Cursed Earth (Extra Utilities)

Cursed Earth is a block added by Extra Utilities and is created by the activation of a Division Sigil. When Cursed Earth is exposed to sunlight, it will randomly catch fire and revert into regular dirt. This fire will in turn cause other nearby Cursed Earth to burn in a chain reaction. However, it takes a reasonably long time to burn, thus making it relatively easy to grab the morning after the activation ritual, when enemies are no longer spawning.

Cursed Earth can only be obtained with a tool that has Silk Touch, else it will turn into dirt upon digging. It cannot initially be obtained in any other way. However, after obtaining the first block of Cursed Earth, it can be placed into the world, at which point it will spread to nearby grass and dirt blocks. This process can only occur in darkness.

Spawn rate of hostile mobs is much higher on it than of any other block. It will spawn mobs even if the player is far from it as long as the area is chunkloaded. Vanilla spawners placed above cursed earth will continue to spawn when the player is outside their normal range. The Magnum Torch does not interfere with Cursed Earth spawning. However, when exposed to high light levels, Cursed Earth will stop spawning enemies.

Any monster that's spawned on Cursed Earth, or that walks over cursed earth, will be given a speed effect.
