BIOHAZARD QUEST STRATEGY
Starting location: Talk to Elena in the building east from her mother and father in Ardougne.
Quest difficulty level: Medium.
Reward: Thieving exp, permission to the kings training ground.
Quest points gained: 3.
Required quest: Part one of Plague City quest must be completed.

Elena: She will tell you to talk to Jerico, find him in a house south of the west bank. He will tell you to talk to Omart found at the southern wall.
Omart: After talking with Elena head over to Omart who will tell you that you\'ll have to talk with Jerico about something to distract the guards. Jerico will just send you back to Omart because he\'s too busy feeding his pigeons. While at Jerico, search his cupboard to find some pigeon feed, and go around back and take a pigeon cage.
Over the wall: Go to the tower north of Omart and use the pigeon feed on it, and then release the pigeons. Talk with Omart and get over the wall. Now go all the way north and take a rotten apple west of the most north-eastern house there. Now go over the fence, use the rotten apple with the cooking pot, and talk with the mourner.
Doctor: The mourner will tell you that they're all sick, so you'll have to play a doctor now. To do this you'll need a doctors gown, you can find this in the house south-west in the city where the nurse Sarah lives. Search the cupboard to get the gown. Put it on and go back to the mourner. Open the door to the building and go upstairs, where you'll find a mourner you'll have to kill.
Elena's distillator: After you kill the mourner upstairs you'll get a key. Use this on the gate over there, and search the crates in there. Go back to the place you came over the wall and get Kilron to help you over. Head back to Elena, and she'll tell you to take some samples to the chemist in Rimmington. Be careful with the samples, they will break if you teleport or fight on the way. You can put them in the bank and teleport to Falador though.
Chemist: Once at the chemist?s house a little west of Rimmington, talk with him (don't talk about the plague), and then go outside and give Chancy the liquid honey, Hops the sulphuric broline and Devinci the ethenea (in that order)
Varrock: Go to Varrock and buy a priests robe from the clothes shop if you haven?t done that already. Go to the Dancing Donkey Inn in south-east Varrock and get your samples back from the three men there. Put on your priest robes and head into the building where Guidor is. Talk with him, and he'll tell you that there is no plague. Go back and give Elena the good news, and then head over to the King for your reward.

BLACK KNIGHT\'S FORTRESS QUEST STRATEGY
Starting location: Falador, in the White knight's Castle.
Quest difficulty level: Medium.
Reward: 2500gp.
Quest points gained: 3.
Required Skills: 12 quest points.
Required Items: A cabbage from anywhere except Draynor Manor, an iron chain mail and a bronze medium helmet.
Monsters: Black Knights(31) - you only have to defend yourself for a short amount of time.
NPC: Sir Amik Varze (upstairs in the western tower of the White Knights' Castle in Falador).
Introduction: The black knights are up to no good. You are hired by the White Knights to spy on them and uncover their evil scheme.

Before approaching the castle, obtain an iron chainmail (this can be bought from Wayne's Chains in south Falador) and a bronze medium helmet (helmet shop in the Barbarian Village.) Then go to the monastery (north west of the Barbarian Village) and take a few cabbages from their cabbage patch. Next go to the Black Knights\' Castle - it's at the base of Ice mountain, on the north eastern side.
The front door is locked so you need to use the side door - the Guards\' entrance. Put on your iron chain and bronze medium helmet.
Find out about the secret plot. Upon entering the castle, push your way through the fake wall directly in front of you. Go up two ladders and you\'ll find yourself on the roof. Go down the other ladder, through the two doors to the east and then up and down the next two ladders to get over the fence. You\'re now in the altar room. Go out through the door onto the balcony and quickly down the ladder so the knight doesn\'t hurt you too much. Sneak along the secret passageway and listen at the ventilation grill. You discover that the Black Knights are brewing up an invincibility potion, but that you can save the day by putting the cabbage you\'ve collected into the cauldron, spoiling the potion. Go all the way back to the door from which you entered, and this time go through the door to your east, move quickly up the ladder onto the outer wall. Proceed around the corner and push your way through another wall. Now, use the cabbage on the hole in the floor. Make sure you don\'t eat it, or you\'ll have to go and get another.
Completing the quest: Throw the cabbage down the hole, the potion froths and bubbles, and is ruined. Go and talk to Sir Varze again and he\'ll reward you for your bravery.

Firstly talk to the gardener outside with your ghost speak amulet on. Ask him what happened to his head. He will follow you to the haunted woods. Keep talking to him and he\'ll tell you where to go. Dig his grave to find the head.
Now head back to the castle and go upstairs. Search the bookcase in a room to the west for the book Joy Of Grave Digging and you get a marble amulet, then search the bookcase in a room to the east for the Handy Maggot Avoidance Techniques and you get an obsidian amulet. Use them with each other to make a star amulet. Leave the castle and follow the path east to a graveyard and use your star amulet on the last memorial to the east. Push the monument, follow the cave round and kill the level 51 experiment. Pick the key up and head north-west. Use your key on the gate, and then go upstairs. Dig the 3 graves to get torso, arms, and legs.
Head to the pub in Canifis and talk to Roavar. Ask him for some food and buy the pickled brain by asking for something to eat. Put the brain in the head and give all the parts to doctor. He will need a needle and 5 threads. Now he will want a conductor for lightning made of silver. Go talk to the gardener and ask for the key for the shed. Go into the little room north of the gardener and search the cupboard for a garden brush, and just outside the shed door, you will see some cane piles, pick 3 garden canes. Use bronze wire to connect the canes and the brush, you need 3 canes and 3 bronze wire.
Sweep the west fireplace on the first floor of the castle to get the conductor mould, use a silver bar on a furnace to make the conductor and take it back to the doctor. You can then go through the south doors on the first floor, up the ladder and use the conductor on the rod out there.
Go back to the doctor, he'll tell you the monster is alive and you need to kill it, get the key from him, head back up to the first floor and use the key on the gate door up there to gain access to the monster.
The monster will tell you the truth about the doctor and ask you to take the Ring of Charos from the doctor. Go downstairs and pickpocket the doctor to complete the quest.

