Beacon

It'll be a compact block like packed ice, it'll be purposely hard to make. It will take 10 crafts, first regular copper block, then craft 9 compact copper to make a compressed copper block, on and on. But soon later you can't Craft it by hand, so add an new block like a compressor (idk) to make it, and at any time put 5 in a crafting table and place it like gunpowder in TNT recipe and surround it with obsidian, add it to a beacon and it will extend range of effects!
