The Black Knights’ Fortress quest pits you against the nefarious Black Knights, who are plotting to destroy the White Knights of Falador with a secret weapon. Your mission, assigned by Sir Amik Varze, is to infiltrate their stronghold, uncover their plans, and sabotage their efforts. It’s a straightforward quest with no skill requirements, making it accessible to all players, though it does require 12 quest points to start.

Quest Prerequisites

Quest Points: 12 (earned from completing other beginner quests like Cook’s Assistant or The Restless Ghost)
Combat Readiness: Ability to evade or survive attacks from level 33 Black Knights

Required Items

You’ll need just three items to complete this quest, all of which are easy to obtain:

Iron Chainbody: Purchase from Wayne’s Chains in Falador for 210 coins or smith it with 26 Smithing.
Bronze Medium Helmet: Buy from Peksa in Barbarian Village for 24 coins or smith it with 3 Smithing.
Cabbage: Pick one from the Edgeville Monastery or the farm south of Falador (avoid Draynor Manor cabbages—they won’t work!).

Starting the Quest: Meeting Sir Amik Varze

To kick off the Black Knights’ Fortress quest, head to Falador and locate the White Knights’ Castle in the city’s center. Climb to the 2nd floor (3rd floor in US terms) of the western tower, where you’ll find Sir Amik Varze. Speak to him, and he’ll brief you on the Black Knights’ suspicious activities. He needs a spy to infiltrate their fortress, located north of Ice Mountain, and destroy their secret weapon. Accept his mission, and he’ll hand you a dossier that self-destructs after reading—cue the Mission Impossible vibes!

Tips for Starting Out

Before leaving Falador, grab your iron chainbody from Wayne’s Chains (south of the castle) if you haven’t already. This saves time later. If you’re low on health or supplies, stock up on food from the nearby market.

Step-by-Step Walkthrough

With your items in hand, it’s time to infiltrate the Black Knights’ Fortress. Follow this detailed walkthrough to navigate the fortress and complete your mission.

Step 1: Gathering Your Items

First, ensure you have all required items:

Pick a cabbage from the Edgeville Monastery (northeast of Falador) or the farm south of the city.
Equip your iron chainbody and bronze medium helmet—these act as your disguise to enter the fortress.

Note: Cabbages from Draynor Manor are cursed and will ruin your mission, so stick to the recommended locations.

Step 2: Reaching the Black Knights’ Fortress

The fortress is located north of Falador, just past Ice Mountain and west of the Edgeville Monastery. From Falador, head north through the Dwarven Mine area, then veer northwest. You’ll spot the imposing fortress surrounded by aggressive level 33 Black Knights. Run past them to the southern entrance, marked by a sturdy door guarded by knights.

Step 3: Infiltrating the Fortress

Equip your iron chainbody and bronze medium helmet before approaching the door. The guards will mistake you for one of their own and let you pass. Once inside:

Push the false wall directly in front of you.
Climb the ladder twice to reach the top floor.
Head south and climb down the ladder.
Go through the eastern door, then climb up the next ladder.
Climb down the eastern ladder, proceed south through a door, and climb down again.

You’re now in a small room with a grill on the eastern wall—your spying spot.

Step 4: Eavesdropping on the Plan

Right-click the grill and select “Listen-at.” You’ll overhear a conversation between a witch and her goblin assistant, Greldo. They’re brewing an invincibility potion, and the final ingredient is a cabbage from Draynor Manor. Any other cabbage, like the one you have, will ruin it—perfect for your sabotage mission.

Step 5: Sabotaging the Secret Weapon

Retrace your steps back to the entrance using the same ladder route. From the main floor:

Head east and attempt to enter the dining hall. A guard will warn you about an important meeting, threatening death to intruders. Choose the brave option (“I’m going in anyway”).
A Black Knight will attack—run past and climb the northern ladder.
Move east, then south, and push another false wall to reveal a hole above the witch’s cauldron.
Right-click your cabbage and use it on the hole (don’t eat it!). A cutscene shows the potion being ruined.

Step 6: Reporting Back to Sir Amik Varze

With the Black Knights’ plans foiled, return to Sir Amik Varze in Falador. Teleport if you have the runes, or walk back through Ice Mountain. Speak to him to claim your reward and complete the quest.

Tips and Tricks for Success

Here are some pro tips to make your Black Knights’ Fortress quest experience seamless:

Avoiding Combat

The Black Knights are aggressive and hit hard for low-level players. Wear decent armor (like steel) in non-disguise slots (legs, shield, etc.) and bring food if your combat level is below 30. Run, don’t fight, unless you’re confident in your skills.

Item Management

Keep an extra cabbage in your inventory in case you accidentally eat the first one. Right-clicking to “use” it on the hole is key—left-clicking defaults to eating it.
