Cursed Earth (Extra Utilities)

Cursed Earth is a block added by Extra Utilities and is created by the activation of Division Sigil. When Cursed Earth is exposed to sunlight, it will randomly catch fire and revert into regular dirt and will cause damage to everyone standing on the block. This fire will in turn cause other nearby Cursed Earth to burn in a chain reaction. Cursed Earth can be obtained with a tool that has Silk Touch, else it will turn into dirt upon digging. 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. It cannot be obtained any other way than performing the activation ritual.
