OSRS The Knight's Sword Quest Guide: Mine Blurite ore safely

The Knight’s Sword is a short but iconic quest where you help the Squire replace Sir Vyvin’s lost ceremonial sword—without Sir Vyvin ever knowing. The quest is quick, gives a massive early Smithing boost, and is beginner-friendly as long as you’re careful inside the Blurite cave.

Difficulty: Intermediate

Length: Short

General Questing Tips: Enable the RuneLite Quest Helper plugin for step-by-step guidance. Hold spacebar to skip dialog and use number keys for response options. Bring food before entering the Blurite cave—Ice Warriors hit surprisingly hard if you’re low-level.

Skill Requirements

• 10 Mining
• Ability to survive attacks from:
  • Ice Warriors (Lvl 57)
  • Ice Giants (Lvl 53)
    

Item Requirements

For normal accounts

• Redberry pie
• 2 iron bars
• Any pickaxe
  

Recommended Teleports

• 1 Varrock teleport
• 3 Falador teleport
• 2 Mudskipper point teleport: Rat-pits minigame teleport,  teleport to house, falador teleport, or Fairy ring AIQ

These save several minutes of running

Ironman tips

• Redberry Pie: Make it by adding redberries to a pie shell and cooking it
• Iron bars: You’ll find it north of Ferox Enclave in the Wilderness. Keep an eye out for PKers — I had to hop worlds twice to find a safe one. If you don’t want to risk it, you can just mine iron ore and smelt it into iron bars with coal instead (15 Mining required).

• Pickaxe: Any pickaxe works; I used a steel pickaxe for speed.

Time to Complete

I finished the quest in about 7 minutes. New players should expect roughly the same if they follow the safe mining method shown below.

Walkthrough of The Knight’s Sword

Start the Quest

Recommended: Falador teleport

• Teleport or run to Falador then talk to the Squire in the Falador Castle courtyard indicated by the quest icon in image below 
• During the dialog, choose 1 → 2 → 1 → 1 to offer your help. He suggests asking Reldo about Imcando dwarves.

• Tip: If you’ve already completed The Giant Dwarf, your character automatically knows who Thurgo is, and you can skip Reldo entirely.

Speak to Reldo (Varrock Castle Library)

Recommended: Varrock teleport

• Teleport or run to Varrock and talk to Reldo who hangs out in the north room of the Varrock Library as indicated by quest icon below.
• Talk to Reldo about the imcando dwarves and he will point you to the Mudskipper point.

Visit Thurgo the Imcando Dwarf

Bring: Redberry pie

Recommended: Mudskipper point teleport and falador teleport to start next section

• Before you go, make sure you have a redberry pie.
  If you’re planning to do The Giant Dwarf soon, bring two pies to avoid another trip.
• Teleport to Mudskipper point with any of these method: Fairy ring AIQ, Rat-pits minigame teleport, teleport to house (Rimmington), or falador teleport.Talk to Thurgo, south of Port Sarim, indicated by the quest icon in the image below. 

Choose dialog option 2 to offer him the pie. He’ll help you only after eating it.

Getting the Portrait

Recommended: Teleport to Mudskipper point for next section

Head back to Falador Castle and chat with the Squire again. Then, go upstairs:

• Climb the east ladder

• Head west into Sir Vyvin’s area

• Go up the staircase

Finally, search the southern cupboard.

Quick heads-up: make sure Sir Vyvin isn’t in the room when you search the cupboard. If he is, either wait, hop worlds, or walk into the next room until he wanders off.

Mining Blurite (Safely)

Bring: A portrait, 2 iron bars and pickaxe

Recommended: food, if low level or prayer potion, Mudskipper teleport, and Falador teleport to finish quest

• Return to Thurgo and give him the portrait (choose reply 1).

• Now you need to mine a Blurite from Blurite rocks. Climb down the ladder northeast of his hut, highlighted below to enter the Blurite Cave. All monsters here are aggressive, so bring food if you don’t have Protect from Melee.

Identifying Blurite:

• Blurite rocks are bright blue—super easy to spot

Safe Mining Method (Highly Recommended)

• The cave has ice spikes on the floor. Stand behind them while mining to prevent the Ice Warriors or Ice Giants from reaching you since they will get stuck.

• You take zero damage while mining.

 I mined the blurite ore with 10 Mining in about 15 seconds using this method.

Additional Tip

If you plan to complete the Falador Easy Diary, mine one extra Blurite ore now.

Finishing the Quest

Return to Thurgo with:

• 1 Blurite ore
• 2 iron bars
  

Choose reply 1 to have him forge the sword.

If you want a Blurite sword for yourself:

• Drop the first sword
• Ask Thurgo for another
• Pick the dropped one back up
     

Finally, return to the Squire in Falador Castle to complete the quest.

Congratulations — Quest Complete!
