BLAK KNIGHTS FORTRES
In city of Falador, visit the White knights castle, and talk to Sir Amik Varze upstairs. He'll tell you of the Black knights planning to destroy the white knights with some secret weapon. Your task is to find out what it is, and sabotage it. Go to the Cabbage field beside the monastary and take 1 or more cabbages, then go to Black Knights Fortress (a bit west of Monastary) You'll notice the front door is locked, and the guards won't let you in the side door. Why? You don't look like them. To get in u need a Guards uniform, Medium Bronze Helmet and Iron Chainmail After getting in go through the "odd looking wall" which is at the north Wall when u get in, go up the ladder. You see a "Grill" and u can choose listen by left clicking it, u will see the Black Knight Goblin, and the witch will start to speak to each other. It's an invincibility potion they're making, and it needs a cabbage from Draynor Manor to be complete. Any other cabbage will destroy the potion Go back down the ladder, you see a room next to you with 3 Black knights, try to go in and one of the Guards tells you that you shouldnt go in there, because the black knights are gonna attack you. When u get in there, 1 Black Knight will attack you, but just run from the fight or kill the Black Knight if u can. If u press the other door in the room, a Black Knight will attack u, so make sure all Black Knight's are busy if u want to go thru the door, (good to get friends with u attacking the BK's). Go upstairs, climb the ladder, at the north wall is a "odd looking wall". Go through it and "use cabbage with hole" (Make sure you "use" cabbage not eat it like i've done countless times) If you made it correct u will say "that must have ruined the secret weapon" or something like that. Reward: 2500gp, 3 quest points
