How to Make a Sapphire Lantern in OSRS

In Old School RuneScape (OSRS), the sapphire lantern is a unique light source that plays a vital role in quests like Tears of Guthix and While Guthix Sleeps. Its distinctive sapphire lens sets it apart from standard bullseye lanterns, making it essential for attracting light creatures in specific in-game scenarios. This guide will walk you through the step-by-step process of crafting a sapphire lantern, including requirements, materials, and tips to streamline your efforts. Whether you’re a seasoned adventurer or a new player, you’ll find everything you need to create this item efficiently.

The sapphire lantern isn’t just a decorative item—it’s a functional tool required for navigating dark areas and completing certain quests. Here’s why it matters:

• Quest Requirements: Essential for Tears of Guthix and While Guthix Sleeps, where it attracts light creatures to traverse caverns.
• Post-Quest Utility: Useful for activities like fighting tormented demons, as it remains a necessary light source in specific areas.
• Unique Aesthetic: Its blue glow (though not visually distinct in-game) adds a touch of flair to your inventory.

Understanding its purpose will help you prioritize gathering the materials and meeting the skill requirements.

Key Quests Involving the Sapphire Lantern

The lantern is tied to two major quests:

• Tears of Guthix: You’ll need the lantern to access the Chasm of Tears by attracting light creatures.
• While Guthix Sleeps: Required for navigating dark areas and battling tormented demons.

Without the lantern, progressing in these quests is impossible, so crafting one early can save you time.

Skill and Item Requirements

Before you start crafting, ensure you meet the necessary skill levels and have the required items. Here’s a breakdown:

Skill Levels Needed

To make a sapphire lantern from scratch, you’ll need:

Skill	Level Required	Purpose
Smithing	49	Craft the bullseye lantern frame
Crafting	20	Cut the sapphire
Firemaking	49	Light the lantern

Note: If you’re using a pre-made bullseye lantern, you don’t need 49 Crafting to swap the lens for a sapphire, making it accessible for lower-level players.

Items You’ll Need

Gather these items before heading to the workbench:

• Steel Bar: Used to smith the bullseye lantern frame.
• Hammer: Required for smithing the frame.
• Sapphire: Can be mined, purchased, or obtained as a drop.
• Swamp Tar: Needed to add lamp oil to the lantern.
• Tinderbox: Used to light the lantern after oil is added.
• Bullseye Lantern (Optional): If you have one already, you can skip some crafting steps.

Most of these items are easy to obtain from the Grand Exchange or through skilling activities like mining and thieving.

Step-by-Step Guide to Crafting a Sapphire Lantern

Follow these steps to create your sapphire lantern from scratch. Each stage is designed to be straightforward, even for beginners.

Step 1: Crafting the Bullseye Lantern Frame

Start by heading to an anvil with a steel bar and a hammer in your inventory.

1. Visit an anvil (e.g., in Varrock or Falador).
2. Use the steel bar on the anvil to open the smithing interface.
3. Select “Bullseye Lantern (unf)” to create the frame.

This requires level 49 Smithing. If you’re short on levels, consider buying an unfinished lantern from the Grand Exchange.

Step 2: Cutting the Sapphire

Next, you’ll need a cut sapphire for the lens.

1. Obtain a sapphire (mine at gem rocks, steal from gem stalls, or buy from the Grand Exchange).
2. Use a chisel on the sapphire to cut it, requiring level 20 Crafting.
3. Be cautious—cutting gems can occasionally fail, resulting in a crushed gem, though this is rare for sapphires.

A cut sapphire is also tradeable, so purchasing one is a viable option if you’re not keen on crafting.

Step 3: Adding Lamp Oil

Before the lantern can be lit, it needs lamp oil. You have two options for this step:

• Rimmington Chemist:
  1. Travel to the chemist’s house in Rimmington.
  2. Use swamp tar on the lamp still in the chemist’s house.
  3. Use your bullseye lantern (empty) on the still to fill it with oil.
• Dorgesh-Kaan Lamp Still:
  1. Head to Miltog’s market stall in Dorgesh-Kaan (requires completion of Death to the Dorgeshuun).
  2. Use swamp tar on the lamp still while the lantern is in your inventory.

The Rimmington method is more accessible for most players, as it has no quest requirements.

Step 4: Attaching the Sapphire

Now it’s time to make the sapphire lantern itself.

1. Take your cut sapphire and bullseye lantern (filled with oil).
2. Use the sapphire on the lantern to replace the lens.
3. If the lantern had a glass lens, you’ll receive it back in your inventory.

This step doesn’t require 49 Crafting if you’re using a pre-made lantern, making it a quick process for many players.

Step 5: Lighting the Lantern

Finally, light the lantern to make it functional.

1. Ensure you have a tinderbox in your inventory.
2. Use the tinderbox on the sapphire lantern (unlit).
3. Your lantern is now ready to use, casting a bright beam to attract light creatures.

Tip: If you extinguish the lantern (by selecting the “Extinguish” option), you can relight it later with a tinderbox as long as it has oil.

Tips for Efficient Crafting

Crafting a sapphire lantern can be optimized with a few strategies to save time and resources.

Buy Pre-Made Components

If your Smithing or Crafting levels are low, consider purchasing these items from the Grand Exchange:

• Bullseye Lantern (Oil): Skips the smithing and oil-adding steps.
• Cut Sapphire: Avoids the need to cut gems yourself.

This approach is especially useful for Ironmen or players short on time.

Stock Up on Swamp Tar

Swamp tar can be a bottleneck if you’re crafting multiple lanterns (e.g., for tormented demon farming). Sources include:

• Lumbridge Swamp: Use a spade to dig up tar piles.
• Monster Drops: Creatures like cave slimes drop swamp tar.
• Grand Exchange: Buy in bulk for convenience.

Reverting the Lantern

After completing your quests, you can revert the sapphire lantern to a standard bullseye lantern:

1. Use a bullseye lantern lens on the sapphire lantern.
2. You’ll recover the cut sapphire and get a regular lantern back.

This is a great way to save resources, as sapphires can be reused or sold.

Common Mistakes to Avoid

To ensure a smooth crafting process, steer clear of these pitfalls:

Forgetting Lamp Oil

Many players craft the lantern but forget to add lamp oil, rendering it unusable. Always double-check that you’ve used swamp tar at a lamp still before attempting to light it.

Not Meeting Skill Requirements

If you’re crafting from scratch, ensure your Smithing is at least 49. Otherwise, you’ll need to buy an unfinished lantern or boost your level temporarily (e.g., with a dwarven stout).

Losing the Lantern

During quests or activities like tormented demon farming, dying can result in losing your lantern. Always keep a spare sapphire and bullseye lantern in your bank to avoid being stuck without one. Some players learned this the hard way when their only lantern was lost in a grave!

Crafting a sapphire lantern in OSRS is a rewarding process that opens up exciting quest opportunities and enhances your gameplay. By following this guide, you’ll have your lantern ready in no time, whether you’re exploring the Chasm of Tears or battling demons. Gather your materials, check your skill levels, and light up Gielinor with confidence!
