Love the mod.
Going to use it for our server.

Haven't tested with tiered items, depending if it does cover all drills at a parent level or not I will most likely modify it for that and make a few tweaks on power and range.
*Will make it private and link back to here.

Have you attempted to hide the broadcast of the beacon, so people are not aware of the location of the block?
