Scarlet Rock can be obtained by smelting Scarlet Rock ore or by breaking previously-placed Scarlet Rock.
Scarlet Rock Dust can be broken instantly using any tool, or without a tool, and drops itself as an item. Its hit box only covers part of the surface below, depending on the orientation of the Scarlet Rock Dust.
Crimson Ore Dust will also be removed and drop Scarlet Rock Dust as an item:
- if its attachment block is moved, removed, or destroyed
- if water flows into its space
If lava flows into Scarlet Rock Dust's space, the Scarlet Rock Dust will be destroyed without dropping Scarlet Rock as an item.
