What is Conduit Power?
Conduit Power is a status effect you get from standing near an active conduit while you’re in water or rain. It rolls three underwater perks into one: you breathe normally, you see clearly in the dark water, and you mine faster. For anyone building an ocean base, exploring a monument, or draining a shipwreck, it turns the ocean from a hostile place into somewhere you can actually work.
The effect has no potion and no other source. The only way to get it is to build and switch on a conduit, then stay within its range. Once you leave the water or step outside the range, the effect counts down and fades after a few seconds.
This guide covers what the effect does, how to build the conduit that produces it, how far it reaches, and the mistakes that leave players wondering why their brand-new conduit isn’t doing anything.
What Conduit Power does
While the effect is active and you’re underwater, you get three benefits at once:
- Water breathing, so your air bar never drops and you can’t drown.
- Improved underwater vision, which brightens the murky blue and lets you see as if you had night vision below the surface.
- Faster mining, from a Haste-style boost that speeds up how quickly you break blocks.
There’s a fourth benefit that isn’t part of the status effect but comes from the same block. An active conduit attacks hostile mobs near it. Any hostile mob within 8 blocks of the conduit takes 4 damage (two hearts) every two seconds, as long as the mob is in open water and the conduit has a clear line to it. Drowned that wander toward your base get chipped down without you lifting a finger.
One thing to keep straight: the three effects only apply while you’re actually touching water or standing in rain. If you carve out an air pocket inside your ocean base, step into it, and expect to keep mining at conduit speed, you won’t. The effect needs water or rain contact to stay on.
The conduit also doubles as a bright light. An active one gives off a light level of 15, the same as a fully lit torch cluster, so it lights up the water around it and looks like a small underwater sun. That glow is handy for finding your way back to base and for keeping the immediate area free of the darkness that mobs spawn in.
The mining speed catch
The Haste part of Conduit Power speeds up mining, but it doesn’t remove the penalty for breaking blocks underwater. By default, mining underwater is five times slower than on land. Conduit Power’s speed boost helps, but it fights against that penalty rather than erasing it.
To mine at full speed underwater you want the Aqua Affinity enchantment on your helmet. Aqua Affinity removes the underwater slowdown, and Conduit Power stacks its Haste on top. With both, plus your feet planted on a solid block, you break blocks at land speed or better. Conduit Power alone still helps, but if you’re doing serious underwater digging, pair it with Aqua Affinity.
How to get Conduit Power
You need two things: a conduit block, and a frame of the right blocks built around it underwater.
Crafting the conduit
A conduit is crafted from one Heart of the Sea surrounded by eight nautilus shells in the crafting grid. Both parts take some ocean work to collect.
The Heart of the Sea comes from buried treasure. You find a buried treasure map inside shipwreck or ocean ruin chests, follow it to the marked spot, and dig. Every buried treasure chest holds exactly one Heart of the Sea, so one map equals one conduit’s worth.
Nautilus shells are the slower part, since you need eight. They drop rarely from drowned that spawn holding one, you can fish them up as a treasure catch, and wandering traders sometimes sell them. Fishing with a Luck of the Sea rod is the most reliable steady source if you don’t want to hunt drowned.
Building the activation frame
A conduit on its own does nothing. It has to sit in water and be surrounded by a frame built from specific blocks: prismarine, prismarine bricks, dark prismarine, and sea lanterns. Any mix of those four works, so you can build the frame from whatever prismarine you’ve gathered from monuments.
The frame is a cage around the conduit. Picture three rings crossing through the block, one on each axis, forming an open box with the conduit floating in the middle. The blocks sit one space away from the conduit, not touching it directly. The whole structure has to be underwater, and the conduit itself needs water on all sides.
Once you place enough frame blocks, the conduit opens up, spins, and starts pulsing. That animation is how you know it’s active and giving off Conduit Power. If it stays closed and dark, something in the frame is wrong or the conduit isn’t fully surrounded by water.
Range and power levels
How far the effect reaches depends on how many frame blocks you place. A conduit switches on with a minimum of 16 blocks. You can keep adding blocks up to a maximum of 42, and each step up extends the range the effect covers.
At the full 42 blocks, the conduit reaches its maximum: Conduit Power covers a radius of 96 blocks around it. That’s a large sphere of ocean, enough to blanket a good-sized base or a whole monument you’re clearing out. If you only care about a small work area, the 16-block minimum is fine and cheap. For a base you’ll live in, it’s worth gathering the prismarine for the full frame.
The conduit’s mob-attack range doesn’t scale the same way. It always reaches 8 blocks, no matter how big the frame is. So the effect can cover you 90 blocks away, but the conduit only fights mobs right next to itself.
Tips and common mistakes
A few things trip people up the first time they set one up:
- The conduit must be underwater. Building it in an air gap, then filling the room later, is a common miss. Place it in water source blocks and keep water all around it.
- Only prismarine types and sea lanterns count. Regular stone, bricks, or other blocks in the frame do nothing. If your frame won’t activate, check that every block is one of the four valid types.
- The effect fades out of water. Step into an air pocket and the timer starts running down. Stay in the water to keep it.
- Add Aqua Affinity for real mining speed. Conduit Power’s Haste alone won’t get you to land speed underwater.
- You don’t need to be right next to it. Once it’s active, the effect follows you anywhere inside its range, so you can put the conduit somewhere safe and central.
If you’re clearing an ocean monument, a temporary conduit changes the whole job. Set one up nearby before you start draining or fighting guardians, and you get breathing, vision, and the mob-attack all at once while you work.
Frequently asked questions
How many blocks do you need to activate a conduit?
At least 16 frame blocks made of prismarine, prismarine bricks, dark prismarine, or sea lanterns. That’s the minimum to switch it on. The maximum is 42 blocks for full range.
How far does Conduit Power reach?
With a full 42-block frame, the effect covers a radius of 96 blocks. With the 16-block minimum, the range is much smaller but still enough for a tight work area. More frame blocks means more range.
Does Conduit Power work out of water?
The status effect only applies while you’re in water or standing in rain. Step into an air pocket and it fades after a few seconds. The conduit stays active, but you have to be in the water to feel the effect.
Does Conduit Power let you mine at full speed underwater?
Not on its own. It gives a Haste boost, but underwater mining is still slowed unless you also wear a helmet with Aqua Affinity. Use both together for full-speed digging.
Can a conduit hurt mobs?
Yes. An active conduit deals 4 damage every two seconds to hostile mobs within 8 blocks, as long as they’re in open water with a clear line to the conduit. Drowned that approach your base get worn down automatically.
What do you need to craft a conduit?
One Heart of the Sea and eight nautilus shells. The Heart of the Sea comes from buried treasure; the shells drop from drowned, come from fishing, or sell from wandering traders.
Can you turn a conduit off?
There’s no switch on the conduit itself. It stays active as long as it’s underwater with a valid frame around it. To shut it down, break enough frame blocks to drop below the 16-block minimum, or remove the water around the conduit so it’s no longer submerged. Put the blocks or water back and it powers up again.
Is it worth building?
If you spend any real time underwater, yes. A conduit removes the two things that make the ocean annoying, drowning and bad visibility, and speeds up your mining on top of it. Gather one Heart of the Sea and a stack of prismarine, and you’ve got a permanent underwater home base that also thins out the drowned for you.
