The Barrel of Naphtha is a quest-specific item in OSRS, tied to two notable quests: Regicide and Mourning’s End Part I. It’s a volatile substance derived from coal tar, distilled with coal, and used either as an explosive or a solvent. Weighing a hefty 32 kg, it’s one of the heaviest items in the game, making it a literal burden to carry—but its utility far outweighs the inconvenience.
Role in Quests
In Regicide, the Barrel of Naphtha is a key component in crafting a barrel bomb to destroy King Tyras’ camp. Meanwhile, in Mourning’s End Part I, it serves as a solvent to create a toxic mixture that furthers the quest’s storyline. Its dual-purpose nature makes it a fascinating item for players exploring the elf-related questlines.
Why It Matters
Beyond its quest significance, the Barrel of Naphtha showcases OSRS’s intricate mechanics. The process of crafting it involves a mini-game-like distillation sequence, testing your patience and precision. For lore enthusiasts, it ties into the darker, alchemical side of Gielinor’s narrative.
How to Craft a Barrel of Naphtha in OSRS
Crafting a Barrel of Naphtha is no simple task—it requires preparation, specific items, and a keen eye on the distillation process. Here’s a step-by-step breakdown to ensure you get it right the first time.
Items You’ll Need
- Empty Barrel: Found in Tyras Camp or the orchard south of the Tree Gnome Stronghold.
- Coal Tar: Collected from the Poison Waste swamp south of the Tirannwn lodestone.
- 6-10 Pieces of Coal: Mined or purchased from the Grand Exchange.
- Access to Rimmington: Where the Chemist’s fractionalizing still is located.
Step-by-Step Crafting Guide
- Gather Coal Tar: Head to the Poison Waste in Tirannwn. Use an empty barrel on the tar to obtain a Barrel of Coal Tar.
- Travel to Rimmington: Bring your Barrel of Coal Tar and coal to the Chemist’s house.
- Start Distillation: Use the Barrel of Coal Tar on the fractionalizing still outside the Chemist’s house.
- Adjust the Valves:
- Turn the right valve twice (to the third tick) to maximize tar flow.
- Watch the pressure gauge on the left. When it hits the green zone, turn the left valve once (to the middle) to stabilize it.
- Add Coal:
- Monitor Progress: The bottom bar will turn green as the naphtha distills. Once full, close the interface to claim your Barrel of Naphtha.
Tips for Success
- Don’t Overheat: Adding too much coal too quickly can ruin the batch, forcing you to start over.
- Bring Extras: Carry multiple barrels and extra coal in case of failure—it saves a trip back to Tirannwn.
- Practice Patience: The process is finicky, but steady adjustments will get you there.
Using the Barrel of Naphtha in Regicide
In the Regicide quest, the Barrel of Naphtha is your ticket to blowing up King Tyras’ forces. Here’s how to wield its explosive power effectively.
Crafting the Barrel Bomb
Once you have your Barrel of Naphtha, you’ll need additional items to turn it into a bomb:
- Pot of Quicklime: Made by heating limestone in a furnace (wear gloves to avoid damage) and grinding it with a pestle and mortar.
- Ground Sulphur: Grind sulphur (found during the quest) with a pestle and mortar.
- Strip of Cloth: Weave 4 balls of wool on a loom (e.g., in Falador).
Mix the quicklime and sulphur into the Barrel of Naphtha to create a Naphtha Mix, then add the cloth to finalize the Barrel Bomb.
Executing the Plan
Take the completed Barrel Bomb to the catapult in Tyras Camp. Use it to launch a fiery assault, advancing the quest. Precision in crafting is key—any misstep could mean trekking back for more materials.
Barrel of Naphtha in Mourning’s End Part I
In Mourning’s End Part I, the Barrel of Naphtha takes on a different role as a solvent, contributing to a sinister plot in West Ardougne.
Creating Toxic Naphtha
You’ll need:
- Apple Barrel: Made earlier in the quest by filling a barrel with rotten apples.
- Sieve: Provided by Elena during the quest.
Use the Barrel of Naphtha on the Apple Barrel to create a Naphtha Apple Mix. Then, use the sieve on the mix to produce Toxic Naphtha.
Finishing the Poison
Cook the Toxic Naphtha on a range (not a fire—fires cause explosions!) to create Toxic Powder. This non-lethal poison is used to make West Ardougne’s residents ill, fulfilling the quest’s objective.
Common Mistakes and Troubleshooting
The Barrel of Naphtha process can be tricky, and many players stumble along the way. Here’s how to avoid pitfalls and fix issues.
Distillation Fails
Problem | Solution |
---|---|
Pressure in Red Zone | Turn the left valve to relieve pressure, then stabilize it in green. |
Heat Overheats | Add coal slowly—wait for the gauge to drop before adding more. |
Progress Bar Stalls | Ensure the right valve is fully open and pressure is in green. |
Quest Item Mishaps
- Lost Barrel: If your naphtha disappears post-quest, it’s likely a game mechanic—craft a new one.
- Wrong Cooking Method: Use a range for Toxic Naphtha, not a fire, or face explosive consequences.
