Tainted Rock (Thaumcraft 5)

Tainted Rock is a block from Thaumcraft 5. It can be found in Tainted Lands Biome, or by Fibrous Taint growing over Stone. Tainted Rock does not act as a strong source of taint and will not taint more blocks, but can spawn Fibrous Taint. An Ethereal Bloom will purify Tainted Rocks converting them to Porous Stone.
