LUMP aims to eradicate torch spam around your base,
without affecting your mob grinders or other farms.

It achieves this by adding a craftable block, called the Amethyst Beacon, which prevents mob spawns within its range, but only for blocks that would be otherwise safe during the day (it is skylight based).

This means:
✅ you only need to light up the interiors of your base
✅ your mob farms should still work (as long as they are dark)
✅ caves are still dangerous until you light them up

✨ This mod also includes a color-coded light overlay to see which blocks are spawnable and which are safe,
the overlay is always displayed when you have the fashionable Amethyst Goggles equipped on your head.

⛏️ This mod aims to be 100% survival friendly.
