Crusted Taint (Thaumcraft 6)

The Crusted Taint is a block added by Thaumcraft 6. It is created by Taint infecting most plant-based blocks (like pumpkins or planks), other than logs. If not supported by a block underneath or any log in a 3×3×3 area around the block, it has a chance to fall down like sand, and can fall sideways if supported only by other Crusted Taint blocks.

If Crusted Taint is further away than 32 blocks (horizontally) from a Taint Seed, it will slowly turn into Flux Goo.
