A Blackstone Stairs block is a blackstone variant of stairs, commonly used in Nether-themed or medieval builds due to its dark, rugged texture. Blackstone Stairs can be mined fastest with a pickaxe; otherwise, they drop nothing.
These stairs naturally generate in bastion remnants and can be crafted from Blackstone or obtained via stonecutting. Additionally, they can be placed under a note block to produce a bass drum sound.
