Covalence Dust
Covalence Dust is created by combining various resources. It can be used to repair various kinds of tools and armor.
To repair things, left click with a Philosopher's Stone (or Aux1+left-click in MCL) to open the Repairing menu. Then, place Covalence Dust in the left slot and the damaged tool/armor piece in the middle slot. The item will instantly be repaired and put into the output slot.
The type of Covalence Dust needed to repair an item depends on its EMC value. The amount depends on the number of items it takes to craft (so 3 for a pickaxe, 8 for a chestplate, 1 for a shovel, and so on).
