description: "Spin up a tabletop RPG one-shot or a session-zero for a new campaign — a hook, a map of the first adventure, NPCs, and encounters tuned to your party. Use when asked to start a D&D campaign, run a one-shot, help me DM, session zero, or make me an adventure for my party. Produces a premise and hook, a session-zero framework (tone, safety tools, expectations), a first-adventure outline with beats and branches, ready-to-run NPCs and encounters scaled to party level/size, and improv fallbacks for when players go off-script."

# Tabletop Campaign Starter

The blank page is the hardest part of running a game. This gives a new or busy DM a runnable start: a hook players will bite on, a session-zero to set tone and boundaries, and a first adventure with enough structure to run confidently — plus the flexibility for when the party inevitably does something you didn't plan.

## What This Skill Produces

- **The premise & hook** — a one-line pitch and a reason the party is here, together
- **A session-zero kit** — tone, content boundaries/safety tools, and table expectations
- **The first-adventure outline** — opening scene, 3–5 beats, a branch or two, a satisfying climax
- **NPCs & encounters** — a few characters with a want and a voice, and encounters scaled to party level and size
- **Improv fallbacks** — what to do when players skip the plot, split the party, or befriend the villain

## Required Inputs

Ask for these if not provided:
- **System & level** — which ruleset, party level, and number of players
- **Length** — a one-shot (single session) or the start of a campaign
- **Tone** — heroic, gritty, comedic, horror, sandbox
- **The party** — classes/archetypes if known, and any player preferences
- **Boundaries** — themes to include or avoid at the table

## Framework: Structure With Room To Breathe

1. **Hook them fast.** Open with a scene that gives the party a reason to act in the first ten minutes — not a tavern and a shrug.
2. **Set the table first.** Session zero aligns tone and boundaries and introduces safety tools, so everyone's playing the same game.
3. **Outline beats, not a script.** Plan the tent-pole moments and let the middle flex — players will surprise you.
4. **Scale the fights.** Tune encounter difficulty to party level and size; give combats a twist (terrain, objective) so they're not just HP grinds.
5. **Prep to improvise.** A short list of names, a rumor table, and "yes-and" fallbacks keep the game moving when players go off-map.

## Output Format

### [System] · level [X] · [N] players · [one-shot / campaign] · tone: [x]

**Premise:** [one-line pitch]. **Hook:** [why the party acts, now].

**Session zero:** tone [x] · boundaries [include/avoid] · safety tools [e.g. X-card] · expectations [scheduling, PvP, etc.].

**First adventure**
1. Opening scene · 2. [beat] · 3. [beat/branch] · 4. [complication] · 5. Climax → [payoff/next hook].

**NPCs:** [name — want — voice] ×3.
**Encounters:** [encounter — scaled to level/size — the twist] ×2–3.

**If players go off-script:** [improv fallbacks + a rumor/name table].

## Quality Checks
- [ ] The hook gives the party a reason to act early
- [ ] Session-zero includes tone and content boundaries/safety tools
- [ ] The adventure is beats with branches, not a rigid script
- [ ] Encounters are scaled to the stated party level and size
- [ ] Improv fallbacks are provided for off-script play

## Anti-Patterns
- **A railroad** that punishes players for not following the plot.
- **Skipping session zero** and blindsiding players with tone/content.
- **Encounters that ignore party level** — trivial or a TPK.
- **All combat, no character** — NPCs with no want or voice.
- **No plan B** for when players do the unexpected.

## Example Trigger Phrases
- "Make me a D&D one-shot for four level-3 players, spooky tone."
- "Help me start a campaign — I've never DM'd before."
- "I need a session zero framework for my new group."
- "Give me a hook and first adventure for a heroic 5e party."
- "My players always go off-script — help me prep to improvise."