DEATH PLATEAU QUEST STRATEGY
Starting location: Speak with Denulth located in southern Burthorp (north of the Heros\' Guild).
Quest difficulty level: Medium.
Reward: 3k Attack Exp, Steel Claws and ability to make them. You can also buy climbing boots from the Sherper for 12gp each, allowing you to cross the secret path for some troll killing. They do not need to be spiked.
Quest points gained: 1.
Required Items: 10 cooked trouts, 10 pieces of bread (either cook it, steal from the Yanille Watchman or buy from players/jungle store/baker in Ardougne), 1 asgarnian ale (bar in the quest area or in Falador), 1 iron bar, might need a Blurberry Special (You can get this from the bar in the Grand Tree (Gnome Stronghold))
NPC: Dunstan (behind the castle to the east).

Denulth tells you trolls have taken over the Death Plateau and are using it to launch nightly raids, however they can?t get to invade the camp because the main path is heavily guarded. It has now become your job to find a different path to the death plateau. You also have to open the equipment storage and that requires a certain combination that a guard has.
Section one of the quest: Obtaining the combination from the Guard:
Go to the top floor of the castle, and talk to Eohric about where the guards are. He will tell you that there is only 1 guard on duty (Harold), and that he is at the Toad and Chicken Pub. Go to the pub to find him. You try and talk to him, but he doesn?t want to talk about the combination so go back and talk to Eohric. He will tell you if you buy Harold a beer he might talk to you.
Buy Harold an asgarnian ale and try talking to him again, this time he will tell you he lost the combination, and that he?s searched everywhere. Now ask him if he wants to gamble. Keep trying to bet him until you get an Iou you will only get an Iou betting in amounts between 300-1000gp, it will be on the back of the combination.
Note: If you are not winning he probably isn't drunk enough best chances if you give him a blurberry special
Head back to the castle and you'll see some stones on the ground, pick up the 5 stones and place them in this order:
Blue is far south-west, Yellow is far south-east, Red is mid-west, Purple is mid-east, Green is far north-east.
Go upstairs and talk with the archer there, he will thank you for getting the combination right.
Section two of the quest:
Walk north-west towards the Death Plateau you will find a cave. Go in and talk to Saba. Ask if he knows another path to the Death Plateau. This guy is a mean old grump, but would love to get rid of the goblins he tells you. He also tells you about a sherpas.
Sherpas? house: Go south-west and talk to Tenzing, ask for his help. He wants 10 loaves of bread, 10 cooked trout and some spiked boots in return to help you. He will hand you some climbing boots, take those to Dunstan to get them changed into spike boots. He tells you that he will make you the boots under one condition, that his son is made into an imperial guard.
Talk to Denulth (where you started the quest) and now you get to tell Denulth that you have found a new path however it will only be shown under the condition that Sherpas has spiked boots and the whole story. Denulth makes an exception and gives you a certificate to accept Dunstan?s son into the imperial troops. Now simply go back to Dunstan with an iron bar and the certificate.
Now you should have your spiked boots, go back to Tenzing and give him his supplies. Tenzing gives you a map of the secret area. You need to check the path before telling Denulth about it. Go out his door and climb over the stile and walk up the path and as soon as you see the message saying its safe, go and talk to Denulth.

Starting location: Starts in the centre of Varrock market. Go over to the red and white striped tent and talk to the gypsy inside it. She will ask you for some money, only 1 gold, to get your palm read. She will then tell you that you are the chosen one, the one who will save the whole of Varrock from a mega demon called Delrith who, whilst alive, destroyed Varrock 150 years ago. She tells you of a special sword named Silverlight, the only sword powerful enough to defeat Delrith.
Quest difficulty level: Medium.
Reward: Silverlight Sword.
Quest points gained: 3.
Required Items: 1gp, bucket/jug of water and 25 normal bones.
Monsters: Delrith.
NPC: Gipsy (Varrock), Sir Prysin (Varrock Palace), Captain Rovin (Varrock Palace), Wizard Traiborn (Wizards Tower).

Getting the sword: Go north from the tent into the castle, if you go a little North-west you will see a man named Sir Prysin, the person who is supposed to have Silverlight. He tells you how to find the 3 keys that you need to get Silverlight.
Key One: The easiest of all, go to the NW corner of the castle and go up the staircase twice, talk to Captain Rovin and he will eventually give you the key.
Key Two: Go back to the castle, go to the kitchen and through the door to the courtyard, and just to left of the exit you will see a drain. Use the bucket/jug (with water in it) on the drain and the key will fall into Varrock sewers. To get the key you have to go straight away to the sewers. To get into the sewers go out of the front of the palace and go east along a path and look out for a manhole on the right. Enter the sewers through the manhole and take the path to the north and west. Follow it to the end and find the key near a pile of bones. If you get there and the key is not there, repeat the bucket of water down the drain as above.
Note: there is a bucket respawn just above the kitchen in the palace.
Key Three: Make your way to The Wizards Tower, which is south of Draynor bank, taking 25 bones as these are needed to get the third key. Once there, go up the ladder and talk to wizard Traiborn. You can fight the wizards in the area for bones.
The Fight: After you have got all three keys make your way back to Varrock castle and talk to Sir Prysin and he will give you the Silverlight Sword. Now make your way to south of Varrock (you should see a stone circle) and fight Delrith, the correct incantation is:
