Khrumbul-Dun is the third main island you’ll be introduced to in Dragon Quest Builders 2.
Unlike Furrowfield, this island is more of a mining island, with plenty of precious metals.
Here’s a pretty long walkthrough and guide of Khrumbul-Dun in DQ Builders 2.

Below is a table of content to make navigation much easier for this walkthrough.
Build a staircase
Right after reaching Khrumbul-Dun, you have to walk around to trigger the next event. You guys will fall down into a hole.
To get out, use blocks to build a staircase.
You will be introduced to the main character of the island, i.e. Babs.
Follow her back to her town.
Build a cask
Your first objective is to build a cask using wood and cord. Cord can be taken from the creeper plants.
Place the cask on the block at the bar.
Once you’re done, make a digger’s jigger at the cask, with the plant she gave you.
Follow the voice
You will then hear a voice calling out for the builder. Follow Babs.
Break through the sand wall using your hammer.
You will find a stone golem inside named Goldirox.
Craft a copper ingot
Next, you need to make copper ingot and to do so, you’ll need copper ore and coal.
Follow the miner down into the mines. Break through the wall with your hammer.
After going through, you’ll have to stabilize the props by grabbing the blocks on the ground and closing the gaps.
There, you’ll find plenty of copper ores and coal (black in color). Just mine them all.
After getting the ores, go back to town and show them.
To craft an ingot, you need to build a forge. Go to your work bench and build one.
Craft the copper ingot.
Make a cocktail counter
With the copper ingot, craft a cocktail shaker using the work bench.
Place the cocktail shaker on the connecting tables in the bar. You’ll now have a cocktail counter.
Raise the base level
Once you’re ready, raise the base level to get more recipes and recruit more people.
Build a copper bar
Your next big project is to build a copper bar. The ingredients are all stated in the blueprint.
Some of the ingredients can’t be obtained until you reach higher base levels.
It’s part of your first big mission, i.e. Going for Gold part 1.
There are 2 parts to this. You need to fix up the tunnels and build a bar.
Whenever you enter the mine, remember to activate a naviglobe if you see one, to allow fast travels.
Place 3 community chests
Next, you need to build 3 chests. Just craft them using wood.
Place the chests as shown in the marker.
Fix up the tunnel
There are many parts to fixing the tunnel. Just follow the miner first.
At one point, you’ll have to break open the walls to pave the way.
Apart from just breaking walls, your main objective is to fix the mine tracks. There are rocks blocking them, and some tracks are missing as well.
To find more tracks to take, just follow the existing track and you’ll come across stacks of unused tracks along the way.
Grab all of the unused tracks and start fixing the track route.
Build a dormitory
Next, you need to build a dormitory. For the room, you have to get at least 8 beds, pots and also the inn sign.
Build a mushroom kitchen
You also need to make a mushroom kitchen for Babs. You just need 2 bonfires, 1 community chest and a marshroom.
For the marshroom, you need to grab it (not hammer it). Grab a marshroom at the mines and bring it back to the kitchen.
Just place the marshroom anywhere, and the mushroom cookroom is done.
Place 10 sconces
Another mission requires you to place 10 sconces in the base.
Just make sconces using torches and copper ingot.
You can place them anywhere, as long as the area is within the base.
Continue exploring the mine
Your next aim is to look for iron ore. Follow the workers again.
You’ll reach another area with unstable beams. Fix them with the softwood you find on the floor.
Blast the wall open using the bomb.
Fix the scaffolding
You will find iron ore, but the scaffolding is weak.
Once again, you’ll draw a blueprint.
Fix the scaffolding accordingly.
Before you leave, activate the naviglobe for fast travel.
Build a smithy
Your next mission is to build a smithy. To do so, you need iron blocks, a pot, a sack, a chest and a new forge.
Grab some iron ore first and turn them into iron ingots.
Once you have iron ingots, you can make iron blocks. Your smithy needs to have iron blocks as the wall.
The forge, pot, community chest and sack must be within the walls.
