three. What they do with it is the entire adventure, and the five-minute clock is one of the tightest, most electric windows we have ever put on a table.
The Conspiracy Underneath
The previous crew did not die on the job. They were killed by Harven, who has served Vorrath for eleven years, watched him execute subordinates over tone of voice, and decided he is finished waiting. He is standing beside his employer in the final act, calm and professional, waiting to find out whether the replacements found what he buried. Every clue the party turns up tightens that room a little further.
Four Exits, No Right Answer
The final act is a room, not a corridor. Your players walk into Vorrath’s office holding a weapon, a secret, and a suspicion meter that has been quietly deciding their odds all night, and then they choose.
- Deliver and walk away. Take the money. Say nothing. Safest, hollowest, and Harven is still standing there when the door closes.
- Give Harven up. Vorrath listens, then tells the players to do it themselves — to prove they are worth keeping.
- Blackmail Harven. Get paid by both sides, walk out with gold in each pocket and two threads behind you that could unravel any day.
- Take the shot. Fire the staff, start the clock, and try to end a beholder in five minutes with whatever you brought with you.
None of these is the correct one, and the book is explicit that the Game Master must not steer. Whatever the table commits to, the session ends there — no epilogue, no softening. Let it land.
What Is Included in This 5e Crime Noir One-Shot
This is a complete session between two covers, written for busy Game Masters who want depth without the prep grind. Everything you need is here — no supplements, no homebrew patching, no missing pieces.
- A complete two-to-three hour adventure for two to three players at levels two to three, with zero prep
- Four acts of escalating pressure, with hardboiled read-aloud narration throughout

- A full beholder stat block with behaviour notes, plus a suppressed profile for the five-minute window
- Full fifth-edition stat blocks for every creature and NPC, including Darro and his crew
- Four ready-made characters — Mira Holt, Gareth Cull, Sable, and Dorin Ashfall — any two of which form a viable party
- Battle maps for the port district, the warehouse, the alley, the bar, and Vorrath’s office
- Opening hooks, campaign seeds, and a “What If?” appendix for when players go somewhere you did not expect
- A quick-reference sheet for the Suspicion Meter and stone contacts, and a full breakdown of Vorrath’s empire
- Four distinct endings the players choose entirely for themselves
Perfect For
This one was built for a specific kind of table, and it knows exactly who it is for.
- Busy Game Masters who want a tense, atmospheric session with no prep grind.
- Small groups and two-player duos who want pressure and consequence rather than a long dungeon.
- Tables who like playing the wrong people — fixers, professionals, and characters with no illusions about the work.
- Game Masters who want a beholder at the table without needing a high-level party to justify it.
- Anyone with a free evening looking for a single-session detour to drop into an ongoing fifth-edition campaign.
A Note on Tone
This is a mature adventure and it does not pretend otherwise. It contains criminal violence, coercion and extortion as working player tools, an optional torture scene with real mechanical consequences, a recurring involuntary psychic intrusion, and moral ambiguity that is never resolved. Nobody in this story is innocent — not the gang, not the contacts, not the previous crew, and certainly not the players. Review the content warnings with your group before you sit down, and if that is what your table wants, few adventures deliver it this cleanly.
Part of the Ready Adventure Series
The Replacement joins the Ready Adventure Series, a growing library of small-group 5e one-shots built for two to three players and a single evening of play. Every title is designed the same way: zero prep, a complete session in a couple of hours, meaningful choices, and no railroading. If your table loves a night that feels finished — a real beginning, middle, and end without a month of planning — this is the shelf to watch.
If the criminal underworld is what pulls you in, the series has neighbours worth a look. The Score is a heist where the players build the plan before a single die is rolled and then live with every decision they made, and The Merchant’s Vault is an urban break-in where the employer has been lying from the start. Like The Replacement, each is a self-contained session you can drop into any campaign — same design promise, a completely different night at the table.
Take the Job
You do not need another dungeon. You need a night where the stakes are personal, the employer is worse than the monster, and the people at the table have to decide who they are willing to be. The Replacement gives you all of it in one ready-to-run package, with the math already checked and the pressure already built in. Take the job. Find the weapon. Decide who survives.
Four exits, one beholder, and five minutes on the clock — The Replacement turns a single evening into a crime noir one-shot your players will still be arguing about long after the gold is spent.
