Starglow Cavern Puzzle Solution
To complete theGenshin ImpactStarglow Cavern puzzle, players must start the four stone mechanisms scattered around the area.
The Fourth Mechanism
After starting the third mechanism, players must make their way to the opposite end of the ledge. There, on the same ground level as the runes and Ruin Grader, and among the rocks that rest near the corner edge of the cliff, sits a small deposit of Scarlet Quartz. Players who have already collectedthe Crystal Agate in the Cellnorth of here will know that they must destroy this deposit and collect the quartz so that a red aura envelops their character.
With the red aura active, players will be able to attack and destroyGenshin Impact’s magical icealong the side of the rocky ledge. There are two mounds of the magical ice- one holds the last mechanism and one contains a loot chest - so players may have to return to the deposit of Scarlet Quartz to regain the red aura to get them both. Once the correct mound of magical ice has been destroyed, players can start the last mechanism.
Some players have reported a bug in this puzzle that causes the Ruin Grader to be awakened after the third mechanism is started; after the fight is completed, the fourth mechanism becomes inoperable and none of the chests appear. At the time of writing, there appears to be no workaround, and whileVersion 1.3 Inazuma Weapons have been leaked, there’s still no word on which bug fixes may be included the update.
Genshin Impact’s Ruin Grader Fight
The Ruin Grader has a lot of HP, and its attacks are hard-hitting. Players will want to learn the Ruin Grader’s moves, learning how to dodge each of them. As for the makeup of the party, players will want to choose at least one Claymore character and one ranged DPS. This will allow them to easily attack the enemy’s weak points.
