Underground Pass RS3 Walkthrough - Slaying Iban

By Helen Gray | Created: July 21, 2023 | Last updated: December 17, 2024 | Read Time: 14 minutes

Welcome to DivicaSales Blog Series!

Hello readers! We're back once again to the DivicaSales blog series. Within this article, we will discuss the RS3 Underground Pass quest, looking at the requirements, rewards, and more. So, without further delay, let's get into it! 

What is the Underground Pass RS3? 

The Underground Pass in RS3 is a quest named after the location where it takes place. After being sealed for thousands of years, it has been reopened. The reopening uncovered a labyrinth of tunnels and chasms that are complex to navigate. 

The quest itself is members-only and is categorized as long/very long in terms of official length. So if you're up for the challenge, prepare to buckle down and start the long and tedious journey that is the Underground Pass RS3.

If you want to know how to get through Underground Pass RS3, you'll need to first understand the requirements, so let's get into it.

RS3 Underground Pass - Requirements 

Fortunately, there aren't many quests you will need to have completed in order to start this quest, meaning you won't need to put in too much groundwork. You'll need to have done the Biohazard and Plague City quests. 

Similarly to the quest requirements, the skilling requirements should be easily met, as you'll only need to be 25 Ranged.

As for item requirements, there are a few more of those, though not many. So we have compiled a list below. 

  • A rope
  • A bow 
  • Arrows (ogre, god, broad, araxyte, wild, dark, and ice are not suitable)
  • Free inventory for the items received

Now that we've covered the requirements for the quest let's take a look at the recommendations; though these are not vital, they will prove helpful. 

Underground Pass RS3 - Recommendations 

Having the following can significantly reduce the difficulties you face during this quest. However, you can still happily proceed without them if you wish to use them; they are as follows: 

  • 50 Agility 
  • 43 Prayer 
  • 50 Thieving 
  • Armor and weapons (preferably ranged/magic)
  • 1000 coins 
  • Agility potions/summer pies 
  • Emergency teleport 
  • Plank 
  • Catspeak amulet 
  • Daves spell book with chipped Ardougne teleport

We would also recommend that you enter this quest with no pet or follower, as a particular part of the quest causes you to freeze; your only way of escaping this situation is teleporting, undoing progress.

Now we've covered the quest recommendations, let's take a look at who exactly we'll be facing through the duration of this RuneScape adventure! 

Which Foe Will You Face in RS3 Underground Pass?

As with many RS3 quests, you must take down some enemies throughout. So, let's take a look at those: 

  • Kalrag
  • Sir Harry 
  • Sir Jerri
  • Sir Carl
  • Doomion 
  • Othanian 
  • Holthion 
  • Disciple of Iban 

Now we know who we're up against, let's get into the methods of this Underground Pass quest guide in RS3.

How to Get Started in Underground Pass RS3

Speak with The King

The starting point of this quest is the first floor of the Ardougne Castle; here, you'll need to speak with King Lathas. You will learn that King Tyras, Lathas's brother, has abandoned his post as reigning king of West Ardougne and moved further west. You must then ask the king if his scouts were able to carve a path through the mountain. He will tell you they have by uncovering an ancient tunnel.

The downside to this discovery is that the tunnel is filled with cultists who follow the evil Lord Iban, the alleged son of Zamorak. The king will then ask you to check in on Koftik, the king's tracker. He will be waiting for you at the entrance to the tunnels on the West Ardougne side. 

Hawk Eye

Now that it is known the plague was just a ruse and you can enter West Ardougne through the main gate, do so. Make your way to the far west side of the city until you locate the cave entrance, where you will find Koftik. When you speak with him, he will inform you more about the pass before telling you to meet him inside beside the bridge.

Upon entering the dungeon, you will see three paths that branch into three different directions. Try to avoid the center path, as this can cave in beneath you, causing some hefty and unnecessary damage. 

