/dev/null doesn't help because with an Efficency 5 Shatterer with Rank SS and the Ring of Thor you clear a series of 9x9x5 "rooms" at running pace for the Kami armor. Basically you are mining that fast that even with /dev/nulls for all non ores your inventory fills up in a few hits at running pace leading to it taking longer to mine this way, due to inventory management, than with a slower mass manual method (Hammer mostly) Haven't investigated the compression methods available with Botania\Thaumcraft\Blood Magic but I doubt there will be anything that makes this method viable unlike the original in Equivalent Exchange. In any case I basically made the Shatterer and ranked it up to SS because I could lol
