The conduit block in Minecraft allows players to breathe underwater, gain night vision, and mine blocks faster while underwater. Making a conduit can transform your underwater builds and make ocean exploration much easier. In this comprehensive guide, we will cover everything you need to know about conduits including what they do, how to craft them, and how to activate their powerful effects.
What Does a Conduit Do in Minecraft?
A conduit is a block that provides several advantageous effects when fully activated. Here are all the benefits you gain from a working conduit:
-
Underwater Night Vision – Players near an active conduit gain night vision, allowing easy visibility when deep underwater. The night vision effect has a range of 96 blocks horizontally from the conduit.
-
Underwater Water Breathing – Nearby players will gain the Water Breathing effect allowing you to breathe underwater infinitely near a powered conduit. This also works in bubble columns.
-
Increased Mining Speed – When underwater, players gain Haste 2 which speeds up mining by 30% for all nearby blocks including ones above the conduit.
-
Attack Boost – You deal +2 extra attack damage when hitting hostile mobs near an active conduit while underwater.
So in summary, a fully-powered conduit dramatically improves the underwater gameplay experience. You unlock incredible utility like infinite breathing, rapid mining of underwater/ocean monuments, and high visibility – making conduits extremely useful end-game blocks.
How to Craft a Conduit in Minecraft
Crafting a conduit requires finding some rare underwater items and arranging them in a specific pattern in a crafting table.
Here is the conduit recipe:

As you can see, these are the required materials to craft one conduit:
- 8 Nautilus Shells
- 1 Heart of the Sea
So first, you need to acquire these crucial components.
Finding Nautilus Shells
Nautilus shells are dropped items when you kill drowned mobs in ocean biomes. Drowned have a small chance of dropping 1-3 shells when defeated. They spawn in deep ocean biomes during the night so the best way to farm nautilus shells is sailing to ocean areas at night and defeating drowned zombies.
Alternatively, you can find shells in ocean ruins treasure chests as loot. So raid submerged monuments to collect extra shells!

8 shells for one conduit may take some time to gather so be patient!
Getting the Heart of the Sea
Heart of the Sea items are very rare, only found in treasure chests buried at deep depths underneath buried treasure blocks. You must first get treasure maps (trade with cartographer villagers) which show visual X marks indicating treasure locations.
Dig down at the X to uncover buried treasure chests which have a chance to contain the Heart of the Sea (among other epic ocean loot!). You may have to search several buried treasures before acquiring your first heart.

Once you finally gather all the crafting materials, open a crafting table and arrange them in the conduit pattern! This provides one conduit block which you can place underwater.
Activating the Conduit‘s Effects
Simply placing down your conduit will not activate its effects. To unlock all the buffs mentioned earlier, you need to construct a particular multi-block structure around the conduit using prismarine blocks.

Here are the required steps:
- Place your conduit block where you want the effects (underwater!)
- Build a hollow + shaped prismarine structure with a 3×3 hole around the conduit. Must be at least 2 blocks high.
- Fill inside with water sources. You can use kelp to quickly create water sources!
- Activate with prismarine blocks – see specifics below.
You must activate the conduit by placing prismarine blocks on the 4 corner sections, shown in lighter color above.
The game counts prismarine blocks diagonally from conduit to corners. You need at least 16 total prismarine blocks placed with a minimum 1 prismarine block on each corner section.
However, more prismarine blocks will extend the conduit‘s horizontal working range. Place up to 42 on each corner to reach the max 96 block effect radius.
So in summary:
- Base Activation: At least 16 prismarine blocks total, with 1 on each corner section touching conduit structure
- Increased Range: Add more prismarine blocks diagonally on corner sections (max 42)
Once activated, you‘ll see a beam shoot to the sky indicating the conduit turned on!
Additionally, you can check the conduit‘s current working radius by looking at its block – it displays a number from 0 to 96 reflecting horizontal range.
Maintaining Conduit Activation
To keep your conduit continually working, it must have water sources directly exposed to its hollow center column and no barriers blocking the beam vertically.
Here are key points for maintenance:
- Ensure water flows into the conduit chamber from the sides
- Use kelp to quickly transform still water into water sources
- Don‘t cover up the 3×3 center hole
- Avoid placing blocks above the conduit beam emission point
As long as both activation conditions are fulfilled (prismarine blocks + water access), your conduit provides stellar advantages as you explore the seas!
Finding Prismarine for your Conduit
You may be wondering where to acquire all the prismarine blocks required for activating conduits. After all, you require at least 16 prismarine but likely more.
There are a few options for obtaining prismarine:
Mine prismarine blocks – You can mine prismarine directly inside ocean monuments which spawn in deep oceans. Use an efficient pickaxe to harvest prismarine blocks and kill monument guardians.
Craft prismarine – Combine a prismane shard with quartz to craft prismarine. Get shards and crystals as drops from monument guardians. Use quartz from the nether.
Convert materials – Craft prismarine using dark prismarine blocks acquired when clearing monuments. Or smelt prismarmor blocks from elder guardians.
So essentially, raiding ocean monuments allows you to utilize both the direct prismarine blocks found inside as well as collect resources to craft more!
Just be well equipped to defeat the monument mobs – elder guardians and guardians which have nasty thorns attacks. Once cleared, harvest away all the glorious prismarine!
Conduit Building Tips and Tricks
Here are some helpful pointers when working with conduits for your underwater buildings and adventuring:
- Mark buried treasure map destinations to unlock heart of sea items in future worlds.
- Build underwater rails connecting conduit waypoints to fast travel.
- Combine with beacons for even stronger effects!
- Craft a respiration helmet so you can mine out the conduit chamber.
- Use magma blocks near conduits when building farms – deals damage to mobs but not players!
- Get efficient tools like a diamond pickaxe for quick mining and defeating guardians.
Awesome Conduit Designs and Creations
With your newfound conduit powers, there are unlimited possibilities for oceanic works. Here are just a few examples of conduit-enhanced builds:
Underwater City – Build a glass underwater habitat with conduit stations powering the entire city district! Gives you speed and breathing bonuses anywhere inside.
Ocean Monument Upgrade – Integrate conduits into an ocean monument farm to make building/farming much easier with their buffs.
Submarine Fleet – Construct sub-ships complete with interior conduits allowing seamless exploration anywhere underwater, especially deep waters.
Guardian Farm – Power a customized ocean monument guardian XP grinder with conduits to rapidly mine and kill guardians.
So put on your creative thinking cap and build incredible submarine worlds with the aquatic help of conduits!
Conclusion
Thanks for reading this comprehensive guide explaining conduits inside Minecraft. We covered how conduits provide superpowers like fast mining and enhanced vision underwater when fully activated.
You craft conduits using rare ingredients like nautilus shells and the heart of the sea. Then encase with a prismane block structure to unlock awesome effects up to 96 blocks horizontally.
Conduits forever change ocean gameplay by mitigating the risks of no air, slow mining, and darkness when deep diving. Unlock their potential by following the tips outlined here.
Now get building amazing underwater bases and monuments supported by conduit capabilities! The ocean awaits…
