Final Challenge of the Sage is a quest in Xenoblade Chronicles. It can be received from the Nopon Sage in Makna Forest after clearing the Mechonis Core. Nopon Sage lies at the Ether Crystal Deposit area north of the Divine Sanctuary and southwest of Waypoint Beacon, from 12:00 to 15:00. He will only give the quest to Riki. After completing the quest, RIki's fifth skill branch, Heroism, will be unlocked.

"You have completed the final test. The Nopon Sage is impressed and gives you a gift."
