A conduit is a beacon-like block that provides Conduit Power and attacks hostile mobs underwater.

Obtaining[edit]

Conduits drop as an item when broken with any tool or by hand, but a pickaxe is the fastest way to break it.

The conduit and water are required. The frame
must include 16-42 blocks of prismarine, dark
prismarine, sea lanterns, and/or prismarine
bricks. Unused frame blocks and empty spaces
can be anything.

When activated, conduits give the "Conduit Power" effect to all players in contact with rain‌^{[Java Edition only]} or water, within a cylindrical range of 32-96 blocks. This effect stops the breath meter from decreasing, gives underwater night vision and increases underwater mining speed (slower than above water mining). Conduit power also damages any hostile mobs, like drowned and guardians, within a range of 8 blocks of the conduit. Conduits can be activated in any biome and at any height or depth.

To activate, a conduit needs to be in the center of a 3×3×3 area of water (source blocks, flowing water, and/or waterlogged blocks), which itself must be enclosed within an activation frame. The frame is built out of blocks in three 5×5 open squares centered on the conduit, one around each axis. Only prismarine, dark prismarine, prismarine bricks and sea lantern blocks in the frame contribute to activation. A minimum of 16 blocks are required and produce an effect range of 32 blocks. Prismarine-type slabs (including double slabs) and stairs cannot be used to activate the conduit.^[1]

The effect radius of the conduit is 16 blocks for every seven blocks in the frame, though the effect does not activate until the minimum of 16 blocks is included in the build. Thus, it extends to 48 at 21 blocks, 64 at 28 blocks, 80 at 35 blocks, and 96 with a complete frame of 42 blocks. A complete frame also carries the additional advantage of attacking hostile mobs within 8 blocks of the conduit by 4 every 2 seconds, if they are in contact with water or rain.

Other blocks used as part of the frame (including prismarine stairs, slabs, and double slabs) have no effect on activation. Any blocks outside the frame but within the 5×5×5 cube that encompasses it likewise have no effect.

Light source[edit]

Conduits emit a light level of 15, the brightest light level in the game, whether activated or not. However, when placed on land, conduits do not emit light.

	18w20b		The eye of the conduit now show whether it's hunting for hostile mobs or not: it shows an open eye when it's looking out for hostile mobs, and a closed eye otherwise.
	18w20c		Dark prismarine can now be used to activate a conduit.
1.13.1	18w31a		Conduits are now properly waterlogged.

Trivia[edit]

When it is activated, the conduit displays the heart of the sea's texture in the center of its model.
When destroyed by an explosion, the block always drops as an item.
If it had been possible to activate a conduit with fewer than 16 blocks, its effect range would be 0 at 0–6 blocks, 16 at 7–13 blocks, and 32 already at 14–15 blocks.
The achievement obtained by activating a conduit refers to the system of whirlpools in Nordland county, Norway.