After taking one of the paths, you must then climb over the rockslides and go around the swamp, after which you should see Koftik standing by a fire. Converse with him; he will say it looks like others have already been exploring the caves as he located a damp cloth and a book.

Take an arrow and use the damp cloth on it, then right-click to "light arrow" before equipping a bow and arrow. You'll then need to make your shot to continue. To do so, head to the small room north of you and look over the chasm. You should be able to see the guide rope which is holding up the drawbridge; click on it to fire your arrow. You'll know you have succeeded if the drawbridge drops and you're able to continue forward. 

On Grid, Off Grid

For the next part of this Underground Pass RS3 quest, head south, and you should come across a second fork in the road. Make sure to take the eastern path. Taking the southern path will result in being sucked into the swampy area. On your journey down the eastern path, you'll see stone tablets inscribed with messages on how to proceed safely. Take note of these. 

You'll then need to use a Trollope accompanied by the "old spike" located on your side of the pit to make a balance beam rope to walk over. Try not to fail; doing so will see you have to begin again from the beginning of the pass.

Once you succeed, carry on across the rock slides until you spot Koftik, who will be standing before a grid of mesh. Speak with him, and it will become apparent his mental state is unraveling slowly as he hears voices.

Your next task on the RS3 Underground Pass journey will be to dictate which of the grid squares will support you and which will drop you into the pit below. Each drop will cause 150 damage, so try to be cautious. If you do find yourself in the pit, there are protruding rocks within the pit that you can use to escape. 

Ensure to memorize the grid squares that support you, as you will come back on this path later in the quest. Once you do find the correct path and make it to the other side, pull the lever on the south wall to pass through the gate. 

Lights in the Night

Next, for our Underground Pass RS3 walkthrough, you'll need to locate the furnace to the north of you. You won't need to use it just yet, but make sure you're aware of its location. You should also see a one-way agility path that shortcuts back to the beginning; west of you will also be a narrow corridor. 

Approach the corridor with caution; there will be five traps located within the walls. Two are on the northern border, and three are on the southern. Having higher thieving can help you with disarming these traps, and failing to do so can cause 560 life points to be lost for each trap. Another method (though still posing its own risks) is to stand one square before a trap and then quickly run past. Though this can be successful, the danger is still prominent, so be cautious of your losses.

Keep in mind that while in the pass, the Surge ability is disabled, so that option isn't available when passing traps. 

No matter your chosen method, you'll eventually reach an area with a less-than-welcoming well at the center. There will be a book and an altar located close by; additionally, a stone tablet will reveal the message, "If a light should break the night, the dark will rise to win the fight." 

You'll need to next ensure that your life points are at a suitable level, so either eat, use rapid, or rapid renewal while you wait. Once you're satisfied with your life points, begin praying at the altar. 

The next step in this Underground Pass RS3 guide is to explore the four paths before you. Keeping in mind the "flat rock" pressure plate traps ahead. 

Northern Path 

Use your plank on each of the flat rocks to bypass traps, it is possible for those of a higher thieving level to disarm the traps, but as failure is still possible, you can entirely avoid it using the plank. 

Once you're past the traps, you should find an Orb of Light at the end of the tunnel; collect it before returning. 

North-West Path 

This passage will see you encountering level 42 Blessed Spiders and level 67 Ogres. You can choose to fight or bypass, whichever you see fit. Collect the second orb and make your way back. 

Midwest Path 

This path is similar to the northern path, but you will have to navigate past five traps rather than three. Use your plank once again to get by and collect the orb before returning. 

South West Path

This final path will see you having to face the trap within. You will be able to approach the orb unscathed, but you must undo the trap before you pick it up. Without doing so, a log will swing from above, inflicting varying damage depending on current life points. 

With your four orbs obtained, head back to the aforementioned furnace, remaining cautious of the traps you have yet to disarm. Place each of the orbs into the furnace to destroy them, and you will then be able to climb down the well.

