The soul conductor is a powerful transport block. Attaching two conductors with sculk and clicking one will transport you to the other. There are also complex mechanics involving more than two conductors, which are described in this document.
The soul conductor also has redstone interactions. When powered, it deactivates and cannot be entered nor exited. Any sculk that the conductor scans during the transport will trigger observers pointing into said sculk.

It’s crafted using two echo shards, making it a powerful, unique reward for the deep dark.
History
| 1.3.2 | + | You can now “pick block” positional anchors, soul seers, soul conductors, and pottery tables by control+middle-clicking them | |
|---|---|---|---|
| 1.3.0 | + | Soul conductors can now be disabled by powering them with redstone | |
| 1.2.2 | * | The soul conductor limit is now 2000, rather than 10000. This is to prevent excessive lag.
The soul conductor now warns you when you hit the limit, rather than failing silently | |
| 1.2.1 | * | Soul conductors now ignore doors | |
| 1.1.1 | * | Soul conductors now ignore trapdoors | |
| 1.1.0 | Beta 3 | * | There are now particles and sounds for multiplayer The limit is now 10,000 blocks instead of a measly 1,800 Tweaked the behavior of exit conductors
There’s also a fun new advancement for travelling more than 1000 blocks in one go using a soul conductor called “Thinking with Portals”. |
| Beta 1 | + | A new block crafted from 2 echo shards Connecting two soul conductors with a line of sculk and clicking one end will teleport you to the other You can find out more about this feature in its guide article. Yes, it’s so complex it has its own guide article. | |
