Fractured Fossil is a fossil type. Fossils are a special type of currency introduced in the delve league that can be socketed into resonators to modify the crafting behavior in specific ways. Fossils can also add special Delve modifiers.
Mirror of Kalandra copies an already finished item. However, Fractured Fossil craft a random item and copies it afterward. For the later, the result is unpredictable.
Mirror of Kalandra can be used for any type of items. However, fossil must be socketed into Resonator to influence item crafting. It can only influence normal and rare items.
