Description: The black knights are up to no good. You are hired by the white knights to spy on them and uncover their evil scheme.
Difficulty Level: Hard
Items/Skills Needed To Start: 12 quest points, Bronze Medium Helmet, Iron Chain Mail
Starting Location: Second floor of White Knight's Castle
Reward: 2500 coins and 3 Quest Points
Instructions:
Go talk to Sir Amik Varze in the White Knight's castle in Falador. He's upstairs. He'll tell you what you have to do.
Before you head to the Black Knight's Castle which is North of Ice Mountain, retrieve iron chain mail and a medium bronze helmet from anywhere (make them if you have to). Then head over to the monastery east of Black Knight's Castle. Pick a cabbage from the field behind the monastery. Then head to the Black Knight's Castle.
Put on your iron chain and your bronze medium helmet. Walk through the side door on the east side of the Castle. Then head north inside that little room and push on the odd-looking wall. Go up the ladder.
Go up to that grate and listen in. The witch will talk to the black night about the secret weapon which is an invincibility potion. The little goblin is supposed to fetch that special cabbage. But he won't! :-)
Head back down the stairs. Go through the door westward where the Black Knights are. The guard will tell you not to because those Knights will kill anyone who comes in. Go in anyways.
If any knights attack you (level 46) just run away or kill them. Then head into the south room. Go upstairs, and then climb that ladder west of you.
Once upstairs and up the ladder, go north and push against another odd-looking wall. Then use that cabbage you got on that hole. Now you should have destroyed the witch's magical potion. Good for you!
Head back to the White Knight's Castle and talk to Sir Amik Varze for your reward!
