Repairing - TheMarstonConnell/randomlootmod GitHub Wiki
Repairing tools is now done in vanilla anvils. The catch? You must use Random Clusters to repair your tools.
Clusters are made from 4 chunks which are made from 4 shards which can be obtained through blasting cases away in the blast furnace.
Also naming tools is just the same as vanilla but you will lose your fancy colored name.
