Magma Blocks are unique solid cubes with a rough, fiery texture that emit light and cause fire damage when stepped on without crouching or wearing Frost Walker boots. They naturally generate in the Nether, particularly in basalt deltas, and can be used underwater to create bubble columns when placed beneath the surface, providing upward propulsion and replenishment of a player's air supply. These blocks also damage mobs, making them useful for mob grinders or defense mechanisms.
