Underground Pass

Difficulty level: Hard and long, Members Only

Reward: 5 Quest Points, Staff of Iban, 30 Fire Runes, 15 Death Runes, 3000 Agility experience, 3000 Attack experience, and ability to use Iban Blast spell.

Skills needed: Level 25 Range. Must be able to beat level 98 Demon, 2 level 78 Demon's. Must have completed Biohazard Quest. Good Agility and Thieving is an advantage.

Items needed: Any bow, any Arrow, Rope, Armor, Food, Spade and Tinderbox.

Start: Talk to King Lathas in the castle in Ardougne.

Koftik: Go into West Ardougne, go all the way past the graves and Zombies until you come to a cave, where Koftik is. Talk to him. Cave: If you look at your map on the screen, you will see 3 paths, left, right and middle. Do not walk the middle path to swamps. Instead, read the rock on the side first, then climb over the rocks on the side paths, climb until you reach a bridge and talk to Koftik again.

Bridge: Koftik will give you a piece of cloth, warp the cloth around a arrow and light it on fire or use a tinder box. Go around the small hill to the North to the grill. Wield your bow and the lit arrow and fire at the guide rope.

Swamp: After you crossed the bridge, mine some rocks near the lever there. Take also the plank. You will come to a gap. Use rope on the swing above you to cross it. Continue on, climbing small rockslides, until you come to a Floor Tile Puzzle. Talk to Koftik waiting for you there.

The Floor Tile Puzzle: This is the path that worked for me, your path can be different!
Row 1: 4th tile form the south.
Row 2: 4th tile from the south.
Row 3: 3rd tile from the south.
Row 4: 3rd tile from the south.
Row 5: 3rd tile from the south. 
Pull the lever and go on, ignoring Zombies and the furnace for now.

Odd Markings: Stop before the narrow passage. This is the tough place. If you are a good thief, search the Odd Markings to get past the traps. If your thieving is low you'll have to just run through. Note there are 5 of traps! Don't let your hit points drop down too much! Now continue until you come to 4 Passages and a central well. Grab the old journal and read it.

North Passage: Lay a plank on the flat rocks to pass them. You will not loose your plank. Get the Orb and lay your plank again down to get back.

Northwest Passage: Go past the enemies (level 53 Ogres) and pick up the Orb. There are no traps here.

West Passage: Disarm the traps on rocks with your plank and pick up the Orb.

Southwest Passage: Search the flat stone under orb, when you try to pick up the orb of light it will ask you if you want to disarm it. If you fail you will get hit by a swinging log. If you succeed - return back to the well. 

Return to the room with the furnace (yes, past the 5 Odd Markings!) Throw all Orbs into furnace.

Well: After you've thrown the Orbs into the furnace, go back and climb down the well. Search the crate for food. Continue on and pick-lock the first cage to the South. Use your spade on the mud and climb down. At the end of the path, cross the ledge.

Agility obstacles: If you are level 50+ thieving, you don't need to go across the bridges, just go South, picklock the cage and pass the swamp avoiding bubbles. It bypasses all the agility obstacles. Otherwise, go east, fight your way across the piles of rocks and bats. If you fall, it hurts, about 17 - 20 hits.

Unicorn: Squeeze through the obstacle pipe to get to the Unicorn cage. Search the Unicorn Cage for a Piece of Railing. Go around to were a boulder is. Then use Railing Piece to move the Boulder. Go back down, and search the smashed cage for the unicorn horn. Pass through the tunnel.

Paladins: Continue on past the Zombies and Undead-Ones. Talk to Sir Jerro the Paladin, he will give you food and a prayer potion. Now kill all 3 Paladins, as they drop the Paladins' Badges (crests). Continue down the path and use the plank on the flat rock to disarm it. Use the Unicorn Remains and Crests on the flames of Zamorak well (Note! This is the well you use your Iban staff on to recharge it once you have finished the quest and have used all the charges!)

Zamorak's area: Go through the door. Go South and find the Cave Stairs that will lead you down. You will have a short chat with Koftik about Dwarves.

Dwarves and the Witch: Head extreme southwest and talk to the dwarves. They will tell you about a witch. Leave the dwarves, go east and ascend the stairs. Go South to find a Witch who guards a chest (S-E corner). Don't try to open the door (-20 HP)  but search the window. You'll hear the witch is looking for a cat.

The cat: Go west and find the Witch's cat. To find it go north, than west, again north, again west - here's the cat. Now go back to the witches hut, use the cat on the door or knock on the door. While she is playing with the cat, sneak in and open the chest. You'll find a doll, a book and some potions.

The doll: Now you will need four items to use on the doll: Iban's shadow, flesh, conscience and blood. Go to the place where you found the cat. Head southwest and kill the 3 Demons (Othainian, Doomion anf Holtion, all level 91) and get their amulets. Open the nearby chest for the Iban's Shadow. Smear it on the Doll. 

Go down (using the stairs, or simply try to fall down) and continue Southwest to Dwarves again. Klank will give you Klank's Gauntlets - wear them. You can also receive food from Kamen, just accept the drink he offers. Now take a bucket and use it on a barrel is a small house to get Dwarf Brew. Go East to Iban's Tomb. Use Dwarf Blew on it and then set it on fire with a tinderbox. Take Iban's Ashes and smear it on the doll. You won't need the tinderbox and the bucket anymore.

Head Northeast, find the cave full of spiders. Go inside and kill Kalrag Spider (level 89) for Iban's blood. You will automatically use it on the doll. Go Northwest, up a pile of mud. Wear Klank's Gauntlets and search cages for Iban's Dove and then smear onto doll.

The Final Battle: Go back down the east wall until you come to the middle bridge, use it and complete the agility obstacles until you come to the Iban Disciples (level 13). Kill some Iban disciples until you get a pair of Zamorak robes, put them on and take everything else off. (make sure you have about 3 empty inventory slots) 

Approach the temple; you must be wearing nothing but the Zamorak robes in order to enter. Iban will be sitting at his throne with a well in between you and him, and he will notice that you have the only item that can destroy him� the finished doll. Iban will start to blast spells at you! They look like long roots coming up and down out of the floor very quickly. Approach the well hopefully dodging the spells; if you get hit by a spell you will be hit medium-low damage and there is a possibility you will be taken back to the start of the room. If you do make it however, use the doll with the well and Iban will die. 

You will be flung into a small cave area, in your inventory you will notice you have the Staff of Iban, 30 fire runes and 15 death runes. Walk up the path to find Koftik talk to him and you will find he has recovered from being possessed. You tell him that Iban is dead; he will say to go tell the King. Exit out the pile of rocks and you will appear at the start of the Underground Pass. Exit the cave and go tell King Lathas. You report to the King that Iban is dead and he will congratulate and reward you.
