Taintwood Log (Thaumcraft 5)

Taintwood Log is a block from Thaumcraft 5. It can be found in Tainted Lands Biome, or when Fibrous Taint growing over Wood blocks corrupts them. Taintwood Logs act as a source of taint, and can be harvested with an Axe. An Ethereal Bloom will purify Taintwood Logs, converting them to Degraded Taint Dust.
