As the quest proceeds NPC Titu will ask the traveler to help resolve the Shadow Pin issue and reinforce the seal. Go northwest with NPC Titu to the Lesser Shadow Pin’s location. Defeat the enemies in the area, then interact with the golden inscription.
Repair the inscription
Next, interact with the golden inscription near the Lesser Shadow Pins to start the repair. This will trigger a challenge where the traveler needs to break the small engraved stone pillars around the Lesser Shadow Pins and collect the inscription’s power.
To break the engraved stone pillars, travelers need to use the Tepetlisauri Saurian Indwelling. Saurians are dragon-like creatures native to Natlan in Genshin Impact. They can seamlessly make paths by tunneling through rocks, and climbing mountain walls.
Finally, defeat the enemies that spawn in the area and complete the repair.
