I Am the First, the Last, and the Only - Episodio 5

On a misty mountain, treasure hunters search Lord Shaw's ruined 10,000-year-old magical artifacts and find one intact relic near the summit. To claim Lord Shaw's legacy they must pass a barrier of sword energy; during attempts lightning strikes unpredictably and one seeker surprisingly predicts the hits. As the group pushes forward, Yuna suddenly loses her spiritual power and falters, leaving several team members shaken. Insults fly—one calls another 'Level One Refining Stage trash'—and one remaining seeker refuses to let Yuna be dragged down, deciding they must press on to reach the summit.
