Conduit

A conduit is a small waterlogged block. It gives nearby players the Conduit Power status effect when powered by placing a certain configuration of blocks.

Usage
When activated, conduits give the "Conduit Power" effect to all underwater players within 42-96 blocks (similarly to beacons). This effect stops the breath meter from decreasing, gives underwater night vision, increases mining speed, and damages nearby hostile mobs

To activate, a conduit needs at least 16 prismarine, sea lanterns, or prismarine bricks 2 blocks away on the same X, Y or Z plane. It also needs to be in the center of a 3x3x3 cube of water sources or flowing water. A conduit with the minimum 16 blocks has a range of 42 blocks; every additional block after the 16th adds around 2.3 blocks to the range (specifically, the distance is ). A fully powered conduit (42 blocks) has a range of 96 blocks and also damages hostile mobs within 8 blocks by every 2 seconds.

Trivia

 * When it is activated, the conduit displays the heart of the sea's texture in the center of its model.
 * Despite the conduit's small appearance, its hitbox takes up a full block.
