Covalence dust comes in 3 tiers; Low (Green), Medium (Cyan) and High (Blue). The amount of covalence dust needed to repair a tool corresponds to the amount of stone/ingots/gems needed to craft the tool eg. 3 low covalence dust is needed to repair a stone pickaxe which was crafted from 3 cobblestone, and 1 low covalence dust is needed to repair a stone shovel which was crafted from only 1 cobblestone.
Note: Enchantments will be lost when repairing tools and armor.