Don't Look Down

Once down the well, you'll find yourself by three crates. Searching the middle one will reward you with two salmon and two meat pies. You should also find a rope respawn point nearby.

Continue on deeper into the cave; you'll see you're surrounded by cages. Take the passage ahead of you, which leads to a dead end; this will force you to find an alternate way of moving forward. 

On the southern wall, go to the cage furthest east and pick the lock. You will notice a bizarre-looking patch of mud in the back of the cage, dif through the patch with a spade, and you'll encounter a hidden tunnel that will take you to the other side. Make your way across the narrow ledge, and you should enter a space near a maze of raised beams.

It's worth noting that falling from the beams will deal 50 damage, so be cautious. There are ramps nearby if you do fall, in which case, make your way back up to the beams and find your way across. Once you have completed the maze, head south and pass through the obstacle pipe, then make your way to the next area. 

Slaughtered 

At this stage in our Underground Pass RS3 quest guide, you'll locate a unicorn in a cage. Search until you find a loose piece of railing. From here, make your way south down the path until you locate a boulder. 

Using the loose railing, dislodge the boulder. This will kill the unicorn allowing you to return to the wreckage of the cage and retrieve the unicorn horn. Afterward, you must head north and go through the tunnel; here, you will encounter a small group of Paladins in a makeshift campsite. 

The Paladins, named Sir Carl, Sir Jerro, and Sir Harry, are all of level 81. Speaking with Jerro will see him giving you the following: 

  • Loaf of bread x2
  • Meat pie x2
  • Bowl of stew 
  • Prayer potion x2 
  • Attack potion x2

This generous act still does not take away from the fact you'll need their badges. To do so, you'll have to slay the Paladins. 

Be cautious, however, as they respawn. So you can try trapping them by safe-spotting them behind the rocks surrounding you. 

Now, with the three badges (red, green, and blue) in tow, make your way west. Remain vigilant, as there are more flat rock traps there, so you'll need to use your plank or your preferred method to pass. Continue on past this point until you find another well. 

The well will read, "Feed me three crests of the blessed and the creature's remains." So you'll need to use the three Paladin badges and unicorn horn on the well; doing so unlocks a large door.

Cornucopia 

Now we're coming toward the endgame of the Underground Pass RS3 quest; there are some potentially frustrating steps ahead. 

You'll enter an expansive cavern, which has rock ledges edging the perimeter. This open area has a maze of walkways for you to navigate, many of which are permanently broken. Falling from the maze’s paths can result in large damage hits and see you in a pit of the soulless. Try to keep your food in your inventory unless you're entirely out of options.

What you're about to embark on has no official requirements, but the lower your agility level, the harder you'll find the journey. However, it is still very possible to complete the quests maze, even at level one. 

For the moment, do not enter into the walkways. Instead, head as far south as possible until you reach the south wall. Once there, go slightly west until you locate some stairs. Upon walking down them, you will encounter Koftik. He will appear before you rambling nonsense while also informing you some dwarves are now residing there and are immune to Lord Iban's power before vanishing. 

The Tale of Lord Iban

Continue onward into an opening of a fenced area where you will see three dwarves named Niloof, Klank, and Kamen. Niloof will provide you with food when you speak with him; if more is needed, you can speak with Kamen, who has an unlimited supply of meat pies, stews, and bread for 75 coins each. 

Niloof will inform you of a witch called Kardia; she holds the secret to killing Iban. After receiving this information, you'll need to climb the staircase again and head northeast. You will be led to the southernmost of all the walkways. Walk over this path to Kardias house. By listening outside her window, you should hear her talking to herself about her missing feline friend. If you open the door, you risk losing 900+ life points, but if you wish to avoid the damage, click away and end the conversation. 

So, next on your agenda will be locating the cat, and to do so, you'll need to head north before going west over the bridge gap. There will be a north branch of the path; take it. Continue along this route until you find a platform, at which point you'll want to check your minimap. Make your way toward the yellow dot and retrieve the witch's feline friend. 

