**Module:** _White Plume Mountain_ (1979)
**Location:** Room 27 – _Kelvin’s Cairn_ area
**Why It’s Famous:** Merges riddle-solving, magical deception, physics-based traps, and high stakes in a unique dungeon room.

## 🏞️ Setup — What the Players See
> _As you enter the cavernous chamber, heat slams into you. Before you, a massive bubble of shimmering force encloses a floating black ziggurat. Boiling mud churns violently below it. Inside the dome, weapons hover in mid-air, suspended above the ziggurat’s highest tier. A narrow ledge winds around the perimeter of the bubble, with a small arched opening leading into the dome itself._
### Environment:
- **Room:** 60 ft. wide, 100 ft. long chamber
- **Floor:** Boiling mud (lava-like, but viscous; 6d10 fire damage on contact)
- **Dome:** Magical **force bubble** surrounds the ziggurat (can be entered through one archway—no exit once inside except same way)
- **Ziggurat:** 3-tiered obsidian structure **floating in mid-air** about 10 ft. above the mud
- **Weapons:** 9 total, floating 5 ft. above the top tier

## ⚔️ Puzzle Core – The Weapons
Nine weapons float in the air. Only **one** is real—the others are either illusions or trapped decoys.
### Weapon List (randomise if desired):
1. Flame Tongue sword
2. Frost Brand
3. Trident of Fish Command
4. Spear of Backbiting
5. Greataxe
6. Dagger
7. Longbow
8. Morningstar
9. Warhammer
> One of these is the **target weapon**—in the original module it was _Wave_, the intelligent trident. You can change this to a weapon relevant to your story.
### Important:
- Grabbing the **wrong weapon** causes the **force bubble to disappear**.
- The ziggurat and any characters on it **plummet into the boiling mud**.
- Mage Hand, ropes, or testing the weapon first can avoid instant death.

## đź§ The Riddle
On the wall just inside the bubble entrance is a glowing inscription in Draconic:
> _“Nine arms reach, but only one bears truth.
> One sings with the sea.
> The others bring only death.”_
> _(Players who speak Draconic or use Comprehend Languages can read it.)_
### Interpreting the Riddle:
- "Nine arms" = Nine floating weapons
- "One bears truth" = Only one is real and safe to touch
- "Sings with the sea" = Clue pointing to the **trident**

## đź§Ş Investigation Options
Encourage creative thinking. Here’s how common actions play out:
|Action|Outcome|
|---|---|
|**Mage Hand**|Illusions pass through; real weapon is lifted (success)|
|**Poke with pole/arrow**|Illusions pass through; some emit fake resistance|
|**Detect Magic**|All weapons glow faintly (illusion magic), but real one has additional enchantment|
|**Arcana DC 15**|Realises multiple illusions, but illusion aura overlays them all|
|**Perception DC 18**|Sees faint shimmer around 8 weapons (illusion flicker)|
|**Insight DC 15 (reading riddle)**|“Sings with the sea” = trident|
|**Touch wrong weapon**|Bubble disappears instantly; ziggurat and everyone fall into boiling mud|
---
## đź’Ą Trap Mechanics
### If the wrong weapon is grabbed:
- The **bubble vanishes** instantly
- The **ziggurat drops** 10 ft. into the **boiling mud**
- Anyone on it:
- **Dex save DC 18** to jump to safety (if near the edge)
- Otherwise, fall into mud: **6d10 fire damage per round**, until escape (extremely difficult)
Use tension and countdowns here. Players should feel the urgency if they make a mistake.

## 🧙 DM Tips – Running the Puzzle
- **Reward caution and cleverness**. Players using _Mage Hand_, identifying illusions, or referencing the riddle should bypass the trap safely.
- Don’t be afraid to **telegraph the danger**—heat rising, dome flickering slightly, mud burbling ominously.
- If players are struggling, give small passive clues (e.g., illusion weapons flicker if someone casts _Light_, or real one drips with water magically).
- Add **waves of heat damage** if players linger too long (1d6 fire damage/round outside the bubble).

## 🧾 Handout Option – The Riddle
You can present this as a note or wall carving:
---
**🗡️ Wall Inscription:**
> **Nine arms reach for glory, but only one bears truth.**
> **It sings not with fire, frost, or fury—**
> **but with the whisper of waves.**
> **Grasp false strength, and sink with it.**

## âś… Solution Summary
- **Correct Weapon:** The Trident
- **Correct Method:** Use _Mage Hand_, _Detect Magic_, or riddle interpretation
- **Wrong Action:** Grabbing any other weapon causes a deadly fall
- **Exit:** The same archway is the only way out—if you survive
