Silt Blocks are soils that are very similar to 沙块s that start appearing from the 洞穴 地层. It is affected by gravity and will deal damage to any player or mob they fall on. Unlike sand, It can stop 神圣之地, 猩红之地, and 腐化之地 from spreading. It looks similar to 灰烬块s, but is a lighter color.
- When the 血肉墙 is defeated for the first time, and the "Spirits of Light and Darkness" are unleashed, Silt Blocks inside the new 腐化, 猩红, and 神圣 biomes will be converted to 黑檀沙/猩红沙 and 珍珠沙 respectively, much like regular sand. After this initial conversion however, Silt Blocks are not affected by the spread of Corruption and Hallow.
- Just like 雪泥 and other forms of sand, it disappears when it falls on a rail track.
- Silt can be used in the same way as 沙 to fill lava pits. It can also be used in creating traps, since it causes damage to whatever it falls onto.
- 1.2：Stack limit increased from 250 to 999. Also can now be used in Stucco blocks and turned into "something more useful" via the 提炼机.