With the cat in tow, return to Kardias home and use the cat on the door. The action will automatically hide you behind a corner while the pair are reunited. While she is distracted, you'll need to sneak into her house and find the chest to search. 

Searching this chest should leave you with the following:

  • Restore potion
  • Super attack potion 
  • History of Iban
  • Doll of Iban 

The book was written by Kardia herself; read it and locate the information on how to take down Iban. Ending him must be done in the exact manner in which he was resurrected. This means collecting four of his life elements; Flesh, Blood, Shadow, and Conscience. Once you have done so, imbue them with his effigy, and when this is done, you will finally be able to destroy him. So, let's break down the steps to do that.

Endgame Approaching - Killing Lord Iban 

Within this segment of our Underground Pass RS3 guide, we're going to walk through how to obtain the needed items, use them, and destroy Iban and his reign. The first to collect will be the Shadow. 

Iban’s Shadow

To do so, you'll need to slay three level 78 demons, Doomion, Othainian, and Holthion, and retrieve their amulets. Once you have all three, open the chest which was closest to Doomion and open the chest. This will destroy the amulets but release the Shadow, which you must then use on the doll.

Once you have done so, return to the dwarves and speak with Klank to receive Klanks Gauntlets. Once you have those, grab a bucket from the large building and make your way to the smaller one. 

Iban’s Flesh

Next, you must use your bucket on the barrel inside to acquire Dwarf Brew. Take it and head to the far southeast corner where the tomb of Iban is, dumping the bucket of alcohol into the tomb and lighting it with your tinder box. Once the fire has burnt out, you should see Lord Iban's Ashes left behind in your pack.

Iban’s Blood 

Your next endeavor in the Underground Pass RS3 quest is to obtain Iban’s blood. To do so, surpass the soulless until you reach a corridor riddled with Blessed Spiders; walk to the end of the enclosed area, and find the level 81 spider Kalrag. She was the one to feed on Iban's blood, meaning you'll have to slay her to smear his blood on the doll. 

Ensure you make a swift exit, as the smell of the blood will draw other spiders to attack. 

Iban’s Conscience 

The final step of imbuing the doll is to gain his conscience. To do so, you must locate a dove killed by Kardia; it represents the innocence of Iban's soul before evil corruption took hold. 

You'll find the dove inside an old wooden cage amongst many cages that have half soulless within them. The dove is in one of the cages at the center of the area. Ensure you're wearing the Klank Gauntlets, as while you search cages, the half soulless will bite at you. When you finally acquire the skeletal dove, use it on the doll. 

The Final Strike on Lord Iban

With the effigy ready, make your way to the Iban’s temple, which is at the heart of the cavern. When you're close to entering the temple, kill a Disciple of Iban in RS3 and wear the Zamorak robe outfit (red); ensure you're wearing nothing but the outfit for entrance to the temple. 

Your next objective in this RS3 Underground Pass guide is to use the doll on the well in the middle of the room, a simple task in theory, however, not in practice. Iban will sense your and the doll's presence and begin casting spells in your direction. Each strike he lands will inflict 100+ damage to your life points, so it is recommended you get as close to Iban as possible. 

When in his closer vicinity, he deals fewer spikes, so we recommend doing this and then running when there are no spells in practice. If you're of a high level with good defense, you may be able to simply go to the well and take the hits, but if this is not the case for you, try the above method of running between attacks. 

Upon throwing the doll into the well, Iban will be obliterated, and the temple will begin to fall. You will also be teleported out with your rewards; ensure you have the inventory space if you don't want to lose the Runes. 

Once this has taken place, you will be in a cavern with Koftik, who has found his sanity after Iban's hold has been diminished. Exit the cavern toward Tirannwn, where Koftik will lead you to the entrance for you to head back to East Ardougne to speak with King Lathas and complete the quest.
