Appendage Fragments were items in Xenoblade Chronicles X. They were exclusively obtained by destroying the appendages of Nemesis enemies. These items are now unobtainable after the shutdown of Wii U online services.
While the Nemesis mission remained available, Appendage Fragments could be sold for Credits via the Inventory, or exchanged for Reward Tickets via the Global Nemesis Battle Spoils option at the Network Console.
If the Nemesis was defeated, one type of Appendage Fragment was randomly chosen to be converted to a very rare material specific to that enemy, and the rest were converted to Reward Tickets.
If the Nemesis fled without being defeated, all Appendage Fragments from that enemy were converted to Reward Tickets.
