STEP BY STEP
Follow the chapters below. Click any screenshot or diagram to view it at full size.
Talk to Sir Amik Varze, who can be found on the 2nd floor (UK) west wing of White Knights' Castle in Falador. Ask him for a quest, and he will tell you that he needs a spy to infiltrate the Black Knights' Fortress. The Black Knights claim to have developed a powerful new secret weapon, and he wants you to find it and sabotage it. He will hand you a dossier (requires a free inventory space). Read it and it will self destruct, signifying the start of the quest.
If you still need the required items, on the way to the fortress you can purchase an iron chainbody from Wayne's Chains to the west of the southern entrance to Falador, a bronze med helm from Peksa in Barbarian Village, and a cabbage may be taken from the Edgeville Monastery.




Make your way to the Black Knights' Fortress, located north-east of the Dwarven Mine and the Oracle, and north-west of the Monastery. Run through the Black Knights outside the fortress; they will be aggressive to players under 67 combat. Equip the Iron chainbody and Bronze med helm to disguise yourself as a Fortress Guard before entering through the southern door (you may enter with anything equipped in any of the other slots). Alternatively, equipping a black full helm, black platebody, and black platelegs/black plateskirt to disguise yourself as a BlackKnight will work.
Throughout the following steps, there will be numerous black knights that will attack you. While in an area without any, make sure you have healed up and read ahead to the next steps to quickly pass them.
In this small room, there will be a grill. Click on it to listen. You will overhear a conversation between the Black Knight Captain, a witch and a goblin. The witch is talking about an invincibility potion she has been working on - she needs Greldo the goblin to retrieve the final ingredient to complete it, a special type of cabbage grown only in Draynor Manor. She mentions that any other type of cabbage would wreck the potion.

Return to the entrance of the building and enter the room directly east; after entering, the guard will warn you the Black Knights inside are in the middle of an important meeting, and will try to kill anyone that interrupts it. Click the option saying you don't care to enter the room, and then climb the ladder on the northern wall.
Walk around the upper, L shaped landing, and Push the wall open. Right-click your cabbage so that you do not eat it, and use it on the hole. A cutscene will play showing the potion being destroyed by the cabbage.
Return to Sir Amik Varze, and tell him you sabotaged the weapon.