Make a sledgehammer
After unlocking iron ingots, you can build a new sledgehammer to pummel harder material. Use the anvil.
Once you have the sledgehammer, go back to the mine and break through the hard material.
Stop the water
You will reach a place with underground water, but it’s flooded. You have to stop the water.
Get to the marked area and start building blocks to patch the holes on the ground. The water will stop filling up.
Continue fixing up the tunnel
Once you get to the next area, keep fixing up the tunnel.
You will meet a group of monsters. Defeat them.
You will then come across more tracks to grab. Hammer them all to grab them.
Start placing the tracks again.
At this point, there are two different tracks to fix. You need to fix both of them.
Once you’re done, then this mission is complete.
After leveling up the base again, you will have enough recipes to craft all the items for the copper bar as well.
Build a gym
Your next side mission is to make a gym.
You need to craft dumbbells and so on.
Just build the room according to what he needs and you’re done.
Build a room for Babs
You also need to build a room for Babs. In order to do so, you need to lay out the blueprint.
Also, build it within your base, near the copper bar to be safe.
After laying out the blueprint, just place the ingredients as shown.
To get the Gladiolus flower, you need to look for the grassy area on your map with a small pond. It’s probably north of the town.
Just use your gloves and carry it back.
Place the flower on the pot, and the room is ready.
Defeat the intruders
You will be intruded by some Children of Hargon monsters for the first time.
Defeat them all.
Build a silver bar
The next big project is to build a silver bar on a new land.
It’s quite a huge task as you need to get plenty of iron blocks and silver bricks. Just place them according to blueprint.
Ride the giant and look for silver
To look for silver ore, you need to ride on the giant and get to the marked area on the map.
You will use him to punch through huge walls.
At one point, he goes back to town. Continue ahead with the worker.
Again, there’s a naviglobe here. This is the Old Lift Naviglobe if not mistaken.
Light the path
The worker will then ask you to light the path using a torch.
On the way, there are plenty of monsters to defeat.
At the end, there’s another naviglobe.
You will find silver ore just nearby.
Mine some silver ores and get back to town.
Make a bar counter
You will get a request to complete the bar counter at the silver bar first.
Place connecting counters, stone stools, a cocktail shaker and a water jug, all according to the same silver bar blueprint.
Make a frying pan
Babs will ask you to make a frying pan. Use iron ingot and wood to craft it.
Place the frying pan on the bonfire inside the mushroom kitchen and you’re done.
You can now cook meat and mushroom on the same pan.
Build a shower room
The next request is to build a room for shower.
Craft a shower from the work bench.
The wall of the shower room has to be lined with silver blocks.
Also, put a towel and a folding screen, and you’re done.
Find more veins of silver
Continue your hunt for more silver. Meet the worker at the mine.
You will then stumble upon someone looking for three of her brothers.
Search for the brothers
You need to look for the brothers. The locations are all shown on the map. The first brother is surrounded by mobs.
Defeat them all.
The next brother is hidden behind walls. Break through the walls with your hammer.
Continue looking for the third brother. You will come across a place filled with gigantic marshrooms.
To climb up, you need to destroy some of the marshroom heads, and grab them.
Place the marshroom heads at the marked areas on your screen, while you climb up.
You will find the third brother at the top.
Continue looking for silver veins
Next, continue the search for silver veins. You need 3 in total. The areas are all marked on the map.
Just whack through the walls.
Build a swimming pool
Back at the base, you’ll be asked to make a pool at the silver bar.
Just use your bottomless pot and pour water.
Make a relaxation room
You also have to build a relaxation room. For this room, you need a bed, a curtain, one folding screen and dim lighting.
This means you’ll probably need just one torch.
Defeat the enemies (2nd time)
The Children of Hargon will come again to disturb you guys.
Take them all out.
Find the other half of the echo flute
After defeating the enemies and Goldirox turning silver, he’ll give half an echo flute to you.
It’s used to find all kinds of precious metals. You need to find the other half.
Meet the worker at the mine.
Follow him until you reach a place filled with gold walls. Activate the naviglobe again.
