5 Halloween One-Shot Ideas for D&D 5e, Ready to Run

Halloween is the one night a year your players want to be scared. They’ll lean in, they’ll whisper, and someone will absolutely insist on going into the cellar alone. All you need is a one-shot that fits in a single evening.

Here are five ready-to-steal hooks for fifth edition. Each one has a setup, a twist and a short list of monsters, all from the free System Reference Document, so you don’t need any extra books. After that come a few tips for making the night feel genuinely creepy.

1. The Last Lantern of Hollowmere

The hook: On the last night of harvest, every lantern in the marsh village of Hollowmere must burn until dawn. Tradition says the dead walk on any path left dark. This year, the lanterns are going out one by one.

What’s really going on: The lamplighter’s apprentice drowned in the marsh last spring. Their restless spirit is putting the lights out to lead the village to the spot where they died, so someone will finally find them. The real danger is everything else drawn to the dark.

Monsters: will-o’-wisps leading people off the paths, drowned zombies rising from the reeds, and a ghost who only wants to be found.

Best for: groups who like a mystery with a sad ending they can still put right.

2. The Patient Fields

The hook: A farmer begs for help. Every morning, the scarecrows in his fields stand a little closer to the house.

What’s really going on: A green hag made a deal with the village: a perfect harvest in exchange for “whatever walks the fields at the end of the season”. The villagers thought she meant the scarecrows. She didn’t. Some of them know exactly who signed, and they’d rather the party didn’t find out.

Monsters: the green hag, plus scarecrows built as reskinned animated armor (same stats, straw and sackcloth on the outside).

Best for: tables that love a bargain gone wrong and villagers with something to hide.

3. Dinner at the Wake

The hook: The party is invited to the wake of a wealthy merchant. Halfway through dinner, the merchant sits down at the head of the table. He’s very dead, very polite, and he wants to know which of his guests poisoned him.

What’s really going on: It’s a murder mystery where the victim is the host. The ghost can possess a guest to speak through them, which makes every conversation suspicious. Give each guest a motive, and let the party work out who did it before dawn.

Monsters: one ghost, and mostly a room full of liars. Expect very little combat.

Best for: roleplay-heavy groups, or a table that’s tired of initiative order.

4. The Bell That Rings Thirteen

The hook: At midnight, the old clock tower chimes thirteen times. In the morning, half the town has no shadow. By the next night, their shadows are hunting them.

What’s really going on: The thirteenth chime “unpins” shadows from their owners. Ring the bell thirteen times again before dawn and they snap back. The tower is full of things that would rather it stayed silent.

Monsters: shadows (which drain Strength, so your fighter will feel it), a specter in the bell chamber and a swarm of bats in the stairwell, because of course.

Best for: a fast, tense run against the clock.

5. The Masquerade of Borrowed Faces

The hook: The party gets invitations to a masked ball. Everyone must wear a mask, and nobody may reveal their face until the last dance.

What’s really going on: A doppelganger is replacing guests one by one, reading their thoughts so it can play the part perfectly. By the last dance, one of the people talking to the party isn’t who they claim to be. Maybe more than one.

Monsters: a doppelganger (or two, if you’re feeling mean) and a little animated armor guarding the host’s private rooms.

Best for: social sleuthing, paranoia, and players who love accusing each other.

How to make a Halloween one-shot feel creepy

Dread beats gore

Show the signs before you show the monster: a door left open, a lantern that wasn’t lit a minute ago, a villager who stops talking when the party walks in. What players imagine is always scarier than a stat block.

Keep it to three scenes and a finale

A one-shot has to end tonight. Plan three scenes, each with one clue that points to the next, then a finale. That fits comfortably in three to four hours, with time for snacks and arguing about the cellar.

Set the table

Dim the lights, use battery tealights rather than real flames near paper and dice bags, and put on a quiet ambient soundtrack (rain and creaking wood is plenty). Halloween grew out of Samhain, the Gaelic festival that marked the end of the harvest, when tradition held that the boundary with the otherworld grew thin. A pumpkin or two on the table does the rest. We happen to make a Samhain candle holder for exactly this kind of night.

Agree on the scary bits first

Horror works best when everyone has agreed how far it goes. Before you start, take two minutes for “lines and veils”: things you won’t include at all, and things that happen off-screen. Tools like the X-Card, created by John Stavropoulos, let anyone skip a moment without having to explain why. Nobody has to be brave about it.

End with a choice

The best Halloween endings ask the players to give something up: the hag’s harvest or the farmer’s son, the bell or the tower, the truth or a quiet funeral. A hard choice is what they’ll still be talking about next year.

Pre-gens in five minutes, not fifty

The one thing that can sink a one-shot is spending the first hour on character creation. Hand out pre-generated characters, or ask players to bring them.

That’s where our Nightbloom class sheets come in. Type in the level and ability scores, and the sheet works out modifiers, saves, skills, spell save DC and spell slots for you, for the 2014 or 2024 rules. Decide at the last minute that the party should be level 5 instead of 3? Change the number and everything updates. You can try the live sheet in your browser before you print anything.

Happy haunting. And if someone does go into the cellar alone, you have our permission to roll in front of the screen.
