The Last Day of Remuria is a Genshin Impact World Quest in the Canticles of Harmony: Second Movement – Prisoner in Shackles series, set in an underwater region hidden in Petrichor. One of the main goals of the quest is to break the chains binding Scylla, who has been subjugated in the Sea of Bygone Eras.
Break the Chains That Bind Scylla Genshin Impact Last Day of Remuria
There are three “chains” binding the whale-like dragon Scylla, but the chains are more like glowing lines that lead you to three areas in the Sea of Bygone Eras. Your goal is to follow the chains to each area, solving three puzzles to complete the objective. While they can be completed in any order, I recommend following the order outlined below to avoid running into potential bugs.
Before you begin, I recommend taking a battle-ready team with a Geo Shield Breaker, as the golems in Petrichor have Geo Shields. When you are ready, follow the first chain to the southern part of the Sea of Bygone Eras, into the cave that is in the area circled above. Inside the cave, you will encounter three golems. Defeat them to trigger a dialogue.
After the dialogue is complete, use the special interaction button to switch to Symphony Mode and hold the Elemental Skill button in front of the tower (as pictured above) to release a sound wave. Doing so will trigger a short cutscene where Scylla's chain is released. If this doesn't happen, move closer to the tower and try again. Don't forget to claim the Exquisite Chest reward that spawns afterwards.
