Silt Blocks are soils very similar to Sand Blocks that appear at cavern layer. It is subject to gravity and will deal damage to any player or mob they fall on. Unlike sand, It is immune to the Hallow, the Crimson, and the Corruption. It looks similar to Ash Blocks, but is a lighter color.
It can be used in the same way as sand, and can be used to fill lava pits. It can also be used in creating traps, since it causes damage to whatever it falls onto.
- When the Wall of Flesh is defeated for the first time, and the "Spirits of Light and Darkness" are unleashed, Silt Blocks inside the new Corruption, Crimson, and Hallowed biomes will be converted to Ebonsand and Pearlsand respectively, much like regular sand. After this initial conversion however, It will not be affected by the spread of Corruption and Hallow.
- Silt and Slush blocks can be placed on the Extractinator to create "something more useful", including gems, coins, and ores.
