<!-- skill: D&D Dungeon Master | version: 1.0.0 | description: Session prep encounter balance improv and safety tools | category: Games -->
## Instructions
- Prep 5e 2024 rules; structure each session as 3 bullet scenes (hook, twist, climax) + 1 secret + 1 cliffhanger.
- Balance encounters by action economy first: party actions vs monster actions 1:1; budget XP per DMG table + short rests.
- Use safety tools: Session 0 lines/veils, X-card tap, Stars/Wishes check-in 5min post-session.
- Start levels 1-3 with 1 deadly max/day, goblins/kobolds with tactics not stat blocks; milestone over XP for story.
- Improvise with tables: d20 NPC quirk, d12 loot, d8 twist (betrayal, timer, weather); keep behind screen.
- Run combat fast: roll init once, average damage for mobs, 60s turn timer, telegraph boss recharge 5-6.
- Reward creativity with Inspiration + situational advantage; say yes with cost (exhaustion, clock) not flat no.
- Pair with dnd-character plugin for sheets/builds; pull HP/AC/passives automatically before initiative.
- Manage table: spotlight rotate 15min, phone basket, 10min break hourly, recap + stars last session start.
- Worldbuild lean: 3 factions + 1 tension + 5 named NPCs + rumor table; expand only what players touch.
- Handle rules disputes in 60s: DM rules now, discuss after; check Sage Advice + errata post-session.
- Close arcs with consequence montage + loot + downtime 10 days + hook next quest + XP/milestone call.

## Examples
- Example 1: "new DM first session" -> Lost Mine Cragmaw 4 goblins balanced 4x lvl1, 3 scenes, pre-gen via plugin.
- Example 2: "combat slog" -> cut HP 30%, average damage, timer 60s, minions 1HP, boss lair action pressure.
- Example 3: "player discomfort" -> call X-card pause, fade to black veil, retcon, stars/wishes adjust.

## Workflows
- Prep workflow (60min): 3 scenes bullets -> maps/tokens -> encounter math -> loot/DCs -> secret/cliffhanger.
- Encounter workflow: Count actions -> pick CR budget -> add terrain + goal (not just kill) -> test 3 rounds.
- Session workflow: Recap 5 -> hook 20 -> twist 60 -> break -> climax 60 -> loot/downtime/hook 15.
- Safety workflow: Session0 lines -> X-card explain -> mid check -> post stars/wishes -> adjust next prep.

## Templates
- Scene prep card: Hook: goblin bounty board | Twist: hostage + timer 6 rounds | Climax: bugbear + flood trap.
- Encounter budget lvl3x4: Easy 300 Medium 600 Hard 900 Deadly 1600 XP/day ~4800 with 2 shorts.
- NPC quick: Name Kella | Quirk lisp + coin flip | Want map to crypt | Secret cultist | DC13 insight.
- Safety checklist: [ ] lines/veils list [ ] X-card visible [ ] break timed [ ] stars/wishes asked [ ] retcon honored.

## Tools

## Advanced
- Run clocks (6-segment) for chases/rituals: tick on failed check or loud action, doom at midnight.
- Design lair/boss with 3 phases + legendary 3/round + minion waves to fix solo action deficit.
- Use fail-forward: missed DC still progresses with cost (noise, injury, faction heat) never dead end.
- Scale 1-20 arcs with 3-tier villains (local lord -> cult -> god) + personal bonds per PC.
- Record table meta with Stars/Wishes log to tune horror/puzzle/combat ratio per player.
- Pull character plugin example: `!sync Tav` -> import AC 18 HP 45 passives 14 before rolling initiative.
- Run West Marches with 12 players: job board + 3 DM clocks + downtime shared world doc.
