Description: This mod adds one block: the nether chest. It serves a counterpart to the ender chest, having a special ability based on the nether dimension. When items are stored in nether chest, their normal stack size limit is multiplied by 8 due to the way the nether compresses space by a factor of 8. This stack size increase also applies to tools and any other items that aren't normally stackable.
I'm setting up a server with a lot of tech mods and nether chests are a major quality of life improvement when dealing with machines like quarries which output large quantities of a few different items/blocks.
