Tainted Rock (Thaumcraft 6)

The Tainted Rock is a block added by Thaumcraft 6. It is a block that occasionally inflicts entities standing on it with Taint Poison. It is created when stone blocks like Cobblestone or Stone are in the vicinity of a Taint Seed or its larger variant. When Tainted Rock is placed out in the world away from Taint Seeds, they gradually become Porous Stone.
