This mod adds cursed earth, which functions similarly to the cursed earth found in Extra Utilities 2 by RW Tema. In this iteration, cursed earth will spawn mobs on top of itself when the light level is less than 8. The mobs spawned is dependent on the biome, dimension, and structure in which the cursed earth is placed. If other mods installed include mobs that spawn naturally, the cursed earth will spawn those mobs as well. Mobs will be spawned about once in every 3 seconds, and the more mobs there are, the fewer mobs will spawn. One Cursed Earth is obtained by crafting soul soil with four wither roses in the crafting table. Cursed Earth will not spread to other grass blocks, so the only way to get more is to craft more. This is a Forge only mod, so there will be no Fabric port.
