Campaign Preparation

Before the First Session

1. Read the adventure overview

   • Preferred play style (combat/roleplay/exploration)

Before Each Session

1. Review last session notes

Session Structure

Opening (5-10 minutes)

Recap last session:

• "Last time, you defeated the goblins..."
• "You're currently in the Cragmaw Hideout..."
• "Your quest is to find Gundren Rockseeker..."

Set the scene:

• Where are they now?
• What time of day?
• What's the immediate situation?

Get player input:

• "What's your first action?"
• "Who's taking point?"

Middle (Main Gameplay)

Alternate between:

• Combat: Tactical battles with stakes
• Exploration: Discovering locations, solving puzzles
• Roleplay: NPC interactions, party dynamics

Keep momentum:

• Cut boring travel: "After 3 hours, you arrive..."
• Move between scenes: "As you leave the inn..."
• Use cliffhangers: "You hear footsteps behind you..."

Closing (5-10 minutes)

Natural stopping point:

• After a major encounter
• Arriving at a new location
• Before a big decision

Wrap-up:

• "Great session! Here's where we are..."
• "Next time, you'll explore the castle..."
• "Any questions or things I should know?"

Running Encounters

Combat Encounters

Before initiative:

1. Query monster stat blocks from adventure book
2. Describe the scene: terrain, lighting, enemies
3. Roll initiative for monsters (or use average)

During combat:

1. Narrate actions: "The goblin lunges!" not "He rolled 15"
2. Track HP and status: Keep notes on damage and conditions
3. Use monster tactics: Smart enemies use cover, focus fire
4. Describe hits/misses: Make combat cinematic

Example:

DM: "The goblin archer (AC 13, 7 HP) looses an arrow at you.
     That's a 16 to hit - does it hit your AC?"
Player: "Yes, I'm AC 14."
DM: "The arrow strikes your shoulder for 5 piercing damage.
     The goblin cackles and ducks behind the rock."

After combat:

• Describe aftermath
• Allow looting and healing
• XP/milestone advancement

Social Encounters

Prepare NPC personality:

• What do they want?
• What's their attitude toward the party?
• What information can they provide?

Play the NPC:

• Use distinct voice/mannerisms
• Have goals and motivations
• Don't just exposit - make them interactive

Example:

DM: "Sildar Hallwinter is grateful you rescued him. He's a
     human warrior in his 50s, gruff but honorable. 'You have
     my thanks, friends. Those goblins were taking me to their
     boss - some bugbear named Klarg.'"

Exploration Encounters

Describe environment:

• What do they see/hear/smell?
• Any obvious features or dangers?
• What can they interact with?

Ask for actions:

• "What do you do?"
• "Who's checking for traps?"
• "Do you open the door?"

Reward investigation:

• Perception checks reveal details
• Investigation finds clues
• Creative thinking gets bonus info

NPC Management

Creating Memorable NPCs

Quick personality formula:

• Voice/accent: Gruff, high-pitched, formal, slang
• Mannerism: Fidgets, intense eye contact, laughs nervously
• Goal: What do they want from the PCs?
• Secret: What aren't they saying?

Example NPCs:

• Gundren Rockseeker: Enthusiastic dwarf, talks fast, obsessed with his mine
• Sildar Hallwinter: Serious warrior, protective, speaks formally
• Halia Thornton: Smooth merchant, knows everyone's business, always has an angle

NPC Knowledge

What NPCs know:

• Query adventure book for NPC stat blocks
• Review their background and motivations
• Note what information they can share

What they don't know:

• Avoid omniscient NPCs
• Make players work for information
• NPCs can be wrong or misinformed

---

Improvisation

When Players Go Off-Script

Stay calm:

• This is good! Players are engaged
• You don't need to know everything
• Make a ruling and move on

Improvisation techniques:

1. Ask questions:

   • "What does that look like?"
   • "How do you do that?"
   • "What are you hoping to achieve?"

2. Use the adventure structure:

   • Redirect to main quest hooks
   • "You hear rumors about Phandalin..."
   • Make their detour lead back to the story

3. Roll with it:

   • Their creative solution works? Awesome!
   • They avoid an encounter? That's smart!
   • They create a new subplot? Develop it!

4. When you don't know:

   • "Let me check the book..." (query CandleKeep)
   • "That's a great question - I'll rule X for now"
   • "What do you think would happen?"

Making Up Content

When you need to improvise:

• NPCs: Use simple personality (greedy, helpful, suspicious)
• Locations: Describe 2-3 sensory details
• Encounters: Use stat blocks from similar creatures
• Lore: Keep it vague, add details later

Example:

Player: "I want to talk to the blacksmith."
DM (thinking: There's no blacksmith in this section...):
    "Sure! You find the smithy near the center of town. The
    blacksmith is a dwarf woman named Thora. She's hammering
    a horseshoe and barely looks up. 'Need something?'"

Rule Adjudication

Core Principles

1. Keep the game moving: Don't pause for 10 minutes to look up rules
2. Be consistent: Apply the same ruling each time
3. Rule in favor of fun: When in doubt, let cool things happen
4. Defer complex lookups: "I'll check between sessions"

Common Rulings

Advantage/Disadvantage:

• Grant advantage for good ideas or clever approaches
• Impose disadvantage for difficult circumstances
• Don't stack - it's either advantage, disadvantage, or neither

Ability Checks:

• DC 10: Easy
• DC 15: Medium
• DC 20: Hard
• DC 25: Very Hard

Rule of Cool:

• If a player has a creative idea that's mechanically questionable but awesome, let it work (this once)
• "You want to swing from the chandelier and dropkick the goblin? Roll Athletics... 18? You do it!"

When to Say No

Safety and comfort:

• Respect player boundaries
• No PvP without consent
• Skip uncomfortable content

Game balance:

• Don't let one rule break the game
• "That's too powerful for 1st level"
• Offer alternative approaches

Pacing and Engagement

Keep the Game Moving

Cut the boring parts:

• ❌ "You walk for 8 hours..."
• ✅ "After a day's travel, you reach..."

Use montages:

• ❌ Detailed shopping for every item
• ✅ "You stock up on supplies and head out"

Time pressure:

• Add urgency to decisions
• "The room is filling with water..."
• "The goblins will return soon..."

Vary the Tempo

Fast-paced:

• Combat
• Chases
• Timed challenges
• "What do you do?!"

Medium-paced:

• Exploration
• Standard roleplay
• Investigation
• "You can look around..."

Slow-paced:

• Character moments
• Major decisions
• Planning
• "Take your time..."

Player Engagement

Spotlight rotation:

• Give each player moments to shine
• Ask quieter players directly: "What is [character] doing?"
• Let different skills matter

Build tension:

• Describe danger before it strikes
• Use dramatic pauses
• Make consequences matter

Reward creativity:

• "That's a great idea!"
• Grant advantage or lower DC
• Let unusual approaches work

Common Pitfalls

Avoid These

❌ Over-preparing: You can't predict everything ✅ Flexible prep: Know the story, improvise details

❌ Railroading: Forcing players down one path ✅ Multiple paths: Let players find their own way

❌ Adversarial DMing: DM vs. Players ✅ Collaborative story: You're on the same team

❌ Ignoring the book: Making up everything ✅ Use the book: It's there to help you

❌ Perfectionism: Getting every rule right ✅ Good enough: Keep the game fun and moving
