腐化草墙 is a type of 墙. Like the 草 of 腐化之地, it is a dark hue of purple. It can be destroyed, but not harvested, making it unobtainable as an item.
Corrupt Grass Walls cannot be created by the player like most other walls, but it can be converted from Grass Walls, Flower Walls, and Jungle Walls (both natural and those bought from the 树妖) by using 紫溶液 sprayed with the 环境改造枪, or throwing 邪水. As the Clentaminator affects a rather large area, creating areas of localized Corrupt Grass Walls without converting blocks and other wall parts may be difficult, making throwing Unholy Water more viable.
- It appears that Corrupt Grass Walls can adopt the small flowers featured on Flower Walls and Jungle Walls, given those types have been used to create the Corrupt Grass Wall. This feature will even persist if the wall is cleansed with 绿溶液 in the Clentaminator, or 净化粉 which will always yield a flowerless Grass Wall (even if the original wall was a Flower Wall or Jungle Wall), and re-corrupted again.