Solve the puzzles
You will see a big room with statues. Two of them are missing.
Before the room, there are 2 doors. One is open. Go through it.
You will come across a puzzle area.
It’s pretty easy. You just need to bring the red box to the blue tile. If you press pull on walls with the red sign, it will pull the individual red box to it.
To solve it, build blocks to block it, and then press pull.
Next, create another block to stop its path and press pull again to reach the blue tile.
You will get a key. Hold the key to open the lock.
You will come across another room with 3 treasure boxes. Avoid the box in the middle.
If you open the middle, you’ll meet a monster.
Now, get to the other room and you’ll encounter another puzzle.
Just pull the individual red box all the way here.
Move it to the side first, and move it to the same row as the blue tile, by putting a block on the wall.
Next, create another block right beside the blue tile. Press pull again and it will reach the blue tile.
After solving the puzzle, continue ahead. You may encounter silver scorpions.
Keep going and you’ll meet more monsters.
Go until you find the 1st statue. Destroy it to take it.
Now, you should have a gold key from the chest in front of the statue.
Go back to the start and open the door on the other side now.
More scorpions here.
Enter a room with a stone monster. To defeat it, use your hammer, not your weapon.
Grab the key from the chest.
Use the key you took earlier to open the next door.
You will find yet another puzzle. This time, it’s flooded.
To get rid of the water, build blocks around the waterfall. Use your bottomless pot to drain the water.
Also, destroy the blocks of sand blocking the ‘red pull walls’.
Like before, you need to reach the blue tile.
Just pull the red box all the way to the other side. Put a block to get it on the same row as the blue tile.
Next, put another block behind the blue tile, and start pulling the red box.
Now, continue ahead. Look for the road with many masks on the wall. It will ask you to turn back, but you can ignore.
Just keep going ahead despite it asking you to turn back multiple times.
The last statue is here. Take it back.
Place the statues
Go back to the start and place the statues to where they should be.
They will come to life. Defeat all the statues using your hammer.
Finally, you’ll get a flute fragment after defeating the statues.
Craft an echo flute
Go back to town to craft an echo flute using the work bench.
Find gold ores
Go back to the mine to look for gold ores. Just play the flute and follow the musical notes.
Dig through and you’ll find gold nuggets.
Find veins of gold
Next, you need to find more veins of gold. Continue using your flute at the lower level and you’ll easily find another.
In this room, you’ll see a blue creature. Talk to it to get hints on where the next vein is.
You can go back to where you found the gigantic marshroom to look for gold.
The exact location is shown in the map below (lower level).
You will find the last gold vein here.
Extend the shower room
Your next job is to make the shower room bigger.
Like before, you can continue using silver blocks. This time, have at least 4 showers, more folding screens and more towels.
Also, create some windows in the toilet. Add torches as well to bring light.
Build a new dormitory
You then need to build a new dorm for the workers.
Build it near the silver pool.
Like before, you need 8 beds. Put some pots and the sign as well.
This dormitory has to reach 3 stars for fanciness.
You can add a couple of brazier lights to increase fanciness.
After building the dorm, you will learn a new recipe to make light boxes.
Complete the silver bar
After learning the light box recipe, you can finally complete the silver bar.
Create three boogie boards
Next, make three boogie boards for Babs.
You can make them with wood.
Place the boogie boards on the stage.
Babs didn’t really want boogie boards, but something else. Ordelia suggested to make a huge billboard for Babs on the silver bar.
To make it, you need zenithium.
Get to the lower level to find zenithium.
Talk to Jules again to get hints.
She’ll say head east into the tunnel. The exact location of the zenithium is shown in the map below.
Just get there, use your echo flute to pinpoint the exact spot. Follow the blue-colored music tunes.
Start digging downwards and you’ll find these zenithium ores.
Build Babs’ billboard
Get back to your work bench to construct the billboard.
Place the billboard at the top of the silver bar stage.
Defeat Children of Hargon (3rd time)
For the third time, defeat the enemies.
It’s slightly harder this time with rock monsters. Use your hammer to kill them.
