Dark Infection - Alec-WAM/CrystalMod GitHub Wiki

The Dark Infection is an explosive that infects your world with darkness which will spread slowly and ruin your world. No one would ever dare to step on the infection because you will start to wither away. The Dark Infection is always spewing out darkness, the only way to stop it is to break it, but over time it encases itself in blocks denser than obsidian that you must find a way to break through.
