Magma Block

A magma block is a light-emitting block found underwater in the Overworld, and more abundantly in the Nether. It deals burning damage while stood on, which can be prevented by sneaking. Underwater magma blocks produce bubble columns that pull entities downward and provide air.

Magma blocks can be mined using any pickaxe. If mined without a pickaxe, they drop nothing.

In the Overworld, magma blocks generate at the bottom of water aquifers in underwater magma in clusters of 1–8 blocks, and in sulfur springs in clusters of 1–3 blocks.
