Requires the library mod Collective.
Underground Beacons allows beacons to function, no matter how many solid blocks are above it. You'll be able to place it anywhere below the surface, without the need to dig straight up to make room for the beam. It'll pass through any block.
It makes using beacons at the deepslate level a lot more convenient.
Place it down, give it some time, and woosh!
