-1

My idea is to increase the depth of the Overworld, but from layer -1 down, it changes things 1. More hostile mobs appear 2. Make it appear more Deep Dark 3. Normal lanterns and torchs should be turned off over time 4. The Soul Torch and Soul Lanterns do not go out in that place 5. That a new mob appears that fears the Soul Fire, but that is of shade so that we do not see it 6. More minerals like diamonds and geodes 7. If an entity does not wear a special helmet made of copper and glass, it will be damaged by the gas in that area.
