As of snapshot 21w10a, the moss blocks now generate in the officially added lush caves biome. Although they are not yet generating in default worlds, they do generate in single biome worlds, which I believe is as official as default. Can we change it already, or should we wait until lush caves biome generate in default? Windwend (talk) 21:22, 10 March 2021 (UTC)
Only axes and hoes insta-mine moss, and only stone ones and better. Picks and swords don't insta-mine moss. You need haste X and Efficiency V on a netherite pickaxe to mine moss instantly. Since hoes are cheaper to craft and have the same durability as axes, this makes them the better tool to mine moss with.
It does not seem to convert sand or gravel blocks in 1.17. 184.108.40.206 17:12, 9 June 2021 (UTC)