Babs then performs her dancing, but gets turned into stone by Madusa.
Build a gold bar
After Babs is turned into stone, you have to build a gold bar to boost morale of workers and to lure Madusa out in the open.
The blueprint is much bigger this time, but you don’t have to do it alone. Similar to making the Deitree, the workers here will do most of the work.
You only need to place fifty gold brick blocks correctly and the rest will be done by the workers.
Find red dye
However, you need to look for red dye, to turn the light boxes into red.
Follow the marker on the map. You’ll find yourself on a cliff. Use your windbraker to get to the next island.
There’s a naviglobe here as well. Defeat the slime enemies as you get here.
Once the coast is clear, mine the red dye.
Make red light boxes
Go back to town to make red light boxes. Before that, you need to build a dye machine.
Use the machine to change the color of the light boxes to red.
Place the red light boxes according to the markers.
Find blue dye
The second level of Gold Bar will be constructed. This time, you need to find blue dye.
Go to the upper level of Khrumbul-Dun and head towards the underground water as indicated in the map.
As you get there, you’ll meet a creature. Talk to it and it’ll ask you to dive into the water.
Keep swimming underwater towards the next area. When you surface, you’ll see blue dye here.
Make blue light boxes
Bring blue dye back and turn the light boxes into blue.
Place the blue light boxes in the marked areas.
Next, you’ll need diamonds for the 3rd level of the Gold Bar blueprint.
Use your echo flute here and you’ll be led to a nearby location.
Goldirox will break open a huge hole to the bottom.
Jump inside and try to use your windbraker to shield the impact.
As it’s hot, the windbraker keeps getting destroyed, but you can keep using it to slow the momentum.
Get through the magma
After entering, just walk following the safe ground. Go one big circle.
You will reach a dead end with a signboard. To keep going ahead, use your bottomless pot and pour water into the magma.
Pouring water into magma will create solid ground. Keep going ahead and doing the same thing.
Keep going until you reach a naviglobe.
Continue using water to make a pathway. You should encounter this enemy on the way.
At one point, you can just build blocks instead of using water because the platform is higher.
You will come across the 2nd naviglobe.
You will also come across this unique place with enemies.
Defeat the enemies
Take on the enemies and defeat them all.
Use your echo flute and you’ll find yourself behind the magma-fall.
Keep hammering the wall until you find some diamonds.
Create golden gauntlets
Bring the diamond back to town and craft golden gauntlets for Goldirox.
He’ll use it to deflect Madusa’s stone powers.
Build a Goldinoggin
Next, you need to build a Goldinoggin to lure Madusa out.
Place the Goldinoggin at the top of the Gold Bar.
Defeat the underlings
Before you can face Madusa, you need to defeat her underlings first.
Finally, you’ll have to take on Madusa. Remember to equip everyone who can wield weapons with the best swords.
To start the fight, you need to climb on Goldirox first. You’ll be controlling him.
The fight isn’t tough, but time consuming. Use the gauntlets to block her stone-turning powers. You’ll be informed when she wants to use that power.
After it deflects back at her, you can keep punching her to reduce the HP quickly.
In between, she’ll summon many monsters to help her. Just whack them like normal.
At one point, she’ll turn into two. One is fake.
Just look out for the white beam. You can ignore the other colors.
Madusa will also use an aerial attack at one point. Keep moving to avoid getting hit.
At the last stage, she’ll create two fakes instead. Just concentrate on the one with white beams.
After defeating Madusa, you’ll get a heartstone.
Create a Golden Glow
Go to your work bench to craft a Golden Glow, using the heartstone, silver ingots, gold ingots and copper ingots.
Goldirox will disappear and blends with Khrumbul-Dun as the guardian of the place. The mines will be filled with precious metals again.
Recruit people back to the Isle of Awakening
Before you leave, talk to some of the folks and recruit them back to your island.
When you’re ready, head back to the Isle of Awakening with your new friends.
And that’s all on Khrumbul-Dun in Dragon Quest Builders 2.
