Corrupt Seeds

Corrupt Seeds are seeds which can be planted on dirt and will then spread The Corruption in all directions. The corruption will only spread if the seeds are planted at positive elevation.

As a warning to players creating Corruption farms or simply small patches of corruption, do note that thorny bushes will grow on player planted corruption and these growths can bridge small gaps of 3-4 spaces across and upwards, spreading corruption on the other side which may create unwanted areas of corruption. It is therefore recomended to either leave larger spaces between non-corrupt grass/dirt or to plant a Sunflower on the edges of where you wish it to spread to.

They're a very common drop from Boss monsters.
