I found a server where everyone is basically living underground now. There are 16 custom armor sets and each one takes a huge amount of raw ore to make. People log in and just mine for weeks like it is their whole life.
The armor is actually wild. Some sets give night vision underground. Some give haste that keeps building the longer you mine in one direction. Some make mined blocks go straight into your inventory. One even helps crops grow faster just by standing near them.
Nobody has finished a full set yet but raw ore is already getting traded and put on the auction house and prices are going up. The first person to finish a full set gets instant bragging rights. The server is on version 1.21.10.
