The Ancient Crafting Stations are post-Equinox Worms crafting stations used to craft items dropped from the Ancients. They can be combined with a Furniture Dynamo and a Core of Terraria to make the Infinity Core, which can be used to craft almost any recipe in Vanilla and Ancients Awakened.
It is currently impossible to craft the Binary Fragmentation Reassembler without first crafting the Chaos Crucible, since Apocalyptite Plates can only be crafted using Ancient Crafting Stations, rendering the Binary Fragmentation Reassembler useless.
