Strength Training

Access the Quest menu, navigate to the Story sub-menu, and go to the second page.

Select Noelle and confirm to unlock "Chivalric Training" by spending two Story Keys.

Teleport to Windwail Highland and proceed north towards the objective marker. Drop into the canyon to trigger a cutscene (a non-interactive cinematic the game plays automatically).

After the cutscene, you will control Noelle. Attack the three marked ore deposits with normal attacks.

Upon destroying the last deposit, four Geo Slimes will ambush you. Use Noelle's Claymore attacks. If your health gets low, use her Elemental Skill for a shield and healing.

Continue southeast down the path to encounter a Blazing Axe Mitachurl. Use Noelle's Elemental Skill for a shield and her Elemental Burst to increase ATK based on DEF, attack range, and change all attacks to GEO damage. If the Burst is unavailable, use normal attacks. A rockfall will occur after the fight.

Head south and speak to Belinda, a Knight of Favonius, who is next to the rockfall.

Attack the rockfall with Noelle to disintegrate it, revealing a Stonehide Lawachurl.

Defeat the Stonehide Lawachurl. Use Noelle's Elemental Skill for a shield to protect against its attacks.

Attack the six Blue Ore deposits (three on each side) to shatter them. Shattering the last one will trigger a cutscene and dialogue, concluding the quest and awarding Ending 2 - A Maid Above Ground.
